License Introduction

Licenses for controller features are managed through the Functionality Management System (FMS). This allows customers to tailor controller functions to their specific needs through a dynamic licensing scheme.

Licenses can be obtained for individual features or collections of features and can be deployed across multiple virtual stations. The licenses can be returned to the pool when they are no longer required. Licenses can be obtained through the Atlas Copco License Portal (ACLP). Licenses can be downloaded from the ACLP and managed/distributed through ToolsTalk, or can be stored on a FMS Portable (USB drive) to be inserted into the controller.

Note that the creation and management of a customer account in the ACLP is not covered in this documentation. Contact your local Atlas Copco representative for more information.

Licenses Overview

Configuration of features governed by licenses can be done even in the absence of an installed license. E.g. configuration of tightening programs and configuration of Multistep programs. Assigning these features to a tool or virtual station is also possible. Running the feature without a valid license, however, will require the installation of the appropriate license.

License enforcement is performed at two stages: assignment and runtime (trigger pressed). If a feature for which no license is installed is assigned to a Virtual Station, a red exclamation mark will appear at the Virtual Station View in ToolsTalk 2. The controller GUI will also show a warning triangle at the tool or task section (depending on what is missing). If a feature for which no license is installed is started (i.e. trigger pressed), an event will be presented to the user informing the user of which license is missing. It will not be possible to proceed without a correct license installed.

Running an unlicensed feature will, in most cases, result in a locked tool.

Many features and functions in the controller require a license in order to be assigned and used by a virtual station. There are three types of licenses:

Virtual Station Type

Fixed collection of features bundled together in a single package. The Virtual Station Type determines, among other things, what tools can be run, how many programs and sequences can be used, which tightening strategies are available, and the type of reporting that can be done. The features contained in each Virtual Station Type are features that often are used in conjunction with each other, or which have internal dependencies that require the presence of other features in the package. Virtual Station Types are assigned in their entirety to a virtual station. The virtual station can then make use of all features contained in the Virtual Station Type. In order to be able to perform tightenings, a Virtual Station has to be assigned a Virtual Station Type license. Depending on the license type, various tightening options will be enabled or blocked.

Virtual Station Feature

Individual features which can complement Virtual Station Types. A lot of features can be purchased as a single license.

License Sources

Licenses used on a controller can be pulled from several different sources. The number of simultaneous sources is limited to 10 (either 10 FMS Portable sources, or one License Server (TT2) in addition to 9 FMS Portable sources). If you would like to add licenses from a source when the source limit (10) has been reached, all licenses from one source need to be removed from the controller to make room for licenses from the other source.

Source Overview

The Source Overview tab (License assignment > Source Overview) provides the user with an overview of the licenses installed on the controller, as well as where they were installed from. A maximum number of 10 different sources can be displayed here, and each will be designated with FMS P (for FMS Portable, or dongle), or License Server (TT2).

Clicking on any license source will present that source's detailed license source information. It lists the source name and type, as well as the number and type of licenses in each category (Virtual Station Type, Virtual Station Feature and Controller Feature).

Supported Tools

Tools supported by a Virtual Station may vary depending on the Virtual Station type on the controller.

Installation and Upgrade

• License Installation
  • Installing Licenses on the Controller
  • Removing Licenses from the Controller

License Installation

• Installing Licenses on the Controller
• Removing Licenses from the Controller

Installing Licenses on the Controller

Note that licenses sources are limited to 1 License Server (TT2) and 9 FMS Portables (dongles) simultaneously. Licenses are installed either through the server (ToolsTalk 2) or FMS Portable. If the license source limit is reached, all licenses from one source need to be removed from the controller in order to add licenses from another source.

Before installing licenses through the server (ToolsTalk 2), make sure that the controller time is synced with the server time.

Installing from the Server

Distributing server-based licenses is done through ToolsTalk 2. Please refer to the ToolsTalk 2 User Guide for instructions on installing licenses.

In order to be able to install licenses using ToolsTalk 2, the correct license server needs to be configured:

Installing from FMS Portable (USB)

The Functionality Management System (FMS) uses a special FMS Portable device to transfer functionality to and from a controller. The USB flash drive contains both a general purpose memory area and a trusted storage area that is only accessible by the License manager in a controller. The purchased feature items are downloaded from Atlas Copco to the general purpose area. The first time the FMS Portable is inserted into a controller with a License manager, the file is detected and decoded and the feature items are transferred to the trusted storage area that is only accessible from a License manager.

If you have a USB drive with the licenses installed, perform the following steps to install them on the controller.

The user will be presented with events on the controller for both license transfer start and end.

Automatic License Assignment

A process control license is assigned automatically to the first created virtual station. The license is assigned if it is available on the controller and no other license is assigned to the virtual station. The automatic license assignment occurs during upstart of the controller.

License sync

Existing licenses are checked against the license server every two hours. If no response from the license server is obtained within a 14 day period, the affected licenses will be revoked. The user will also be warned when licenses are about to expire. When a license is within 7 days of expiration, the user will be presented with a warning once every two hours. If licenses are not renewed, they will expire and the affected functions will no longer be available.

Removing Licenses from the Controller

One way of removing an FMS Portable-installed licenses are described, for instructions how to remove server-installed licenses, please refer to the ToolsTalk 2 User Guide.

WARNING

Risk of injury

A change in the configuration of the tightening program may cause unexpected torque, rotational direction, or speed in the system(s) where the tightening program is currently in use. This could result in severe bodily injury and/or property damage.

• Check the tightening program configurations after adding a new program or after applying changes to an existing program.

Controller features, such as the Low Reaction Tightening Strategies and controller-wide functions among others, require licenses distributed through the Functionality Management System (FMS). Whereas configuration of features is possible without specific licenses, the assignment and use of those features will require the correct license to be installed on the controller. Please refer to Licenses (FMS) for more detailed information on licenses.

The Power Focus XCPower Focus XC tightening programs need parameters to be set in order to perform tightening. Selecting a Strategy and either the Target torque or Target angle are mandatory. Other settings are optional, such as Soft start, Selftap, and Torque compensation. It is also possible to monitor the tightening as it progresses by adding limits within which the torque, or angle the nut turns, must remain.

The tightening procedure is divided into four steps: Start, Rundown, Tightening and Stop.

Tightening Programs

By selecting the tightening program it is possible to choose the method for applying clamping force (or pre-load) to the joint. Different joints require different strategies for how to apply the desired clamping force and to minimize unwanted in-service effects.Power Focus XCPower Focus XC can store up to 1,000 tightening programs.

In the Web HMI, a maximum of 1,000 tightening programs can be created.

In the Mobile HMI, a maximum of 500 tightening programs can be created.

• The TurboTight strategy, enables the option to use Manual programming or Quick prog - for more information, see the paragraph TurboTight.

• The Quick step, Two step and Three step strategies enable the choice of tightening towards a Target torque or a Target angle value.

• The External result strategy, is used when OK tightenings are indicated by an external digital signal - for more information, see the paragraph External result.

All tightening programs require that you at least set the Target torque or Target angle value.

TurboTight

TurboTight is the default tightening strategy and it is designed to perform a very fast and ergonomic tightening based on the maximum speed of the tool (Tool max speed). This strategy has two options:

• Quick prog, that requires only the Target torque to be set to perform the tightening.

• Manual, that allows the user to configure several tightening parameters.

To minimize the risk of unexpected jerk at the end of the tightening when using the TurboTight tightening strategy, make sure to activate Time monitoring.

To minimize the risk of unexpected jerk at the end of the tightening when using the TurboTight tightening strategy, make sure to set the Time Max Limit.

Time Max Limit is enabled by default, but it is necessary to setup the related values. In the tightening stage, set Angle Limit to From Rundown Complete.
Set Time Max as low as possible, without stopping the normal tightening. In the rundown stage, set Rundown Complete Torque so that it is triggered when the torque start to increase.

Depending on the joint properties, for example if the joint is very stiff or very soft, a different tightening strategy than TurboTight might be needed.

TurboTight is not available for Joint Control.

Fine-Tuning the TurboTight Strategy

TurboTight tightening strategy points to the target torque, and the result can be below or above the target. The most important parameter for TurboTight tightening strategy is the speed. It is possible to keep maximum speed for most tightenings, but if all/some of the tightenings overshoot, decrease the speed in small steps. Rundown Complete Torque is not used for controlling of the tightening; it is only used for calculating of limits and results.

Quick Step

Quick step is a tightening strategy used to reduce the joint’s preload scatter by adding an initial step with a given torque and speed, and then reducing the target speed in the final step.

Two Step

The Two step strategy is very similar to the Quick step strategy except that it adds a small time delay between the first step and the final step, to further counteract short-term relaxation effects in the joint.

Fine-Tuning the Two Step Strategy

When the First target is reached, the tool makes an immediate stop for a specified time before it continues with the final step. The First torque value and the Pause time should be chosen to improve ergonomics for hand-held tools.

Three Step

The Three step strategy adds a loosening step between the first step and the final step, to overcome short-term relaxation effects due to embedment, and reduce preload scatter. This is sometimes used to condition the joint. This can be useful in, for example, joints with many adjoining surfaces and will have a greater effect on new parts than on reused ones, due to the smoothing of surfaces, which reduces embedment.

Conditioning the joint is done by tightening the first step to a given torque, First torque, and then releasing the load by turning the nut a specified Conditioning angle and then retightening the nut to its Target torque or Target angle.

The target torque can be lower than the torque reached during the first step after rundown. In order for the target torque to be lower than the first torque, set target torque (Tightening parameters > Tightening step > Final step > Target torque) to a value lower than First torque (Tightening parameters > Tightening step > First step > First torque).

If Angle is used as a target in the tightening program, the Target angle is measured from the position at the end of the loosening step (conditioning).

Behavior of Measure torque at, and Measure angle to

The Max torque value and Value at peak torque measured under Result evaluation for Measure torque at and Measure angle to, respectively, represent the highest values measured over the entire tightening. This means that if the Target torque is set lower than the First torque, the Result evaluation value will be higher than the end value. In order to view the tightening's final value, both Measure torque at, and Measure angle to should be set to Value at shutoff.

Fine-Tuning the Three Step Strategy

When the First target is reached and the conditioning step is entered, the tool makes an immediate stop and reverse before it continues with the final step. This conditioning step may need to be fine-tuned to improve ergonomics for hand-held tools.

STwrench

The STwrench is connected to a controller using a wireless connection and is configured through the controller GUI or the web GUI.

The STwrench is configured under the tightening menu in the same way as the other tightening strategies.

The STwrench has a Rapid Backup Unit (RBU). The RBU defines the wrench function and stores the tightening programs. The controller supports currently only the RBU of the type Production.

The STwrench End-fitting tool (socket) contains a RFID TAG with a programmable number. This wrench uses this number to automatically recognize the tool and which program that can be used. The RFID TAG also stores the torque and angle correction coefficients.

The STwrench has several programs both for production tightening and for quality control.

The STwrench can only support tightening programs supported by the tool (Wrench Production and Wrench Quality).

For more information about the STwrench, see the STwrench User Guide (printed matter number 9836 4134 01).

Pulsing Tool Strategies

The strategy can be selected if the controller software version supports the tightening program. Pulsing tools can achieve a higher torque compared to normal rotating tools.

Pulse Tightening Program

Start

During the start step, the tool rotates in a speed mode without any pulsing.

Rundown

During rundown, the tool can use either speed mode, with a constant motor speed, or pulse mode. The selection is made depending on the encountered torque and the given torque limits within the configuration.

Tightening

Pulse Tightening with Direct Driven Electrical Tools

The principle below is applicable for direct driven electrical tools. It is applicable to the Atlas Copco SRB series of tools.

The pulse tightening uses a technique of pulsing the electrical current in the motor and has two distinct features:

• An action current that adds positive torque in the tightening direction.

• A reaction current that creates a comfort reaction by applying a reverse torque.

A	Action pulse to apply tightening force.
B	Reaction pulse for comfort

The figure shows the general principle of a current pulse tightening strategy. The detailed curve depends on the tool type and the tightening algorithm.

The pulse period consists of two phases as shown in the figure with an action current and a reaction current. Each action pulse adds torque to the tightening until the final target is reached. Each reaction pulse creates a counterforce that provides a comfortable reaction.

The energy level of the action phase and the reaction phase are configurable parameters. The combination of these two parameters creates an efficient tightening combined with operator comfort.

Tightening using the TensorPulse Program

The principle below is applicable for direct driven electrical tool. It is applicable to the Atlas Copco SRB series of tools.

After each pulse period the resulting torque in the screw is increased. After a series of pulses, the final torque target is reached.

A	Maximum positive energy in pulse N
B	Maximum positive energy in pulse N+1
C	Increase in energy (torque)

The energy level in the action phase and reaction phase are user configurable parameters. The combination of these two parameters creates an efficient tightening combined with operator comfort. It is possible to set the amount of energy in the two phases as a percentage of the maximum energy that can be delivered in each period:

• Pulse energy; The amount of energy that is applied to each positive pulse as a percentage of the maximum energy that can be applied in the pulse period. The value is between 10-100%.

• Reaction force retention factor; The amount of energy that is applied to each reactive pulse as a percentage of the maximum energy that can be applied in the pulse period. The value is between 0-75%.

A	Reduced positive energy in pulse N
B	Reduced positive energy in pulse N+1
C	Resulting curve for torque build up using maximum pulse energy.
D	Resulting curve for torque build up using reduced pulse energy.

• A small Pulse energy (reduced energy) requires more pulses to reach the target torque as the torque is increased in smaller steps. Smaller steps provides better accuracy to terminate the tightening when the target is reached. Smaller pulses decrease tool movement and increases operator comfort.

• A correctly tuned Reaction force retention factor will create the desired operator comfort. If the factor is too high the operator feels a clockwise rotation of the tool. If the factor is too low, the operator feels a counter clockwise rotation of the tool.

• In an ideal configuration, the reaction energy does not create any loosening force. If the amount of pulses to reach the target value increases, the value is set too high and a small loosening occurs at each pulse.

The optimum values for the Pulse energy and the Reaction force retention factor need to be tuned for optimum performance of the tool and for best operator comfort.

Impulse Single Step Tightening Program

Rundown

Tightening

Rotate

The Rotate strategy is primarily a strategy for testing and demonstration purposes. When the tool is allowed to rotate freely, it turns the socket the specified angle using the lowest torque possible.

External Result

External result is a strategy used when an OK tightening is indicated by an external digital signal (and not by torque or angle values measured during tightening).

When the signal is sent, the Result view will show the value of the Target parameter provided in the tightening program (specified torque value, angle value, or text string). These (torque and angle) values do not represent actual measured values, but only inserted text.

Running the External Result Tightening Strategy with a Tool Connected

Tightening Program and Error Reporting Validation

The tightening program automatically validates with the parameter rules and tool properties as soon as new values are entered or changes are made. If the validation detects any errors they are reported with an error description.

Validation Error Reporting

If the validation gives an error, it is displayed with an icon next to the parameter or parameters causing the error. When you tap on the icon, a short description of the error is given.

Example (See image):

1. Target torque is set to 25 Nm with Final torque limits set to Torque min 23.75 Nm and Torque max 24.5 Nm (this value is hidden by the pop-up window in the image).

2. When you tap on the validation error icon next to the Torque max parameter, a short description of the error is given, saying that Target torque is greater than Torque max (Torque max <= Target torque).

3. To fix the error, adjust the Torque max value so that it is greater than Target torque, and the error icon will disappear.

Multistep Programs

WARNING

Risk of injury

A change in the configuration of the tightening program may cause unexpected torque, rotational direction, or speed in the system(s) where the tightening program is currently in use. This could result in severe bodily injury and/or property damage.

• Check the tightening program configurations after adding a new program or after applying changes to an existing program.

Controller features, such as the Low Reaction Tightening Strategies and controller-wide functions among others, require licenses distributed through the Functionality Management System (FMS). Whereas configuration of features is possible without specific licenses, the assignment and use of those features will require the correct license to be installed on the controller. Please refer to Licenses (FMS) for more detailed information on licenses.

A multistep tightening is a tightening done in several steps. The number of steps and the type of steps vary depending on the tightening to be done. A multistep tightening program is highly configurable, including monitoring function and restrictions.

Multistep GUI Interface

Multistep tightening programs can only be edited in the web GUI.

The interface for mutistep programs can be divided into three main areas.

On top there is a drop-down menu containing the Properties of the multistep tightening program. Here general properties such as program name, overal program monitor and validation can be filled out.

To the right there are four tabs containing the steps, monitors, restrictions and reporters that can be used to build the multistep program. To use any of the items, click on the appropriate tab, and drag the item in the list to the tightening area. Depending on its funtion, either drop the item between the beginning and the end of the program (for steps), or on top of a particular step (for monitors and restrictions).

The main area of the interface is the tightening area. This is the area that includes all the steps in the tightening program. Scroll the mouse wheel to zoom in and out on the tightening area.

At bottom left of the screen there is a Copy Tightening Program button and a Delete Tightening Program button.

Tightening Steps

This section lists the available tightening steps.

General Parameters

Name

It is possible to rename each step, if needed.

Rotational direction

Each of the tightening steps can run either forward, that is to make a tightening, or reverse, to loosen the screw slightly. The arrows indicate this direction. Many of the tightening steps have a direction hard-coded to forward, for example Tighten to Angle, or Tighten to Torque. Steps such as Loosen to Angle or Loosen to Torque have their direction automatically set to reverse.

The reverse setting is not allowed for tools configured with Gear Front Attachment (GFA) of type open end. The tightening direction of the tightening program must be the same as the tightening direction of the open end tool for a tightening to be allowed to be run. It is possible to assign a loosening program to a tightening program for an open end tool, but if the direction switch is set to run the loosening program, the tool will be locked.

Step category

For each step, there is an option to choose step category. By selecting step category, the NOK tightenings will be listed in the event result view with related detailed status together with the corresponding multistep error information. If no selection is made, the detailed status will be set to "uncategorized multistep error". The related detailed status can be customized.

Angle window

A joint is considered Hard if the screw is tightened to its full torque, and it rotates 30 degrees (or less) after it has been tightened to its snug point. A Soft joint rotates 720 degrees or more, after it has been tightened to its snug point. The hardness parameter defines the Angle Window for the gradient calculation. The harder the joint - the smaller the angle window.

Speed Ramp / Acceleration (only available in ToolsTalk 2)

For most of the steps, it is possible to specify how the acceleration to the target speed should be achieved. Three different settings are possible; Hard, Soft and Manual. The acceleration defined will be used whenever a step is started. Regardless whether the tool is already running with speed at the beginning of the step, the ramp will be used to accelerate to the target speed of the step. This process is the case even if the speed at the start of the step is higher, or lower than the target speed.

Speed ramp - Hard and Soft mode:

Speed ramp - Manual mode:

Using speed shifts

You can define 1-5 angle triggers or torque triggers during a step, where the speed will shift.

The speed shifts can be added in the Configuration field.

Within one step, all the speed shift triggers are based on the same property (either torque or angle). They cannot be mixed within one step.

To add a speed shift:

The Torque triggers and Angle triggers must be less than the step target, depending on the type of the step and the trigger type.

The Torque trigger and Torque speed also validate against the Max torque and Max speed of the tool.
A warning or error indicator occurs whenever the Speed Shift settings exceed either the tool max values or step max values.

Controlling braking behavior (Ergo stop/Inertia)

The braking behavior of a Multistep tightening program can be controlled at two possible locations in the program: in a step preceding a reversal of direction of the tightening, and/or at the final step of the tightening program. At other locations in the Multistep program, the braking parameters will not be available in the step's general settings. Braking can be set to either Ergo stop or Inertia. Inertia will brake the tool completely, while Ergo stop will allow for a more ergonomic slowing down of the tightening.

To set the type of braking, go into the settings for the step, and set the Brake configuration drop-down to Ergo stop or Inertia. Inertia has no additional parameters.

Ergo stop parameters

List of individual steps

The following tightening steps are not supported for tools configured with Gear Front Attachment (GFA) of type open end:

• A - Loosen to Angle

• TrR - Loosen to Trigger Release

• T - Loosen to Torque

• E - Engage

• SR - Socket Release

• DT - Tighten to DynaTork

• TP - TensorPulse

C - Clutch

This step will run the tool with the programmed Speed in forward direction until the Clutch has been released. When the tool has reported the release of the Clutch the step will finish with OK status.

A tightening program using the Clutch step cannot have any other step assigned.

This step is only valid for the Clutch tools BCV-RE and BCP-RE.

CL - Clutch Loosening

This step will run the tool with the programmed speed in reverse direction until the tool trigger is released.

A loosening program using the Clutch step can not have any other step assigned.

This step is only valid for the Clutch tools BCV-RE and BCP-RE.

W – Wait

In this step the tool waits until the Wait Type condition is fulfilled. The tool does not rotate while waiting, but Hold condition can be specified.

SR - Socket Release

This step runs the tool with speed n in the backward direction until the target angle is reached. The target angle is measured from the start of the step.

This step is only allowed to use as the last step in the tightening path of a multistep tightening program. However, it is possible to add a sync point after this step.

DI – Run Until Digital Input

This steps runs the tool, in the direction defined by parameter Direction, until the input specified by Digital Input goes high or low depending on the value of Stop Condition.

This step is not available for STB tools.

A – Tighten to Angle / Loosen to Angle

A – Tighten to Angle

This step runs the tool until the target angle is reached. The target angle is measured from the start of the step.

A – Loosen to Angle

This step runs the tool with the speed n in the backward direction until the angle target is reached. The target angle is measured from the start of the step.

TrR – Loosen to Trigger Release

This step is not available for Power Focus 6000 StepSync, Power Focus 8 StepSync, Flex.

This step runs in the backward direction until the tool trigger is released (loosen). It can only be used as a last step in a program.

For STB tools, this step is only applicable for loosening programs.

TTTR – Tighten to Trigger Release

This step runs until the tool trigger is released (tighten). It can only be used as a last step in a tightening program.

Tighten to Yield, Method 2 (YM2)

This step runs the tool with the specified speed in the forward direction until the yield point is detected.

Search for the yield point starts when the torque has reached Tt. The average of the torque over Af degrees is calculated. This procedure is repeated N rs times.

A reference slope is calculated with linear regression over the N rs points. After that, new average values are continuously calculated over A f degrees.

The actual slope is calculated with linear regression over the last N s average points. The yield point is reached when the slope is less than Py % of the reference slope.

T - Tighten to Torque / Loosen to Torque

T – Tighten to Torque

This step runs the tool with the programmed speed in forward direction until the target torque is reached.

T – Loosen to Torque

This step runs the tool with the speed in the backward direction. For the step to be active, the torque must first exceed 110 % of the Target torque. The Target torque should be set to a positive value. After reaching the target torque, the step runs until the torque drops below the target torque.

T+A – Tighten to Torque Plus Angle

This step runs the tool until the target torque is reached. From this point it continues to run an additional target angle.

T|A – Tighten to Torque or Angle

This step runs the tool with the speed n in the forward direction until the first of either torque target or angle target is reached. The torque and angle measurements start at the beginning of the step.

T&A – Tighten to Torque and Angle

The tool runs until with the specified speed in the forward direction until both target torque and target angle are reached. The target torque and the target angle must be set to > 0.

DT – Tighten to DynaTork

This step runs the tool with speed n in the forward direction until the Target torque is reached. The tool will then hold the current constant at the DynaTork Percentage of Target torque during the DynaTork time.

To avoid overheating of the tool, it is strongly recommended to never run DynaTork to more than 40% of the maximum torque of the tool.

Y – Tighten to Yield

This step is not available for STB tools.

This strategy runs the tool with the speed in the forward direction until the yield point is detected. The yield point is found by monitoring the torque gradient from the point where the torque goes above the Trigger Torque level, calculated based on Torque and Angle distance measurements. The Angle distance parameter is set according to the specified hardness of the joint.

Set the Gradient angle window (for hard joint, for soft joint or for manually setting of the Angle window). If Manual is selected, the Angle Window must be set. A joint is considered Hard if the screw is tightened to its full torque and it rotates 30 degrees or less after it has been tightened to its snug point. A Soft joint rotates 720 degrees or more after it has been tightened to its snug point. The hardness parameter defines the Angle Window for the gradient calculation. The harder the joint - the smaller the angle window.

ThCT – Thread Cutting to Torque

The Thread Cutting to Torque function enables tightening where the Rundown torque required is greater than the Rundown complete torque, for example when tightening thin layers of metal using self-threading (or self-tapping) screws. The tool runs in forward direction until the Thread Cutting Angle (Aw) is reached. The thread cutting angle window is measured from when the torque passes Thread Cut Trigger Torque (Ttc) for the first time. From the point where Thread cutting angle is reached, the step continues to run until the Target Torque (Tt) is reached.

RD – Rundown

This step is not available for STB tools.

Rundown step is the part of the tightening from when the screw enters the thread until just before the screw head touches the underlying surface and snug point is reached. The torque required during rundown does not contribute to any clamping force.

This step runs the tool with the speed in the forward direction, and depending on the Rundown Type, Torque or Snug the step behavior is as follows:

Rundown Type: To Torque: The step stops when the specified target torque is found.

Rundown Type: To Snug: The snug gradient calculation starts at the specified torque trigger level Tt. If no torque trigger is set the gradient calculation is started at the start of the step.

The slope calculation is made between two angle points A_d degrees apart and is calculated as: (Tn – Tn-1) / (An – An-1) and as soon as two slopes after each other are larger than TSLOPE the snug point is found.

E - Engage

This step is not available for STB tools.

This step runs the tool in both directions until the socket engages the screw. The step continues until Target torque or Target angle is reached, provided that Continue if not Engaged is set to Yes. If Target Angle is reached in any direction, the direction is reversed. Limit the search iterations by entering Max Engage Attempts. If Target Torque is reached in any direction the step will finish with OK status.

Ext - External Result

External result is a strategy used when an OK tightening is indicated by an external digital signal (and not by torque or angle values measured during tightening). This external signal can be provided through any means that can provide a digital signal into the controller (e.g through the I/O bus).

When the signal is sent, the result view (logged data) will show the value of the Target parameter provided in the tightening program (specified torque value, angle value, or text string). These (torque and angle) values do not represent actual measured values, but only inserted text.

TC - Torque Calibration

The Torque Calibration step is not supported for Power Focus XC.

This step is only supported for dual transducer tools.

The Torque Calibration step runs the tool with the specified speed in the forward direction until the torque target is reached.

MWR - Mechatronic Wrench

Mechatronic Wrench is a specialized step that can be used only in conjunction with the Mechatronic Wrench (MWR).

This step cannot be used in combination with other steps. No restrictions can be used with this step. By default, the step has three monitors: Peak Torque, Angle, and Click.

WP - Wrench Production

Strategy used for the quality test of the tightening performed with the STwrench.

Based on the control strategy selected, a combination of some of the parameters listed below will be displayed.

WQ - Wrench Quality

Strategy used for quality test of tightenings with the STwrench.

Based on the control strategy selected, a combination of some of the parameters listed below will be displayed.

TP - TensorPulse

Before using TensorPulse tightening step, it is mandatory that the following license type is installed on the controller:

• Low Reaction Strategies

TensorPulse is valid only for the following tools: ETV-STR61-100-13, ETV-STR61-70-13, ETV-STR61-50-10.

This step generates tightening pulses in the forward direction, until the torque target is reached.

If running TensorPulse tightening step, use the necessary PulseDrive socket/adapter.
If TensorPulse tightening step runs without the PulseDrive socket/adapter, all the tightenings are NOK. The step error “PulseDrive socket/adapter not detected” shows for no PulseDrive socket/adapter.

In the trace, the angle reversal means that the tool rotates backward to enable pulsing, but the bolt head does not necessarily rotate backward because of the PulseDrive socket/adapter.

Trace Setting

When the trace configuration is enabled on the program level, the trace resolution can be configured on step level. The setting for Trace Setting defines how the sampling should be done on each specific step.

With this trace recording the sample rates are not the same in all the steps, instead the sample rate depends on the configuration in each step. This means the trace is divided into one trace for each step.

The maximum number of samples in a trace is 4096. If a tightening produces more than 4096 samples a down-sampling process will take place. A down-sampling process is removing every second trace sample from the whole tightening and continuing recording with half the resolution. This process is repeated every time the 4096 sample limit is reached. Since the down-sampling process is done for all steps, the relation between the steps is the same.

Step Monitors

The step monitors are used to verify that the tightening was achieved according to the specification, for example, angle limits or torque. Each step has mandatory step monitors and optional step monitors. The mandatory monitors are included when dragging a new step to the multistep program. The optional monitors are flexible and can be placed as needed in the multistep program. Every step can have up to eight monitors each.

The following monitors are automatically added to every step that is added to the multistep tightening program.

A – Angle

This step monitor measures the maximum angle reached during the monitor and checks that it is between High limit and Low limit. The angle measurement starts at the start of the monitor or, if specified, at the point where the torque passes Trigger torque for the first time during the monitor.

YA – Angle from Yield

This step monitor is not available for STB tools.

This monitor measures the peak angle reached from the yield point and checks that the peak angle is within the limit.

C – Current

This monitor measures the actual current at any point after the torque passes Torque Trigger. The result will be the first peak or low value, that made the monitor NOK. In case of OK, the result will be the last measured current value. If the torque trigger is never reached during the monitor it will end with NOK status and no measurement value.

MT – Mean Torque

This step monitor is not available for STB tools.

This monitor measures the average torque during the monitor and checks the calculated value is within the limits.

PT – Peak Torque

This step monitor measures the maximum torque reached during the monitor, including any over shoot, and checks that it is between High limit and Low limit.

PTCA – Post Thread Cut Angle

Measures the angle achieved during the monitoring and checks that it is between the specified angle limits. The Trigger Torque level is ignored until the end of the Thread cut angle window is reached. After that, the angle measuring starts as soon as the measured torque is above Trigger Torque. The parameter Stop Condition specifies where the angle measurement should end.

PTCPT – Post Thread Cut Peak Torque

Measures the maximum torque achieved during the monitoring, including any over-shoot, and checks that it is between the Torque limits. All torque values are ignored until the end of the Thread cut angle window has been reached.

PVTH – Post View Torque High

This monitor checks that all torque values in the Angle Window Length are below the High limit.

The Angle Window starts at the angle degrees set in Start Angle in reverse direction from the shut-off point. This then spans for the angle degrees set in Angle Window Length in reverse direction. If Start Angle is left blank, the Angle Window starts at the shut-off point. The torque values used in the monitor are based on the mean torque value, calculated over Number of Samples. If the total angle of the step is less than Start Angle plus Angle Window Length the monitor will report NOK.

PVTL – Post View Torque Low

Same as monitor Post View Torque High, but this monitor checks that all torque values in the Angle Window Length are above Low Limit instead.

PrT – Prevailing Torque

The monitor calculates the prevailing torque value in the Window Length and checks that it is between the Torque limits. The Angle Window starts at the angle degrees set in Start Angle in reverse direction from the shut-off point. This then spans for the angle degrees set in Angle Window Length in reverse direction. If Start Angle is left blank the angle window starts at the shut-off point. The calculated prevailing torque value is the mean or peak torque value (depending on the parameter set by the user) during the Window Length. The calculated value is saved as result data Prevailing Torque Measured. If Torque compensation is set to On, the Prevailing Torque Measured will be subtracted from all torque result values in consecutive steps. Any previously calculated prevailing torque compensation values will no longer be subtracted from torque result values. If Torque compensation is set to No, no subtraction will be made in consecutive steps.

If the total angle of the step is less than the Start Angle plus Window Length, then the monitor will report NOK.

Prevailing torque can be measured as an average of measured values, or at peak torque. To choose between these two modes, set the Use Value parameter to either Mean torque (for average values), or Peak torque (for peak value).

PC - Pulse Count

This step monitor is only available for the following tools:

• ETV-STR61-100-13

• ETV-STR61-70-13

• ETV-STR61-50-10

Before using the Pulse Count step monitor, the Low Reaction Strategies license must be installed on the controller.

This monitor measures the number of pulses and confirms if it is between the pulse count low limit and pulse count high limit.
If the torque trigger level is set, the check starts as soon as the measured torque is above the torque trigger level.

If running a tightening step with Pulse Count step monitor, use the necessary PulseDrive socket/adapter.
If the tightening step runs without the PulseDrive socket/adapter, all the tightenings are NOK. The step error “PulseDrive socket/adapter not detected” shows for no PulseDrive socket/adapter.

SOT – Shut Off Torque

The shut off point is the point where the step reaches its target. The torque is measured at the shut off point and checked to be between High limit and Low limit.

SOC – Shut Off Current

The shut off point is the point where the step reaches its target. The current is measured at the shut off point and checked to be between High limit and Low limit .

SSD - Stick Slip Detection

This step monitor detects and reports stick slip effects during a step. The detection is done by counting the number of times the torque falls below the Trigger Level. If the number of times is larger than Maximum Number of Oscillations then the stick slip error is reported. The monitor operates in two different modes, Dynamic or Fixed. The difference between the modes is the way that the Trigger level is calculated.

Dynamic Torque: Trigger Level is dynamically calculated as Peak Torque Percentage of the current max torque, which has been achieved so far during the monitoring. The monitoring is started as soon as the torque passes the Trigger Torque.

Fixed Torque: Trigger Level is the fixed Trigger Torque specified by the user. In this mode the percentage is not needed.

If the torque never reaches the Trigger Torque then the monitoring is not started, this will result in status NOK.

Ti – Time

Measures the elapsed time during the monitor and checks that it is between the time limits. The time measurement starts at the start of the monitor and, if the Trigger Torque is specified, at the point where the torque passes Trigger Torque for the first time during the monitor.

TG – Torque Gradient

This monitor checks that the gradient is within the limit.

TC – Torque Calibration

This step monitor is only available for tools equipped with dual transducers.

The Torque Calibration monitor checks if the maximum torque reached is within the torque limits.

TAW – Torque in Angle Window

This monitor checks that all torque values in the angle window are within the torque limits.

TRD – Torque Rate and Deviation

This step monitor measures and checks the torque rate, i.e. the ratio of torque vs. angle. The calculated torque rate is checked if it is within the torque rate limits defined by High Limit and Low Limit.

Cl – Click

This step monitor is not available for IxB tools.

Monitor to enable click torque and click angle results. This monitor has no settings, and can only be used in conjunction with the MWR step.

LD - Loosening Detection

This step monitor is only available for STwrench tools

This monitor can be used to check the torque and direction to see if a loosening is attempted when using the Wrench Production step strategy for an STwrench. If the applied torque is above the value set for Loosening Limit in the direction opposite to the configured thread direction of the program, the result shall be reported as NOK.

Step Restrictions

To make sure the tightening stops if something unexpected happens, it is possible to add step restrictions to the multistep tightening program. These restrictions could, for example, test that a maximum torque is not reached or that a part of the multistep tightening does not take too long to run. Each step has its own set of mandatory step restrictions and optional step restrictions. The mandatory restrictions are included when dragging a new step to the multistep program. All steps can have up to four restrictions each.

In Power Focus 6000 StepSync and Power Focus 8 StepSync controllers, it is possible to use synchronization points in the tightening program. When any condition that is set for a restriction is met, the tool will be stopped immediately and the program jumps to the next synchronization point (only valid for the Power Focus 6000 StepSync, Power Focus 8 StepSync and Flex), or the end of the program. In controllers without StepSync the tool is stopped immediately and the program jumps to the end of the program.

For Flex only:

For each restriction, select Repairable = Yes to allow retry when tightening stops.
