Step Parameters
The following step parameters are common for many of the step types. The parameters are set in the step properties window which is displayed when selecting a step in the tightening program.
Parameter | Description |
|---|---|
Name | Name of the step. |
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 a 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 will be the case even if the speed at the start of the step is higher, or lower than the target speed. |

Using speed shifts | 1−5 angle triggers or torque triggers can be defined during a step, where the speed will shift. Within one step, all the speed shift triggers are based on the same property, that is either torque or angle. They cannot be mixed within one step. 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. 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. It is possible to push the settings to the tool when a tightening program has a warning, but not when a tightening program has an error (fault) indicator. |
Brake type | 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 tightening 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. Inertia has no additional parameters. Ergo stop parameters:
