Impulse Single-Step Tightening Stage Parameters

Parameter name

Condition

Description

Default value

Pulse Energy

The Pulse energy delivered in the action pulse expressed in a percentage of the maximum energy the tool can deliver in each pulse.

100%

Residual torque correlation factor

The term Residual torque correlation factor is similar to a calibration and adjusts between the dynamic torque, measured in the electrical tool, and the residual torque, measured by a control tool.

100%

Premature torque loss detection time

A constant increase in torque is assumed when moving from rundown to tightening. A socket slip of, or a broken screw head can cause the torque decrease. This may be detected in a monitoring window.

200 ms

Target torque

Final target torque for the tightening.

0 Nm

Torque limits

Selected by radio buttons.

Limits can be Automatically or Manually selected

Manually

Torque min

Torque limits = manual

Minimum torque for the step.

0 Nm

Torque max

Torque limits = manual

Maximum torque for the step.

1 Nm

Angle limits

Off:Angle limits is turned off.

From Rundown complete: Angle limits is turned On. The system starts to monitor the tightening angle as soon as Rundown complete is reached and reports if angle limits are violated.

From torque: Rundown angle limits is turned On. The system starts to monitor the tightening angle from the specified torque value and reports if angle limits are violated.

Off

Final angle monitoring torque

Torque value from where Angle limits monitoring starts.

20 Nm

Angle min

Angle value for lower angle limit from the starting point.

Angle max

Angle value for the upper angle limit from starting point.

Time limits

Selected from a shortcut menu:

Off:Time limits is turned off.

From rundown complete: Time limits is turned On. The system starts to monitor the time as soon as rundown complete is reached and reports if the time limits are violated.

From torque: Time limits is turned On. The system starts to monitor the time from the specified torque value and reports if the time limits are violated.

Off

Time monitoring torque

Time limits = from torque

Torque value from where the Time limits monitor starts.

Time min

Time limits = On

Minimum allowed time for tightening.

10ms

Time max

Time limits = On

Maximum allowed time for tightening.

1000ms

Pulse limits

Selected from a shortcut menu:

Off: No pulse limit monitoring.

From rundown complete: The monitoring starts when the Rundown complete torque is reached and reports if the number of pulses is outside the limit.

From torque: The monitoring starts when the specific torque value is reached and reports if the number of pulses is outside the limit.

Off

Final pulse monitoring torque

Pulse limits = from torque

Torque value from when the pulse limits are monitored.

18.75 Nm

Pulses min

Pulse limits = on

Minimum number of pulses to reach the final target.

2

Pulses max

Pulse limits = on

Maximum number of pulses to reach the final target.
