Target Torque Limits

By setting the Target torque limits , it is possible to discard a tightening should the torque result not fall within the specified torque limits. A too high torque can cause the screw to deform as a result of passing the yield point, and can even break, or can cause the stripping of threads. Not enough torque result in the clamping force not being enough to withstand the forces for which the joint is designed.

Parameter

Description

Default value

Torque limits

The tightening is considered as NOK if the torque result is outside the range defined by Torque min and Torque max.

Auto: Torque limits are automatically set to the default values specified for Torque min and Torque max.

Manual: Enables the Torque limit values to be set manually.

Auto

Torque min

Torque value for lower torque limit. Can be entered if Manual has been selected.

95% of Target torque

Torque max

Torque value for upper torque limit. Can be entered if Manual has been selected.

120% of Target torque

The parameter Measure torque at can have different values. By default the torque is measured at torque peak. The possible values of the parameter are listed in the table below.

Name

Description

Max torque value

Measures the highest torque value during the tightening.

Value at peak angle

Measures the torque value at the highest angle value.

Value at shutoff

Measures the last torque value before entering the break step.
