Tightening
270 9836 3521 01
In order to create or second program with target torque 75 Nm we copy the Tighten program and change
the TargetTorque variable value to 75 Nm. The advantage with user variables is that each program need
only to expose a set of variables that are sufficient to change to adapt the program to other requirements.
Note! Complex expressions are not supported for user variables, one operation ( + , - , *, /) and one
parameter is allowed. Examples:
TargetTorque * 1,3
T 3

ocurred, for example a torque value has been reached.
