9.5 - Loosening - torque control and angle
monitoring
Loosening with torque control is used when you want to
maintain small constraints in the assembly.
The un-tightening operation is not complete.
In addition to monitoring the untightening of the fastener,
the system monitors the number of degrees reached
while maintaining a residual torque in the fastener.

9.6 - untightening - angle control and torque
monitoring
Loosening with angle control is mainly used to release
the constraints in the assembly completely.
The recorded values are the following:
final torque and final angle.
Spindle stop
● IF angle ≥ target angle
● OR torque > safety torque
Accept report
● IF torque < safety torque
● AND min. torque ≤ final torque ≤ max. torque
● AND min. angle ≤ final angle ≤ max. angle
