7-3-4 Torque Inhibit Check
The Torque Inhibit Check is used to ignore high torque spikes during initial starting of the motor or
fastening process. Under normal fastening operations Peak Torque will stop the fastening process (if
Standard Torque is reached). This may not be desirable for applications with high starting torque and
lower fastening torque. Applications such as self tapping screws, nylok nuts, crushed fasteners and
application with high starting inertia may require this function.
Torque Inhibit is set by the angle that is required to be “ignored” during the process. The Torque Inhibit
Limit is a torque limit used as protection in case the amount of torque monitored during the Torque Inhibit
Angle is too high. If this torque limit is hit during the Torque Inhibit process, then the spindle will stop and
an Abnormal is output.

7-3-5 Break Away Torque Check
A Break Away Torque Check can be set to check the reverse torque on all reversing functions (whether a
reverse operation or part of an optional pre or post fastening operation). If the Reverse Torque Limit is
exceeded the reverse operation will stop and an Abnormal will be generated.

Note: Reverse Torque judgment is done only by using Reverse 2 or Reverse 3 (from Sequence) or by the
fastening option “Reverse Before Fastening”. No Judgment will be made on Manual reverse
operations.
