9.3 Torque Over Abnormals
9.3.1 Code 2-1 TORQUE OVER ABNORMAL / TORQUE INHIBIT HIGH LIMIT.
High torque was detected during the Torque Inhibit Function which was greater than the Torque
Inhibit High Limit parameter.
The cause of this abnormal is;
1. Torque Inhibit High Limit parameter set too low for application.
2. Initial starting torque is too high for size of tool. (If limit is set at full scale torque)
3. Excessive binding of output shaft or driver during Torque Inhibit.
RECOVERY:
1. Raise Torque Inhibit Limit.
2. Check that the tool has no external force applied to it.
3. Verify that the torque required is not more than tool capability.
4. Verify that nothing is binding on the output shaft of the tool while it begins its cycle.
