9.3 Torque Over Abnormals
9.3.1 Code 2-0 TORQUE OVER ABNORMAL / OFFSET TORQUE.
High torque was detected during an Offset Check Function which was greater than the pro-
grammed Offset Torque Limit.
The cause of this abnormal is;
1. Excessive binding in the spindle assembly or drive external to the square drive of the tool
assembly.
2. The tool transducer is sensing excessive torque due to pressure or vibration during the off-
set check cycle.
3. The controller or the transducer cable is located in an electric or magnetic noise field.
RECOVERY:
1. Repair or replace mechanism which is binding external to the square drive output of the
tool.
2. Check that the tool has no external force applied to it.
3. Verify that the cable or controller is not located near any high voltage transient power
sources. Relocate as required and reinitialize.
9.3.2 Code 2-1 TORQUE OVER ABNORMAL / TORQUE INHIBIT HIGH LIMIT.
High torque was detected during the Torque Inhibit Function which was greater than the Tor-
que 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.
