10-2 Torque Transducer Errors [A.01 - *]
•
Code A01-01 – TORQUE TRANSDUCER / ZERO MASTER ERROR
The System detected a Zero Level Check error during power on initialization.
CAUSE:
•
When the tool torque transducer is sensing excessive torque due to pressure on the tool body
during power on initialization (when tool normally should be in an idle state with no external
forces applied)
•
The tool cable is disconnected or lost connection during power on.
•
If the controller or the tool cable is located in an electric or magnetic noise field.
•
When the torque transducer, tool cable or the controller malfunctions.
RECOVERY:
1. Check that the tool has no external force applied to it (IE: anything touching the tool assembly,
misalignment, etc.). Also verify there is no excessive friction in the spindle assembly.
2. Verify that no excessive vibration or shock takes place on the tool mounting at power on of the
controller. (Vibration could be sensed by torque transducer)
3. Verify that the tool cable is securely connected at both ends and free from cuts, abrasive wear or
kinks
4. Verify that the tool cable or controller are not located near any high voltage transient power
sources. Relocate as required and reinitialize.
5. Turn control power off to the unit for at least 5 seconds then re-apply power
6. Exchange tool cable, tool and/or controller with known working units. Reinitialize the system after
each exchange to determine which component may have caused the failure (abnormal).
7. Replace the defective component.

Code A01-02 – TORQUE TRANSDUCER / CAL MASTER ERROR
The System detected a Calibration Voltage Check error during power on initialization.
CAUSE:
1. When the tool torque transducer is sensing excessive torque due to pressure on the tool body
during power on initialization (when tool normally should be in an idle state with no external
forces applied)
2. The tool cable is disconnected or lost connection during power on
3. If the controller or the tool cable is located in an electric or magnetic noise field.
4. When the torque transducer, tool cable or the controller malfunctions.
RECOVERY:
1. Check that the tool has no external force applied to it (IE: anything touching the tool assembly,
misalignment, etc.). Also verify there is no excessive friction in the spindle adapter.
2. Verify that no excessive vibration or shock takes place on the tool mounting at power on of the
system. (Vibration could be sensed by torque transducer)
3. Verify that the tool cable is securely connected at both ends and free from cuts, abrasive wear or
kinks
4. Verify that the tool cable or controller are not located near any high voltage transient power
sources. Relocate as required and reinitialize.
5. Turn control power off to the unit for at least 5 seconds then re-apply power
6. Exchange tool cable, tool and/or controller with known working units. Reinitialize the system after
each exchange to determine which component may have caused the failure (abnormal).
7. Replace the defective component.
