• Code A01-05 – TORQUE TRANSDUCER / CAL JUDGMENT ERROR
The System detected a Calibration Voltage error after a fastening START was attempted with the
Calibration Check function disabled.
CAUSE:
• When the tool torque transducer is sensing excessive torque due to pressure on the tool body
during a START signal to the controller (when tool normally should be in an idle state with no
external forces applied)
• The tool cable is disconnected or lost connection while a START was attempted.
• 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 the same time the
START signal is given to 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.
• Code A01-06 – TORQUE TRANSDUCER / STARTED ON ZERO ERROR CONDITION
The START signal was input while a Zero Check Abnormal (Code A01_3) condition existed.
RECOVERY:
1. Confirm the PLC logic disables the start signal during an existing abnormal condition or when not
ready. (An abnormal condition must be corrected and RESET before normal operation may
begin)
2. Follow the ZERO CHECK ERROR abnormal help procedure.
• Code A01-07 – TORQUE TRANSDUCER / STARTED ON CAL ERROR CONDITION
The START signal was input while a Cal Check Error (Code A01_4) condition existed.
RECOVERY:
1. Confirm the PLC logic disables the start signal during an existing abnormal condition or when
not ready. (An abnormal condition must be corrected and RESET before normal operation
may begin)
2. Follow the CAL CHECK ERROR abnormal help procedure.
