Category: Alarm
Cause
Condition: Abnormal communication when a Delta position signal interface box is connected to the CN2 interface. Causes:
- Abnormal communication with the position signal interface box.
- Abnormal communication during motor parameter identification wizard setup.
Corrective action
- Confirm that the position signal interface box wiring is correct.
- Check the detector, the drive CN2 connector, and the motor end for poor connections or broken/damaged cables. Replace connectors and cables if these conditions are found.
- Monitor the encoder communication error rate with P0.002 = -80. If this value continues to accumulate, interference is present. Check the following: (a) Verify that the motor grounding terminal is properly grounded; connect the power cable grounding conductor (yellow-green) to the drive heatsink (Heat Sink). (b) Verify that the encoder signal cable is normal and keep it separate from power supply or high-current wiring to prevent interference. (c) Check whether the position detector cable is shielded. If all checks above are complete but the alarm persists, replace the motor. Power on again to clear.
