Category: Warning

Cause

1. Servo motor U, V, W wiring is incorrect.
2. Servo unit gain is low.
3. The position command pulse frequency is relatively
4. Position command acceleration is excessive.
5. Relative to operating conditions, the excessive position deviation alarm threshold (Pn520)
6. Servo unit fault.

Corrective action

1. Check the motor and encoder cables for poor contact or other problems.
2. Increase servo gain using advanced autotuning or similar means.
3. Reduce position command pulse frequency or command acceleration, or adjust the electronic gear ratio.
4. Add smoothing using position command acceleration/deceleration time constants (Pn216/Pn217).
5. Set Pn520 correctly.
6. Supply power again. If the alarm persists, the servo unit may be faulty. Replace it.
