Cause

1. Servo motor UVW wiring;
2. Servo drive gain too low;
3. Position command pulse frequency too high;
4. Excessive position command acceleration;
5. Position deviation exceeds the excessive position deviation fault value (P00.19), whose setting is too low;
6. Servo drive/motor fault;
7. Brake release abnormal; motor stalled or driven by external force, such as mechanical jamming, collision, gravity, or another external pulling force.

Corrective action

1. Verify the motor main circuit cable wiring and reconnect it;
2. Check whether the servo drive gain is too low and increase it;
3. Try reducing the command frequency before running again; reduce position command frequency or acceleration, or adjust the electronic gear ratio;
4. Reduce command acceleration before running again; add smoothing functions such as position command acceleration/deceleration time parameters;
5. Check whether the position deviation fault value (P00.19) is appropriate and set (P00.19) correctly;
6. Inspect the operating graph in the background software; if there is input but no feedback, replace the servo drive
7. Check the wiring and brake power supply, confirm that the brake is normal, and confirm that the motor is neither stalled nor driven by external force.
