Fault Code Meanings and Handling Methods for Inovance Servo IS620P Series

Fault Code er.630

Meaning

The er.630 fault code indicates motor stall overtemperature protection. When the motor stalls due to excessive load or mechanical obstruction during operation, and the motor temperature rises to a certain level, the servo drive will report this fault.

Solution

  1. Check Mechanical Load: Confirm whether there is any obstruction or excessive load in the mechanical part and address it promptly.
  2. Adjust Gain Parameters: Adjust the speed loop and position loop gain parameters according to the mechanical load to prevent the motor from stalling due to excessive gain.
  3. Increase Acceleration and Deceleration Time: Increase the settings of H06-05 and H06-06 to make the motor start and stop more smoothly, reducing the possibility of stalling.
  4. Check Motor and Drive Connections: Ensure that the connections between the motor and the drive are correct to avoid stalling caused by wiring errors.
  5. Monitor Motor and Drive Status: Use the Inovance drive debugging platform to monitor the motor’s operating status and the drive’s output commands to identify any anomalies.
