Soft Phase Alarm

What does SP0134 mean?

An abnormal acceleration rate has been detected in the spindle motor. This indicates that the motor is accelerating too rapidly or outside its expected operational limits.

• Inconsistent or erroneous phase information from the motor controller.
• Faulty motor position sensor (e.g., Hall effect sensor, encoder).
• Incorrect motor winding configuration or connection.
• Software error in the drive's phase detection algorithm.
• High motor currents causing internal control instability.

Click steps to track your progress.

1. 1

   Review the spindle acceleration parameters (e.g., in parameter manual B-65280EN/06). Adjust if necessary.

2. 2

   Monitor the motor's acceleration profile during operation using diagnostic tools.

3. 3

   Check for mechanical issues like excessive load or binding that could cause abnormal acceleration.
