Motor underload

What does 17 mean?

The motor underload protection has tripped, indicating that the motor is operating with significantly less load than expected or specified. This can be due to a disconnected load, broken component in the mechanical system, or incorrect parameter settings.

• Motor current consistently below expected minimum.
• Low load or no load conditions (P1-08 < P1-09).
• Motor not connected properly.
• Faulty motor or winding.
• Incorrect current sensing parameters.

Click steps to track your progress.

1. 1

   Inspect the mechanical load connected to the motor for any disengagement, breakage, or abnormal reduction.

2. 2

   Verify that the process being driven by the motor is functioning correctly and demanding the expected load.

3. 3

   Review the motor underload protection parameters (e.g., minimum current threshold, delay time) in the frequency converter to ensure they are set appropriately for the application.
