Motor underload

Hva betyr 17 ?

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.

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.
