Motor stalled

What does 15 mean?

The motor stall protection has tripped, indicating that the motor has either stopped or is operating at a very low speed under a load that exceeds its capacity. This condition can lead to motor overheating and mechanical damage.

• Motor shaft rotation is blocked or severely restricted.
• Overly high starting torque demand.
• Mechanical binding in the driven equipment.
• Incorrect motor tuning parameters (P1-10 to P1-15).
• Low supply voltage affecting motor torque.

1. 1

   Inspect the motor and its driven load for any mechanical obstructions, binding, or excessive friction that would prevent free rotation.

2. 2

   Evaluate the mechanical load connected to the motor; reduce the load if it is exceeding the motor's rated capacity or the drive's settings.

3. 3

   Verify that the motor parameters (e.g., motor nominal current, stall time) are correctly configured in the frequency converter.
