Motor over temperature

What does 16 mean?

The frequency converter's internal motor temperature model has detected that the motor is overheating. This fault primarily indicates that the motor is operating under an overload condition.

• Motor winding temperature exceeds limit.
• Overload condition sustained for too long (P1-07).
• Faulty motor temperature sensor (PTC or KTY).
• Inadequate motor cooling (e.g., blocked fan).
• High ambient temperature around the motor.

Click steps to track your progress.

1. 1

   Decrease the mechanical load applied to the motor.

2. 2

   If no motor overload is present, check and adjust the motor temperature model parameters within the frequency converter's settings (e.g., thermal time constant).
