Motor over temperature

Hva betyr 16 ?

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.

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).
