Thermal overload of motor

What does 84 mean?

The motor has experienced a thermal overload, or its internal winding thermostat (TH) has tripped. This can be caused by excessive load, high ambient temperatures, or incorrect drive configuration settings for motor protection.

• Motor operating under excessive mechanical load.
• High ambient temperature around the motor or insufficient cooling.
• Heat accumulation around the motor due to poor ventilation.
• DIP switch S1/5 not set to "ON" when the MOVIMOT inverter is installed close to the motor.
• Incorrect setting of DIP switch S1/6 for MOVIMOT and motor combinations with a lower power rating.
• Mismatch between drive and MOVIMOT frequency inverter, signaling error shortly after initial release.
• Motor temperature monitoring (TH winding thermostat) tripped when MOVIMOT extra function 5 is selected.

Click steps to track your progress.

1. 1

   If the MOVIMOT inverter is installed close to the motor, verify DIP switch S1/5 is set to "ON".

2. 2

   For MOVIMOT and motor combinations with one lower power rating, check the setting of DIP switch S1/6.

3. 3

   Reduce the ambient temperature surrounding the motor or improve cooling.

4. 4

   Prevent heat accumulation around the motor by ensuring adequate ventilation.

5. 5

   Reduce the mechanical load on the motor.

6. 6

   Increase the motor speed if appropriate for the application.
