Motor Protection Trip

What does 84 mean?

Emergency stop because the motor utilization is too high, indicating that the motor is experiencing prolonged overload conditions. This trip protects the motor from thermal damage.

• Motor protection relay or internal drive protection has tripped.
• Motor overload condition causing thermal or current trip.
• Short circuit in motor windings or cabling.
• Ground fault detected in the motor circuit.

Click steps to track your progress.

1. 1

   Reduce the mechanical load on the motor to bring its utilization within limits.

2. 2

   Extend acceleration and deceleration ramps to reduce peak current demands on the motor.

3. 3

   Observe longer pause times between operations to allow the motor to cool down adequately.
