What does 84 mean?

This fault indicates that the motor utilization is too high, meaning the motor is operating under excessive load. This condition can lead to motor overheating and premature failure if not addressed. The inverter initiates an emergency stop to protect the motor.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Ensure adequate pause times are observed between motor operations to allow for cooling and prevent cumulative thermal stress.

2. 4

   Verify motor thermal model settings in the inverter match the connected motor's characteristics.
