Motor ETR Over Temperature

What does 10 mean?

The motor's Electronic Thermal Relay (ETR) has detected an over-temperature condition. This indicates the motor is running too hot, potentially causing winding insulation damage and reducing motor lifespan. The drive trips to protect the motor.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify motor thermal protection settings (Parameter 1-90) are accurately configured for the specific motor.

2. 4

   Measure actual motor winding temperature if possible, to confirm the ETR reading.
