Motor Overload (I²t)

What does OC6 mean?

The motor has exceeded its thermal overload limit (I²t model), caused by excessive continuous current or frequent/prolonged acceleration cycles. This indicates the motor is either undersized for the application, or the drive parameters are not correctly configured. Continued operation under overload conditions will severely damage the motor windings.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify the motor's nominal current and overload settings (e.g., C0120) are correctly parameterized in the drive.
