Cause : Output current overload timed out (I2 t) comes when the It.Ac trip indicates a motor thermal overload based on the Motor Rated Current (Pr 05.007) and Motor Thermal Time Constant (Pr 04.015). Pr 04.019 displays the motor temperature as a percentage of the maximum value. The drive will trip on It.AC when Pr 04.019 gets to 100 %.
- Ensure the load is not jammed / sticking.
- Check the load on the motor has not changed.
- Tune the motor rated speed parameter (Pr 05.008) (RFC-A mode only).
- Ensure the motor rated current is not zero.
