Cause : MOTOR CURRENT LIMIT comes when drive limits motor current according to current limit defined by parameter 20.03 MAXIMUM CURRENT.

The code 2300 in your ABB ACS800 drive indicates a motor current limit warning. This isn't necessarily a fault that will shut down the drive immediately, but it's a notification that the motor current is approaching or exceeding the limit set in the drive parameters.

1. Reduce load or increase ramp time.
2. Increase parameter 20.03 MAXIMUM CURRENT value.
3. Check Fault Function parameters.
