Low voltage
The AC motor drive detects that the DC bus voltage has fallen below its minimum value.
1. Check whether the input voltage is in the AC motor
drive rated input voltage range.
2. Check for abnormal load on the motor.
3. Check for correct input power wiring to R-S-T (for
three-phase models) without phase loss.
