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