DC BUS over-voltage in constant speed
1. Check if the input voltage falls within the rated AC motor drive input voltage range.
2. Check for possible voltage transients.
3. If DC BUS over-voltage due to regenerative voltage, please increase the Deceleration Time or add an optional brake resistor.
Check drive rectifier & IGBT using multimeter.
Check wiring.
Check drive hardware using multimeter.
