DC BUS over-voltage during acceleration

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.
