DC bus over-voltage during acceleration
230V: 405 VDC ; 460V: 810 VDC
corrective action
1. Check if the input voltage falls in the rated AC motor drive input voltage range.
2. Check for possible voltage transients.
3. If DC bus over-voltage is due to regenerative voltage, increase the Acceleration Time or add an optional brake resistor.
