Over voltage
The DC bus voltage has exceeded its maximum allowable value.
1. Check if the input voltage falls within the rated AC motor
drive input voltage range.
2. Check for possible voltage transients.
3. DC-bus over-voltage may also be caused by motor
regeneration. Either increase the Decel. Time or add an
optional brake resistor (and brake unit).
4. Check whether the required brake power is within the
specified limits.
