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.
4. Check whether the required brake power is
within the specified limits.
