Internal Regeneration Capability
The drive/controller may experience an over-voltage fault if the regeneration exceeds the absorbent capacity of
the drive/controller’s internal bus capacitors, as shown in the following table.
The available absorption varies, based on mains voltage and the drive/controller’s internal capacitance. The various
drives can absorb the following amounts of regenerated energy in its internal capacitors.
