Regen Resistors

Regeneration, or “shunting,” dissipates energy from the DC bus during deceleration of the motor load. If not dissipated, this energy is fed back into the drive and can cause an over-voltage fault. A regeneration resistor, or regen resistor, is an external device that dissipates excess energy and allows the drive to function normally when braking. Correct sizing of the resistor is crucial.

After you calculate the appropriate resistor size using our MOTIONEERING® application sizing and selection software, compare the results with the capabilities of the drive and select an external regen resistor which matches these capabilities from the chart below. The resistors shown below are included in the WorkBench setup. If you do not find a match for your application, please contact the Kollmorgen customer support team for further assistance.
