Regen Resistor Wattage

Converting this energy into wattage can allow the rating of the regen resistor to be analyzed. The unit of

Joule is converted to wattage by dividing by the duty cycle of the overall motion profile.

Watts =

Where:

is the motion profile duty cycle, in seconds.

The peak wattage rating of the regen resistor is determined simply by dividing the square of the DC bus

overage specification by the resistors ohm value:
