Braking Resistor Selection Tool

This calculator is currently compatible only with 400V-class drives and motors. It assumes a CDBR braking start voltage selection of 760V, factors in the tolerance of the resistors, and prioritizes the most cost-effective options.
The calculator also internally calculates the maximum braking time by multiplying the duty cycle with the duty cycle duration.

If these parameters do not suit your application, please refrain from using this tool.

Please select a drive.
The input value must be between 1 and 100.
The input value must be between 1 and 10000.
The input value must be higher than the "Braking Power" value and must between 0.01 and 1500.
The input value must be lower than the "Peak Braking Power" value and must between 0.01 and 1000.
