R =Minimum brake resistance that can be used with this frequency converter. If the frequency converter includes multiple brake choppers, the
min
resistance value is the sum of all resisters in parallel
R =Nominal resistance required to achieve 150% braking torque.

1) Larger frequency converters include multiple inverter modules with a brake chopper in each inverter. Connect equal resistors to each brake
chopper.
