min
=Minimum brake resistance that can be used with this frequency converter . If the frequency converter includes multiple brake choppers, the
resistance value is the sum of all resisters in parallel
R
br, nom
=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.
