Table 5.10 Brake Chopper Data 525–690 V
R
min
=Minimum brake resistance that can be used with this adjustable frequency drive. If the adjustable frequency drive 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.
R
rec
=Resistance value of the recommended Danfoss brake resistor.
1)
Larger adjustable frequency drives include multiple inverter modules with a brake chopper in each inverter. Equal resistors should be connected
to each brake chopper.
