Options can be ordered as factory built-in options. For information on serial communication bus and application option compatibility with older
software versions, contact the Danfoss supplier.

Brake Resistors
The requirements for brake resistors vary in different applications. Always consult the VLT FC Series Brake Resistor Design
Guide before selecting brake resistors. Critical data includes:
•
Brake duty cycle, resistance and brake resistor power capability
•
Adjustable frequency drive minimum resistance
The tables below present typical data for two common application types. 10% is typically used for occasional braking of
horizontal loads. 40% is typically used in lifting applications where the load must be stopped every time it is lowered.

=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.

=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.
