650S AC Drive
External Brake Resistor
All 650S units are supplied without braking resistors. The dynamic brake switch terminals (where
fitted) allow easy connection to an external resistor. These resistors should be mounted on a
heatsink (back panel) and covered to prevent injury from burning.
Recommended Brake Resistors
The following brake resistors are available from Parker SSD Drives:

Alternative Brake Resistor Selection
Brake resistor assemblies must be rated to absorb both peak braking power during deceleration and the average power
over the repeated cycles.
