Brake Relay to Motors Without Full Wave Rectifiers
When using Parker MaxPlus motors, Parker motors with serial numbers less
than 010904xxxxx, or non-Parker motors, you must install a fly-back diode.
Consult the specifications or the manufacturer of your motor.
1. Connect one red/blue brake wire (Parker Motor cable or equivalent) to
one BK terminal (located on the Motor connector.
2. Connect the second red/blue brake wire (Parker Motor cable or
equivalent) to the 24V return on your power supply.
3. Between the two red/blue wires, connect the fly-back diode.
4. Connect the +24 VDC power supply to the second BK terminal.
Figure 21 shows a typical installation.

Regeneration Protection
Drive/controller models AR-04CE, AR-08CE, and AR-13CE do not have
internal regeneration resistors for power dissipation; however, an external
regeneration resistor can be used for this purpose. For information on
selecting a suitable external regeneration resistor, see “Appendix B External
Powe
r-Dump Resistor Selection.”
Regeneration Connection
To use an external regeneration resistor, connect your external resistor to the
R+ and R- terminals located on the Control Power connector.
