4 Dynamic Braking Kit for FlexPak Plus and MinPak Plus DC Drives
Step 6. For non-regenerative FlexPak Plus DC drives with a Reversing Contactor: Connect the dynamic
braking resistor between the corresponding normally closed ( NC ) contacts on the forward contactor
and the reversing contactor. For example, connect the resistor between terminal 8 on the forward
contactor and terminal 8 on the reverse contactor. This places the resistor across the motor’s
armature (A1 and A2) when both contactors are de-energized. Refer to figures 3 and 4.
