Reversing
A dynamic brake may be used when reversing the motor direction
(Figure 20). For the RUN/BRAKE switch, use a four pole, three
position switch rated for at least 125 VDC, 6 Amps. The dynamic
braking resistor should be ceramic encased, and a minimum of
25W, 10 watts. The motor stops less rapidly with higher brake
resistor values. Wait for the motor to stop completely before
switching it to either the forward or reverse direction.
