27Application Notes
Use a single-pole, three-position switch with a single speed adjust
potentiometer to coast to a stop between reversals (Figure 8). Set
the switch to the center position to decelerate the motor to a stop.
The switch contacts should be rated at a minimum of 125 volts
and 150% to 200% of motor nameplate current.

Warning
Do not change the FORWARD/REVERSE switch setting
while the motor is still running. Plug reversing the motor
(not allowing the motor to come to a stop before reversing)
will cause excessively high currents to flow in the armature
circuit, which can damage the control and/or motor.
