Application Notes
DIRECTION switch
NOTE:
You may need to adjust the OFFSET trimpot when using
a DIRECTION switch in unidirectional mode.
Use a single-pole, single-throw switch with a single speed adjust
potentiometer to reverse a motor (Figure 16). Brake the drive
before reversing by using a RUN/BRAKE switch as shown.
Close the switch to regeneratively brake the motor to a stop at a
rate controlled by the DECEL trimpot. This will help prevent high
reversing currents from damaging the drive or motor.
