Reversible Motor Starter Circuits for Changing the Rotational Direction of Three-Phase AC


#1

Use the momentary contact switch at input I0.0 to start the motor counterclockwise. Use the momentary
contact switch at input I0.1 to start the motor clockwise. The prerequisites are that the motor circuit breaker
at input I0.3 and the OFF switch at input I0.2 are not activated. The rotational direction cannot be changed
until after the OFF switch is pressed and a waiting period of 5 s has elapsed. This allows the motor to brake
and start up in the opposite direction
