Reversible Motor Starter Circuits for Changing the Rotational Direction of Three-Phase AC Induction Motors (Tip 10)
Category: Motor Control
Version 4.0. Updated 12/98
Special Hardware Requirements: None
Project Example .
This programming example shows how to control a three-phase induction motor with two possible rotational directions.
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.
