6.2.4 Example: Run forward/Run reverse/stop (status-controlled)
The "Run" funcon automacally becomes a "start enable" if the funcons "Run
forward (CW)"/"Run reverse (CCW)" are connected to triggers.
This example shows a status-controlled start/stop via three switches:
•
Switch S1 enables the start. Without start enable, the motor cannot be started.
•
Switch S2 starts the motor in forward direcon of rotaon.
•
Switch S3 starts the motor in backward direcon of rotaon.
•
The motor is stopped by cancelling the run commands (switches S2 and S3 open) or by
cancelling the start enable (switch S1 open).
