10.8 SINGLE-ACTING PISTON CONTROL MONITORED BY TWO SENSORS (AN EXAMPLE)
Assumptions:
Piston with advance control.
Sensor for piston in forward position.
Sensor for piston in backward position.
The following requirements to be met:
Piston-forward sensing to be 1 before piston return.
If not, the program stops instantaneously by selecting an Alarm Class 3.
Piston-backward sensing to be 1 before machining is continued.
If not, the program stops instantaneously by selecting an Alarm Class 3.
