10.9 DOUBLE-ACTING PISTON CONTROL MONITORED BY TWO SENSORS (AN EXAMPLE)
Assumptions:
Piston with advance / return 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.
10.9.1Configurating Optional Socket 1 Outside Program Loop
M800 P1=1750 P2=1753 P3=1757:
1750 reverses input signal (enabled at 0).
1753 disables unused Input 2.
1757 selects an Alarm Class 3.
10.9.2Configurating Optional Socket 2 Outside Program Loop
M800 P1=1770 P2=1773 P3=1777:
1770 reverses input signal (enabled at 0).
1773 disables unused Input 2.
1777 selects an Alarm Class 3.
10.9.3Enable Sensor Check Inside Program Loop
M811 D811=16: enables piston advance control.
M812: disables piston advance control.
G04 X2: 2 s dwell
(acc. to the time necessary for piston to reach
the piston-forward sensor)
M815: enables check start by piston-forward input.
M813 D813=16: enables piston return control.
M814 disables piston return control.
reach the piston-backward sensor)
M825: enables check start by piston-backward input.
If Input 1 on Socket 1 is 0 and M815 enabled,
Alarm 1013: ALARM CLASS 3 OPTION SOCKET is displayed
and the operator must assume that the piston advance has not been properly
completed.
If Input 1 on Socket 2 is 0 and M825 enabled,
Alarm 1013: ALARM CLASS 3 OPTION SOCKET is displayed
and the operator must assume that the piston return has not been properly
completed.
