10.2.2 Guard Open Request Signal (ORQ)
NOTES
Create a Ladder program of conditions for making a guard open
request and then input the program to the PMC side [G191#3].
When the guard open request signal (ORQ) is input and when CNC
safety has been confirmed, the guard unlock signal (*LGD) is output.
If the CNC is not safe, ORQ input will not result in output of *LGD.
If the input of ORQ is canceled while the guard is open, the CNC
enters a safely stopped status (state in which the guard is open
although the guard open request signal is not input). Close the guard
(SGD is set to 1), then cancel this signal.
