Set a safe machine position for each axis.
The CNC and monitor always check the machine position on each
linear axis in the dual check safety function.
In safety signal mode B (state in which a guard open request is input,
and the guard is closed), if there is at least one linear axis whose
machine position is not in the safe machine position, the guard unlock
signal (*LGD) is set to 0 to disable guard unlocking. The state in
which the machine positions of all linear axes are within the safe
machine positions is one condition for setting the guard unlock signal
(*LGD) to 1 (to enable guard unlocking). If the machine position on a
linear axis exceeds the safe machine position in safety signal mode C
(state in which a guard open request is input and the guard is open), a
servo alarm No.477 or No.495 is issued.
Up to four safe machine positions can be set. Which safe machine
positions to choose depends on the safety speed/safety position
selection signal (safety input signal).
Safe machine position 1 assumes the value of parameter No. 1943 (No.
1944) if parameter No. 1943 (No. 1944) is not set to 0. Safe machine
position 1 assumes the value of parameter No. 13831 (13832) if
parameter No. 1943 (No. 1944) is set to 0.
