Guard open request signal
ORQ <G191#3>, ORQ2<G350#0>, ORQ3<G350#1>, ORQ4<G350#2>
[Classification] Input signal
[Function] This signal requests the CNC to unlock the guard with the dual check
safety function.
Guard open request signal (ORQ, ORQ2, ORQ3, ORQ4) is not input
via the FSSB.
In addition, the guard open request signal ORQ,ORQ2, ORQ3 and
ORQ4 corresponds to guard lock release signal *LGD, *LGD2,
*LGD3 and *LGD4 respectively.
[Operation] When the guard open request signal (ORQ) is 1, the CNC, monitor
and spindle software make a machine position check and safety speed
check. If the results of the checks assure safety, guard unlock signal
(*LGD) is set to 1 (to enable guard unlocking).
When guard open request signal (ORQ) is 0, the CNC and monitor set
guard unlock signal (*LGD) to 0 (to disable guard unlocking). (In
emergency stop state, however, the guard unlock signal (*LGD) is set
to 1.)
ORQ2 corresponds to *LGD2, ORQ3 corresponds to *LGD3, and
ORQ4 corresponds to *LGD4.
When the emergency stop signal *ESPG is input, all of *LGD to
*LGD4 are set to 1 (to guard unlock).
See Subsection 5.4.
For the setting of multiple doors, see the description of parameter No.
13800.
Guard state signal
SGD1 <G191#4>, SGD21<G332#4>, SGD31<G332#5>, SGD41<G332#6>,
SGD2<DI+001#4>, SGD22<DI+000#1>, SGD32<DI+000#2>, SGD42<DI+000#3>
[Classification] Input signal
[Function] This signal posts the guard open/closed state to the CNC and monitor
with the dual check safety function.
0: Guard open state
1: Guard closed state
[Operation] This input signal is used together with safety input signals such as
guard open request signal (ORQ to ORQ4) to determine a safety
signal mode that specifies the operation of the CNC, monitor, and
spindle software. For details, see Subsection 5.4.
Input this signal according to the guard state.
For the setting of multiple doors, see the description of parameter No.
13800.
NOTE
Use contacts conforming to IEC60947-5-1 for the
Guard state signal.
