Cont. Signal name
Under SSM safe speed
A
(spindle)
[Function]
This signal indicates that the safe speed monitor has been enabled on the target spindle and that the spindle speed is
below the safe speed.

[Operation]
This signal turns ON when the "SSM request" (*SSMSRm) is turned OFF (when SSM is requested), the NC starts
execution of SSM, and then the speed of the spindle drops to the safe speed or lower. This signal remains OFF while the
spindle speed is exceeding the safe speed. This signal turns OFF when the "SSM request" (*SSMSRm) is turned ON
(when SSM is not requested).
[Related signals]
(1) SSM request (*SSMSRm)
(2) SSM is active (SSMSEm)
Cont.
A In safety external emergency stop (system common)
[Function]
This signal indicates that Safety external emergency stop is being executed.
[Operation]
This signal turns ON when the safety external emergency stop is enabled (when the emergency stop signal device No. is
set in the safety I/O assignment parameter), the emergency stop signal turns OFF (open status), the axis for which the
parameter "SF_Disable"/"SF_SDisable" is set to OFF enters STO status, and all the axes are set in Ready OFF status.
This signal turns OFF when the emergency stop signal turns ON (close status) and both the STO status of the axis for
which "SF_Disable"/"SF_SDisable" is set to OFF, and the Ready OFF status of all the axes are cancelled.
Cont.
A V number of smart safety observation error (system common) SFERR_VNO ZR1268
[Function]
This signal shows the category numbers of the smart safety observation error (V number).
[Operation]
When the smart safety observation error occurs, the number (V number) that shows the category of the error occurred is
output.
"0" is output when the smart safety observation error is not in occurrence state.
(Example) When the smart safety observation error "V04 0003 Safe IO disabled: connect err" occurs
V number of smart safety observation error (system common) (SFERR_VNO): 0004
[Related signals]
(1) E number of smart safety observation error (SFERR_ENO)
(2) Smart safety observation error occurring servo axis (SFERR_SVm)
(3) Smart safety observation error occurring spindle (SFERR_SPm)
