There are a plural interlock signals. Check at first which interlock signal
is used by the machine tool builder at the parameters shown below.

#6 #5 #4 #3
DIT
#2
ITX
#1 #0
ITL
#0 ITL=0 shows interlock signal *IT is effective. To 1)
#2 ITX=0 shows interlock signal *ITn is effective. To 2)
#3 DIT=0 shows interlock signal ± MITn is effective. To 3)
Check state of effective interlock signals using the diagnostic function
(PMCDGN) of the PMC.
1) Interlock signal (*IT) is input.

*IT=0 shows that interlock signal is input.
2) Axis interlock signal (*ITn) is input.

In this case, RESET is also displayed on the status display. Check it using
the procedure of 1 above.
