There are a plural number of interlock functions. Parameters are set by
machine tool builders for which interlock function is used.
Therefore, confirm the following parameters at first:
#7
3003
#6 #5 #4 #3
DIT
#2
ITX
#1
HITL
#0
ITL
#0 ITL=0 shows interlock signal *IT is effective. To 1
#1 HITL = 1 shows interlock signal *RILK is effective. To 2
#2 ITX=0 shows interlock signal *ITn is effective. To 3
#3 DIT=0 shows interlock signal "MITn is effective. To 4
Check state of effective interlock signals using the diagnostic function
(PMCDGN) of the PMC.
1 Interlock signal (*IT) is input

"MITn=1 shows interlock signal per axis and direction is input.
5 Controlled axis detach function is running. A detached axis is
specified for travelling.
*This function is valid when parameter No.1005#7 (RMB)=1. For
whether this function is running or not, confirm the following signal
using PMCs diagnostic function (PMCDGN). Check the axis
concerned.
