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
DAU
#3
DIT
#2
ITX
#1 #0
ITL
#0 (ITL) 0 : Interlock signal(*IT) is valid.
#2 (ITX) 0 : Interlock signal (*ITn) is valid.
#3 (DIT) 0 : Interlock signal ("MITn) is valid.
#4 (DAU) 1 : Interlock signal ("MITn) is valid in both manual operation and
automatic operation.
Confirm which interlock signal is activated by the PMC’s diagnostic
function (PMCDGN) .
1) Interlock signal (*IT) is input

"MITn=1 shows interlock signal per axis and direction is input.
* For the T series, "MITn is valid only for manual operation.
4) Controlled axis detach function is running. A detached axis is
specified for travelling.
*This function is valid when CNC parameter No.1005#7=1. For
whether this function is running or not, confirm the following signal
using PMC’s diagnostic function (PMCDGN). Check the axis
concerned.
