(d) Interlock signal is input
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 #6 #5 #4 #3 #2 #1 #0
3003 ITX ITL
ITL 0: Interlock signal(*IT) is valid.
ITX 0: Interlock signal (*ITn) is valid.
Confirm which interlock signal is activated by the PMC's
signal status screen.
(i) Interlock signals (*IT, *CSL, and *BSL) are input.
#7 #6 #5 #4 #3 #2 #1 #0
G0008 *IT
*IT=0, *CSL=0, and *BSL=0 show that interlock
signal is input.
(ii) Interlock signal per each axis (*ITn) is input
#7 #6 #5 #4 #3 #2 #1 #0
G0130 *IT8 *IT7 *IT6 *IT5 *IT4 *IT3 *IT2 *IT1
When the bit is 0, the corresponding axis's interlock
signal is input.
(iii) Controlled axis detach function is running. A detached
axis is specified for travelling.
