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
#0 (ITL) 0 : Interlock signal(*IT) is valid. To 1
#2 (ITX) 0 : Interlock signal (*ITn) is valid. To 3
Confirm which interlock signal is activated by the PMC’s diagnostic
function (PMCDGN) .
1 Interlock signal (*IT) is input
#7 #6 #5 #4 #3 #2 #1 #0
G0008 *IT
#0 (*IT) : When this bit is 0, interlock signal is input.
2 Interlock signal per each axis (*ITn) is input
#7 #6 #5 #4 #3 #2 #1 #0
G0130 *IT2 *IT1
*ITn When the bit is 0, the corresponding axis’s interlock signal is
input.
Actual spindle speed does not arrive at a speed specified in a program.
Confirm the signal state using the PMC’s diagnostic function
(PMCDGN).
#7 #6 #5 #4 #3 #2 #1 #0
G0029 SAR
#4(SAR) : When this signal is 0, spindle speed does not arrive at the
specified speed.
This function is valid when PRM SAR (3708#0)=1.
Normally manual feedrate override function is used for jog feed.
But when DRN(dry run) signal turns on during an auomatic
operation,override values set with these signals become valid to the
following speed set by a parameter.
#7 #6 #5 #4 #3 #2 #1 #0
G0046 DRN
#7(DRN) : Dry run signal is input with this signal being 1.
1410 Dry run rate for each axis [mm/min]
The rate when the following override value is 100%.
#7 #6 #5 #4 #3 #2 #1 #0
G0010 *JV7 *JV6 *JV5 *JV4 +JV3 *JV2 *JV1 *JV0
G0011 *JV15 *JV14 *JV13 *JV12 +JV11 *JV10 *JV9 *JV8
When override value is 0%, all bits of the above address is
[1111 1111] or [0000 0000].. . . . . .
