It shows that positioning is not yet completed. Check the contents of the
following diagnostic number. (It is 1 in the following condition)
DGN 0300
Position Error
>PARAM 1826
In–positio width
1 Check the parameters according to the parameter list
1825 Servo loop gain per axis (Normal : 3000)
2 Servo system may be abnormal. Refer to alarm 400, 410, and 411.
There are a plural interlock signals. Check at first which interlock signal
is used by the machine tool builder at the parameters shown below.
#7 #6 #5 #4 #3 #2 #1 #0
3003 DIT ITX HITL 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
#7 #6 #5 #4 #3 #2 #1 #0
G0008 *IT
*IT=0 shows that interlock signal is input.
2 High–speed interlock signal (*RILK) is input.
#7 #6 #5 #4 #3 #2 #1 #0
X0000 *RILK
or
X1000
*RILK = 0 shows interlock signal is input.
3 Axis interlock signal (*ITn) is input
#7 #6 #5 #4 #3 #2 #1 #0
G0130 *IT2 +IT1
*ITn=0 shows interlock signal is input.
4 Interlock signal per axis and direction (+/– MITn) is input
#7 #6 #5 #4 #3 #2 #1 #0
G0132 +MIT2 +MIT1
G0134 –MIT2 –MIT1
"MITn=1 shows interlock signal per axis and direction is input.
Check the signals using PMC’s diagnostic function (PMCDGN)
#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 the override is 0% all bits of the above address becomes
1111 1111 or 0000 0000.. . . . . . . . .
a. In–position check is
being done
b.Interlock signal is input
c. Jog feedrate override is
0%
