1 Check the parameter settings with the parameter list.
1825 Individual–axis servo loop gain (Standard value : 3000)
2 It is likely that the servo system is abnormal. Make a check by
referring to the descriptions of servo alarms SV023, SV008, and
SV009.
b. The override value for the manual feedrate is 0%.
Check the following signals, using the PMC diagnostic function
(PMCDGN).

If the override value is 0%, all bits at the addresses shown above
become 111.....111 or 000.....000.
c. The interlock/start lock signal is active.
Check the following signal, using the PMC diagnostic function
(PMCDGN).
1 The interlock signal (*IT) is active.
#7
G000
#6 #5 #4 #3 #2 #1 #0
*IT
The interlock signal with *IT = 0 is active.
2 The individual–axis interlock signal (*ITn), servo–off signal
(*SVFn), or control signal detach signal (DTCHn) is on.

*SVF1
#5 #4
*IT1
#3 #2 #1 #0
(First axis)
The address of the nth axis is calculated as follows:
64 + (n – 1)*4
The interlock signal with *ITn, *SVFn = 0, and DTCHn = 1 is
active.
3 The automatic operation all–axis interlock (*AIT) or the block
start interlock signal (*BSL) is active.
#7
G001
#6 #5 #4 #3 #2 #1
*BSL
#0
*AIT
The interlock signal with *AIT and *BSL = 0 is active.
4 The cutting block start interlock signal (*CSL) is active.
#7
G000
#6 #5 #4 #3 #2 #1
*CSL
#0
The interlock signal with *CSL = 0 is active.
