Number Message Description
407 SERVO ALARM:
EXCESS ERROR
The following error has occurred during
an operation under simplified synchro-
nization control:
The difference in machine coordinate
value between axes in synchronization
has exceeded a value specified in pa-
rameter No. 8314.
410 SERVO ALARM:
n AXIS EXCESS ERR
The most likely causes are:
1 For the n axis, the positional devi-
ation observed when the axis is
stopped has exceeded the value
set in parameter No. 1829.
2 In simple synchronous control, the
compensation used during syn-
chronous compensation has ex-
ceeded the value set in parameter
No. 8315 or 8325. This alarm oc-
curs only for the slave axis.
420 SERVO ALARM:
n AXIS SYNC TORQUE
A torque command issued for the mas-
ter or slave axis is greater than the val-
ue specified in parameter No. 2031.
This alarm condition occurs only for the
master axis.
Number Message Description
540 SYNCHRO ERROR The data represents the difference in
position error between the master and
slave axes during synchronous control.
(One master/slave axis pair under syn-
chronous control)
541 SYNCHRO ERROR The positional difference between the
master and slave axes under synchro-
nous control is displayed. (Two master/
slave axis pair under synchronous con-
trol)
