Number Message Description
213 ILLEGAL COMMAND IN
SYNCHRO–MODE
One of the following errors occurred
during synchronous operation (simple
synchronous control):
(1) The program contains a move command
for the slave axis.
(2) A command for jog feed, manual handle
feed, or incremental feed was issued for
the slave axis.
(3) After power on, the command for auto-
matic reference position return was spe-
cified before a manual reference
position return had been performed.
(4) The difference in position error between
the master and slave axes exceeded
the value set in parameter 8313.
Number Message Description
407 SERVO ALARM:
EXCESS ERROR
The difference in position error be-
tween the master and slave axes ex-
ceeded the value set with the parame-
ter 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. This alarm occurs only
for the slave axis.
Number Message Description
540 SYNCHRO ERROR The data represents the difference in
position error between the master and
slave axes during synchronous control.
