5242 ILLEGAL AXIS NUMBER
(M series)
The axis number of the synchronous master axis or slave axis is incor-
rect. (This alarm is issued when flexible synchronization is turned on.)
Alternatively, the axis number of the slave axis is smaller than that of the
master axis.
5243 DATA OUT OF RANGE
(M series)
The gear ratio is not set correctly. (This alarm is issued when flexible
synchronization is turned on.)
5244 TOO MANY DI ON
(M series)
Even when an M code was encountered in automatic operation mode,
the flexible synchronization mode signal was not driven on or off.
Check the ladder and M codes.
5245 OTHER AXIS ARE COMMANDED
(M series)
One of the following command conditions was present during flexible
synchronization or when flexible synchronization was turned on:
1. The synchronous master axis or slave axis is the EGB axis.
2. The synchronous master axis or slave axis is the chopping axis.

rameter.
5252 ILLEGAL P COMMAND IN G54.2
(M series)
The P value specifying the offset number of a fixture offset is too large.
Correct the program.
5257 G41/G42 NOT ALLOWED IN MDI
MODE
(M series)
G41/G42 (cutter compensation C: M series) was specified in MDI
mode. (Depending on the setting of bit 4 of parameter No. 5008)
G41/G42 NOT ALLOWED IN MDI
MODE
(T series)
G41/G42 (tool–nose radius compensation: T series) was specified in
MDI mode. (Depending on the setting of bit 4 of parameter No. 5008)
5300 SET ALL OFFSET DATAS AGAIN After the inch/metric automatic conversion function (OIM: Bit 0 of pa-
rameter No. 5006) for tool offset data is enabled or disabled, all the tool
offset data must be reset. This message reminds the operator to reset
the data.
If this alarm is issued, reset all the tool offset data. Operating the ma-
chine without resetting the data will result in a malfunction.
5302 ILLEGAL COMMAND IN G68 MODE A command to set the coordinate system is specified in the coordinate
system rotation mode.
