5242 ILLEGAL AXIS NUMBER
(M series)
The axis number of the synchronous mas-
ter axis or slave axis is incorrect. (This
alarm is issued when flexible synchroniza-
tion 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 synchroniza-
tion is turned on.)
5244 TOO MANY DI ON
(M series)
Even when an M code was encountered in
automatic operation mode, the flexible syn-
chronization 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 synchroniza-
tion 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.
3. In reference position return mode
5251 ILLEGAL PARAMETER IN
G54.2
(M series)
A fixture offset parameter (PRM7580–7588) is
illegal. Correct the parameter.
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 pro-
gram.
5257 G41/G42 NOT ALLOWED IN
MDI MODE
(M series)
G41/G42 (cutter compensation C: M se-
ries) was specified in MDI mode. (Depend-
ing on the setting of PRM5008#4)
G41/G42 NOT ALLOWED IN
MDI MODE
(T series)
G41/G42 (tool–nose radius compensation:
T series) was specified in MDI mode. (De-
pending on the setting of PRM5008 #4)
5300 SET ALL OFFSET DATAS
AGAIN
After the inch/metric automatic conversion
function (PRM5006#0 (OIM)) for tool offset
data is enabled or disabled, all the tool off-
set data must be reset. This message re-
minds the operator to reset the data. If this
alarm is issued, reset all the tool offset
data. Operating the machine without reset-
ting the data will result in a malfunction.
