Number ContentsMessage
213 ILLEGAL COMMAND IN
SYNCHRO–MODE
(M series)
Movement is commanded for the axis to be synchronously controlled.
Any of the following alarms occurred in the operation with the simple
synchronization control.
1) The program issued the move command to the slave axis.
2) The program issued the manual continuous feed/manual handle
feed/incremental feed command to the slave axis.
3) The program issued the automatic reference position return com-
mand without specifying the manual reference position return after
the power was turned on.
4) The difference between the position error amount of the master and
slave axes exceeded the value specified in parameter NO.8313.
ILLEGAL COMMAND IN
SYNCHRO–MODE (T series)
A move command has been specified for an axis subject to synchro-
nous control.
214 ILLEGAL COMMAND IN
SYNCHRO–MODE
Coordinate system is set or tool compensation of the shift type is
executed in the synchronous control. Correct the program.
217 DUPLICATE G51.2 (COMMANDS)
(T series)
G51.2/G251 is further commanded in the G51.2/G251 mode. Modify
the program.
218 NOT FOUND P/Q COMMAND IN
G251 (T series)
P or Q is not commanded in the G251 block, or the command value is
out of the range. Modify the program.
219 COMMAND G250/G251
INDEPENDENTLY (T series)
G251 and G250 are not independent blocks.
220 ILLEGAL COMMAND IN
SYNCHR–MODE (T series)
In the synchronous operation, movement is commanded by the NC pro-
gram or PMC axis control interface for the synchronous axis.
221 ILLEGAL COMMAND IN
SYNCHR–MODE (T series)
Polygon machining synchronous operation and axis control or balance
cutting are executed at a time. Modify the program.
222 DNC OP. NOT ALLOWED IN
BG.–EDIT (M series)
Input and output are executed at a time in the background edition.
Execute a correct operation.
224 RETURN TO REFERENCE POINT
(M series)
Reference position return has not been performed before the automatic
operation starts. Perform reference position return only when bit 0 of pa-
rameter 1005 is 0.
TURN TO REFERENCE POINT
(T series)
Reference position return is necessary before cycle start.
225 SYNCHRONOUS/MIXED CONTROL
ERROR
(T series (At two–path))
This alarm is generated in the following circumstances. (Searched for
during synchronous and mixed control command.
1 When there is a mistake in axis number parameter (No. 1023) set-
ting.
2 When there is a mistake in control commanded.
During hobbing synchronization, a command to bring the C–axis under
synchronous, composite, or superimposed control is made.
Modify the program or the parameter.
226 ILLEGAL COMMAND IN SYNCHRO–
MODE (T series (At two–path))
A travel command has been sent to the axis being synchronized in syn-
chronous mode. Modify the program or the parameter.
229 CAN NOT KEEP SYNCHRO–STATE
(T series)
This alarm is generated in the following circumstances.
1 When the synchro/mixed state could not be kept due to system over-
load.
2 The above condition occurred in CMC devices (hardware) and syn-
chro–state could not be kept.
(This alarm is not generated in normal use conditions.)
230 R CODE NOT FOUND
(Grinding machine) (M series)
The infeed quantity R has not been instructed for the G161 block. Or
the R command value is negative. Correct the program.
