Number ContentsMessage
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.
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 dueto systemover-
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
(Hobbing 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.
231 ILLEGAL FORMAT IN G10 OR L50 Any of the following errors occurred in the specified format at the pro-
grammable--parameter input.
1 Address N or R was not entered.
2 A number not specified for a parameter was entered.
3 The axis number was too large.
4 An axis number was not specified in the axis --type parameter.
5 An axis number was specified in the parameter which is not an axis
type. Correct the program.
6 In the locked state set by the password function, an attempt was
made to set bit 4 (NE9) of parameter No. 3204 to 0 or change the con-
tents of parameter No. 3210.
7 An attempt was made to change a program encryption parameter
(parameter No. 3220 to 3223).
232 TOO MANY HELICAL AXIS
COMMANDS (M series)
Three or more axes (in the normal direction control mode two or more
axes) were specified as helical axes in the helical interpolation mode.
233 DEVICE BUSY When an attempt was made to use a unit such as thatconnected via the
RS--232--C interface, other users were using it.
239 BP/S ALARM While punching was being performed with the function for controlling ex-
ternal I/O units ,background editing was performed.
240 BP/S ALARM Background editing was performed during MDI operation.
241 ILLEGAL FORMAT IN G02.2/G03.2
(M series)
The end point, I, J, K, or R is missing from a command for involute inter-
polation.
242 ILLEGAL COMMAND IN
G02.2/G03.2
(M series)
An invalid value has been specified for involute interpolation.
S The start or end point is within the basic circle.
S I, J, K, or R is set to 0.
S The number of rotations between the start of the involute curve and
the start or end point exceeds 100.
243 OVER TOLERANCE OF END POINT
(M series)
The end point is not on the involute curve which includes the start point
and thus falls outside the range specified with parameter No. 5610.
244 P/S ALARM
(T series)
In the skip function activated by the torque limitsignal, the number of ac-
cumulated erroneous pulses exceed 32767 before the signal was input.
Therefore, the pulses cannot be corrected with one distribution.
Change the conditions, such as feed rates along axes and torque limit,
and try again.
