Number ContentsMessage
231 ILLEGAL FORMAT IN G10 OR L50 Any of the following errors occurred in the specified format at the
programmable–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.
6) An attempt was made to reset bit 4 of parameter 3202 (NE9) or
change parameter 3210 (PSSWD) when they are protected by a
password. Correct the program.
232 TOO MANY HELICAL AXIS COM-
MANDS
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 that connected 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
external 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 The end point, I , J , K , or R was not specified for involute
interpolation.
242 ILLEGAL COMMAND IN
G02.2/G03.2
An erroneous value was specified for involute interpolation.
The start or end point was specified within the base circle.
The value 0 was specified for I , J, K , or R,.
The start or end point exceeds 100 revolutions from the involute
curve start point.
243 OVER TOLERNCE OF END POINT The end point was not positioned on the involute curve which started
at the start point, and the end point was out of the range specified by
parameter No.5610.
246 During read of an encrypted program, an attempt was made to store the
program with a number exceeding the protection range.
(See parameter Nos. 3222 and 223.)
247 When an encrypted program is output, EIA is set for the punch code.
Specify ISO.
250 Z AXIS WRONG COMMAND (ATC) In a system using the DRILL–MATE with an ATC, movement alogn
the Z–axis was specified in a block in which a command for changing
tools (M06 T_)was specified.
251 ATC ERROR An error occurs in the DRILL–MATE in the following cases :
When unusable T code is specified in M06 T_
When the M06 code is specified when the Z coordinate is positive
in the machine coordinate system.
When parameter No. 7810,which specifies the current tool number,
is 0.
When the M06 code is specified in the canned–cycle mode.
When the M06 code is specified in a block in which a reference posi-
tion return code, G27,G28, G29, or G30 is specified.
When the M06 code is specified in the tool compensation mode
(G41 to G44).
When the M06 code is specified without any reference position re-
turn after the power is turned on or after the emergency stop is re-
leased.
When the machine lock signal or the signal for ignoring the Z–axis
is turned on while the tool is being changed.
When a “prying” condition is detected while the tool is changed.
Refer to diagnosis parameter No. 530 for identifying the situations
above.
