Number ContentsMessage
ILLEGAL AXIS COMMAND IN G37
(M series)
In automatic tool length measurement, an invalid axis was specified or
the command is incremental. Modify the program.
083
ILLEGAL AXIS COMMAND IN G37
(T series)
In automatic tool compensation (G36, G37), an invalid axis was speci-
fied or the command is incremental. Modify the program.
085 COMMUNICATION ERROR When entering data in the memory by using Reader / Puncher interface,
an overrun, parity or framing error was generated. The number of bits
of input data or setting of baud rate or specification No. of I/O unit is in-
correct.
086 DR SIGNAL OFF When entering data in the memory by using Reader / Puncher interface,
the ready signal (DR) of reader / puncher was turned off.
Power supply of I/O unit is off or cable is not connected or a P.C.B. is de-
fective.
087 BUFFER OVERFLOW When entering data in the memory by using Reader / Puncher interface,
though the read terminate command is specified, input is not interrupted
after 10 characters read. I/O unit or P.C.B. is defective.
090 REFERENCE RETURN
INCOMPLETE
The reference position return cannot be performed normally because
the reference position return start point is too close to the reference posi-
tion or the speed is too slow. Separate the start point far enough from
the reference position, or specify a sufficiently fast speed for reference
position return. Check the program contents.
091 REFERENCE RETURN
INCOMPLETE
Manual reference position return cannot be performed when automatic
operation is halted.
092 AXES NOT ON THE REFERENCE
POINT
The commanded axis by G27 (Reference position return check) did not
return to the reference position.
094 P TYPE NOT ALLOWED
(COORD CHG)
P type cannot be specified when the program is restarted. (After the au-
tomatic operation was interrupted, the coordinate system setting opera-
tion was performed.)
Perform the correct operation according to th operator’s manual.
095 P TYPE NOT ALLOWED
(EXT OFS CHG)
P type cannot be specified when the program is restarted. (After the
automatic operation was interrupted, the external workpiece offset
amount changed.)
Perform the correct operation according to th operator’s manual.
096 P TYPE NOT ALLOWED
(WRK OFS CHG)
P type cannot be specified when the program is restarted. (After the au-
tomatic operation was interrupted, the workpiece offset amount
changed.)
Perform the correct operation according to the operator’s manual.
097 P TYPE NOT ALLOWED
(AUTO EXEC)
P type cannot be directed when the program is restarted. (After power
ON, after emergency stop or P / S 94 to 97 reset, no automatic operation
is performed.) Perform automatic operation.
098 G28 FOUND IN SEQUENCE
RETURN
A command of the program restart was specified without the reference
position return operation after power ON or emergency stop, and G28
was found during search.
Perform the reference position return.
099 MDI EXEC NOT ALLOWED
AFT. SEARCH
After completion of search in program restart, a move command is given
with MDI. Move axis before a move command or don’t interrupt MDI op-
eration.
100 PARAMETER WRITE ENABLE On the PARAMETER(SETTING) screen, PWE(parameter writing en-
abled) is set to 1. Set it to 0, then reset the system.
101 PLEASE CLEAR MEMORY The power turned off while rewriting the memory by program edit opera-
tion. If this alarm has occurred, press <RESET> while pressing
<PROG>, and only the program being edited will be deleted.
Register the deleted program.
109 FORMAT ERROR IN G08
(M series)
A value other than 0 or 1 was specified after P in the G08 code, or no
value was specified.
110 DATA OVERFLOW The absolute value of fixed decimal point display data exceeds the al-
lowable range. Modify the program.
