Number ContentsMessage
073 PROGRAM NUMBER ALREADY IN
USE
The commanded program number has already been used.
Change the program number or delete unnecessary programs and
execute program registration again.
074 ILLEGAL PROGRAM NUMBER The program number is other than 1 to 9999.
Modify the program number.
075 PROTECT An attempt was made to register a program whose number was pro-
tected.
076 ADDRESS P NOT DEFINED Address P (program number) was not commanded in the block which
includes an M98, G65, or G66 command. Modify the program.
077 SUB PROGRAM NESTING ERROR The subprogram was called in five folds. Modify the program.
078 NUMBER NOT FOUND A program number or a sequence number which was specified by ad-
dress P in the block which includes an M98, M99, M65 or G66 was not
found. The sequence number specified by a GOTO statement was not
found. Otherwise, a called program is being edited in background pro-
cessing. Correct the program, or discontinue the background editing.
079 PROGRAM VERIFY ERROR In memory or program collation,a program in memory does not agree
with that read from an external I/O device. Check both the programs in
memory and those from the external device.
080 G37 ARRIVAL SIGNAL NOT
ASSERTED
In the automatic tool compensation function (G36, G37), the measure-
ment position reach signal (XAE or ZAE) is not turned on within an area
specified in parameter 6254 (value ε).
This is due to a setting or operator error.
081 OFFSET NUMBER NOT FOUND IN
G37
Automatic tool compensation (G36, G37) was specified without a T
code. (Automatic tool compensation function) Modify the program.
082 T–CODE NOT ALLOWED IN G37 T code and automatic tool compensation (G36, G37) were specified in
the same block. (Automatic tool compensation function)
Modify the program.
083 ILLEGAL AXIS COMMAND IN G37 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
In the automatic operation halt state, manual reference position return
cannot be performed.
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.
