Number ContentsMessage
078 NUMBER NOT FOUND A program number or a sequence number which was specified by
address 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 back-
ground processing. Correct the program, or discontinue the back-
ground 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 mea-
surement 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 spe-
cified or the command is incremental. Modify the program.
085 COMMUNICATION ERROR When entering data in the memory by using Reader / Puncher inter-
face, 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 incorrect.
086 DR SIGNAL OFF When entering data in the memory by using Reader / Puncher inter-
face, 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
defective.
087 BUFFER OVERFLOW When entering data in the memory by using Reader / Puncher inter-
face, 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
position 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
automatic operation was interrupted, the coordinate system setting
operation 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
automatic operation was interrupted, the workpiece offset amount
changed.)
Perform the correct operation according to th 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 alarm 94 to 97 were reset, no auto-
matic operation was performed.) Perform automatic operation.
