A. ALARM LIST

Number ContentsMessage
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.
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.
110 DATA OVERFLOW The absolute value of fixed decimal point display data exceeds the al-
lowable range. Modify the program.
111 CALCULATED DATA OVERFLOW The result of calculation turns out to be invalid, an alarm No.111 is is-
sued.

112 DIVIDED BY ZERO Division by zero was specified. (including tan 90°)
Modify the program.
113 IMPROPER COMMAND A function which cannot be used in custom macro is commanded.
Modify the program.
114 FORMAT ERROR IN MACRO There is an error in other formats than <Formula>.
Modify the program.
115 ILLEGAL VARIABLE NUMBER A value not defined as a variable number is designated in the custom
macro or in high–speed cycle machining.
116 WRITE PROTECTED VARIABLE The left side of substitution statement is a variable whose substitution
is inhibited. Modify the program.
118 PARENTHESIS NESTING ERROR The nesting of bracket exceeds the upper limit (quintuple).
Modify the program.
119 ILLEGAL ARGUMENT The SQRT argument is negative. Or BCD argument is negative, and
other values than 0 to 9 are present on each line of BIN argument.
Modify the program.
122 FOUR FOLD MACRO MODAL–CALL The macro modal call is specified four fold.
Modify the program.
123 CAN NOT USE MACRO COMMAND
IN DNC
Macro control command is used during DNC operation.
Modify the program.
124 MISSING END STATEMENT DO – END does not correspond to 1 : 1. Modify the program.
125 FORMAT ERROR IN MACRO <Formula> format is erroneous. Modify the program.
126 ILLEGAL LOOP NUMBER In DOn, 1x n x3 is not established. Modify the program.
127 NC, MACRO STATEMENT IN SAME
BLOCK
NC and custom macro commands coexist.
Modify the program.
