APPENDIXA. ALARM LIST
B–63505EN/02
320
*When ER00 to ER26 occur, sequence program is not available.
Message Contents and solution
WN02 OPERATE PANEL
ADDRESS ERROR
The address setting data of the operator’s panel for FS to 0 is illegal.
(solution) Please correct the address setting data.
WN03 ABORT NC to WINDOW/
EXIN
LADDER was stopped while CNC and PMC were communicating.
The functional instruction WINDR, WINDW, EXIN, DISPB, and etc. may not work nor-
mally.
(solution) When restarting the system, this alarm will be released. Execute the
sequence program(Press RUN key) after confirming whether there is a
problem in LADDER or not.
WN05 PMC TYPE NO
CONVERSION
A ladder program for the PMC to RA3/RA5 was transferred to the PMC to RB5.
(solution) Correct the ladder type.
WN07 LADDER SP ERROR
(STACK)
When functional instruction CALL(SUB65) or CALLU(SUB66) was executed, the stack
of the LADDER overflowed.
(solution) Please reduce the nesting of the subprogram to 8 or less.
(2) Alarm messages (For EDIT)
Message Contents and solution
ADDRESS BIT NOTHING The address of the relay/coil is not set.
FUNCTION NOT FOUND There is no functional instruction of the input number.
COM FUNCTION MISSING The funcitonal instruction COM (SUB29) is not correctly dealt with.
Correspondence of COM and COME (SUB29) is incorrect.
Or, the number of coil controlled by COM is specified by the model which the number
cannot be specified.
EDIT BUFFER OVER There in no empty area of the buffer for the editing.
(solution) Please reduce NET under editing.
END FUNCTION MISSING Functional instruction END1 and END2 do not exist. Or, there are error net in END1 and
END2.
Or, order of END1 and END2 is not correct.
ERROR NET FOUND There is an error net.
ILLEGAL FUNCTION NO. The wrong number of the functional instruction is searched.
FUNCTION LINE ILLEGAL The functional instruction is not correctly connected.
HORIZONTAL LINE ILLEGAL The horizontal line of the net is not connected.
ILLEGAL NETS CLEARED Because the power had been turn off while editing LADDER, some net under editing
was cleared.
ILLEGAL OPERATION Operation is not correct.
The value is not specified and only INPUT key was pushed.
The address data is not correctly inputted.
Because the space to display the instruction on screen is not enough, the functional
instruction cannot be made.
SYMBOL UNDEFINED The symbol which was inputted is not defined.
INPUT INVALID There is an incorrect input data.
Non–numerical value was inputted with COPY, INSLIN,C–UP,C–DOWN etc.
The input address was specified for write coil.
An illegal character was specified for the data table.
NET TOO LARGE The input net is larger than the editing buffer.
(solution) Please reduce the net under editing.
JUMP FUNCTION MISSING The functional instruction JMP(SUB10) is not correctly dealt with.
Correspondence of JMP and JMPE(SUB30) is incorrect.
The number of coil to jump is specified by the model which the number of coil cannot
specified. (It is possible to specify the coil number only on PMC–RB/RC.)
LADDER BROKEN LADDER is broken.
LADDER ILLEGAL There is an incorrect LADDER.
IMPOSSIBLE WRITE You try to edit sequence program on the ROM.
OBJECT BUFFER OVER The sequence program area was filled.
(solution) Please reduce the LADDER.
