Contents and solutionMessage
5 PC070 SUB65 CALL (STACK) A stack error occurred during execution of ladder function instruction
CALL/CALLU.
Solution)
Check the correspondence between the CALL/CALLU instruction and SPE
instruction. If the error cannot be located, report the conditions under which the
error occurred and the ladder program to FANUC.
6 PC080 SYS EMG
xxxxxxxx:yyyyyyyy
PC081 FL EMG
xxxxxxxx:yyyyyyyy
A system alarm was caused by another software.
Solution)
Report the conditions under which the error occurred (system configuration, op-
eration, time and frequency of error occurrences, etc.), the indicated internal er-
ror code, and the LED status on each board to FANUC.
7 PC097 PARITY ERR
(LADDER)
PC098 PARITY ERR (DRAM)
A parity error occurred in the PMC system.
If this error occurred, the motherboard may be faulty.
Solution)
Replace the motherboard, then check whether the error recurs. If the error still
occurs even after the replacement of the motherboard, report the conditions un-
der which the error occurred (system configuration, operation, time and frequen-
cy of error oc currences, etc.) to FANUC.

Message Contents and solution
1 PC1nn CPU INTERRT
xxxxyyyyyy
STATUS LED lL
CPU error (abnormal interrupt)
nn : Exception code
Exception code of the i80486. For details, refer to the relevant
manual that describes the CPU.
00 Division error. For example, the divisor in a division instruction is 0.
12 Stack exception caused by, for example, stack segment limit viola
tion
13 General protection exception generated when, for example, a seg
ment limit is exceeded
xxxx : Segment selector where the system error occurred
A value 0103 to 02FB indicates the C execution area.
yyyyyy : Offset address at which the system error occurred
(Solution)
If a C program is not used, or if the cause of the error cannot be determined
even by checking the C program, contact FANUC.
