(2) System alarm messages (PMC–SB7)
Message Contents and solution
1 PC004 CPU ERR
xxxxxxxx:yyyyyyyy
PC006 CPU ERR
xxxxxxxx:yyyyyyyy
PC009 CPU ERR
xxxxxxxx:yyyyyyyy
PC010 CPU ERR
xxxxxxxx:yyyyyyyy
A CPU error occurred in the PMC.
xxxxxxxx and yyyyyyyy indicate internal error code.
If this error occurs, the motherboard may be faulty.
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 occurrences, etc.) to FANUC.
2 PC030 RAM PARITY aa:bb A RAM parity error occurred in the PMC.
aa and bb indicate internal error code.
If this error occurs, 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 occurrences, etc.) and the indicated internal error code to FANUC.
3 PC050 NMI SLC aa:bb A communication error occurred in the I/O Link.
aa and bb indicate internal error code.
If this error occurs, the possible causes are as follows:
(1) Although the base expansion is assigned when the I/O Unit A is used, the
base is not connected.
(2) A cable is not connected securely.
(3) Cabling is faulty.
(4) I/O equipment (I/O unit, Power Mate, etc.) is faulty.
(5) The power to the master or slave unit of the I/O Link is disconnected.
(6) A DO–pin short–circuit occurred in an I/O device.
(7) The motherboard is faulty.
Solution)
(1) Check whether the I/O assignment data and the actual I/O equipment con-
nection match.
(2) Check whether the cables are connected correctly.
(3) According to “FANUC I/O Unit–MODEL A Connection and Maintenance
Manual” (B–61813E) or “FANUC I/O Unit–MODEL B Connection manual”
(B–62163E), check for an error in the cable specifications.
(4) Replace the I/O unit interface module, cable, or motherboard. Then, check
whether the error still occurs.
4 PC060 FBUS
xxxxxxxx:yyyyyyyy
PC061 FL–R
xxxxxxxx:yyyyyyyy
PC062 FL–W
aa: xxxxxxxx:yyyyyyyy
A bus error occurred in the PMC.
aa, xxxxxxxx, and yyyyyyyy indicate internal error code.
If this error occurs, the hardware may be faulty.
Solution)
Report the conditions under which the error occurred (system configuration, op-
eration, time and frequency of error occurrences, tc.), the indicated internal error
code, and the LED status on each board to FANUC.
