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.

PC050 I/OLINK(CHx)
A communication error occurred in the I/O Link.
aa:bb-aa:bb
CHx is channel number.
or
aa and bb indicate internal error code.
PC050 IOLINK CHx
aabb- aabb:aabb
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.

PC060 FBUS
A bus error occurred in the PMC.
xxxxxxxx:yyyyyyyy
aa, xxxxxxxx, and yyyyyyyy indicate internal error code.
PC061 FL-R

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.

PC097 PARITY ERR
A parity error occurred in the PMC system.
(LADDER)
PC098 PARITY ERR (DRAM)
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 occurrences, etc.) to FANUC.

ALARM LIST
When a serial spindle alarm occurs, the following number is displayed on
(SERIAL SPINDLE)
the CNC. n is a number corresponding to the spindle on which an alarm
occurs.
(n = 1: First spindle; n = 2: Second spindle; etc.)
NOTE*1
Note that the meanings of the SPM indications differ
depending on which LED, the red or yellow LED, is on.
When the red LED is on, the SPM indicates a 2-digit alarm
number. When the yellow LED is on, the SPM indicates an
error number that designates a sequence problem (for
example, when a rotation command is entered with the
emergency stop state not released).

Note that the meanings of the SPM indications differ
depending on which LED, the red or yellow LED, is on.
When the yellow LED is on, an error code is indicated with
a 2-digit number. The error code is not displayed on the
CNC screen.
When the red LED is on, the SPM indicates the number of
