HARDWARE

B-63525EN/02

(1) Hardware control LEDs

LED No.

Meaning

LED5

Lights when the CPU on the FANUC I/O Link-II board is run-

ning. When the LED is off, it means that the CPU has been

reset.

LED6

Lights when a DRAM parity error is detected.

It is likely that the hardware is defective.

(2) Soft control LEDs

Status LED

Meaning

(ST4 to 1)

JJJJ

Immediately after power is switched on.

JJjj

Communication board being initialized.

ljjj

DI/DO data is being transferred normally.

jjjJ

A RAM parity error has occurred.

It is likely that the hardware is defective.

jjJJ

An F-BUS error has occurred.

jjJj

An F-BUS system emergency condition has occurred. Alterna-

tively, a communication error (FCS error, command error, frame

length error, response time-out, etc.) has occurred.

ljJj

A communication error has occurred, resulting in error log being

stored. Communication with a slave station has restarted.

LED2 goes off when a log command (monitor function) is used.

It goes off also when the communication error log is erased

ljjj

using a clear command.

LED1 (CPU)

Lights to indicate the CPU for the slave function is running.

LED2 (COMM)

Lights when PROFIBUS communication starts. It remains to

be on after the PROFIBUS communication is suspended,

however.

LED3 (RUN)

Lights to indicate that PROFIBUS communication is being

performed normally.

LEDB (PALM)

Lights when a memory parity alarm occurs in the slave function

circuit.

HEALTH

Red/

This LED indicates the status of the daughter board. At

green

power-up, this LED glows in red. When the firmware is

loaded to the internal daughter board, the LED turns

green. Then, if something unusual occurs in the daughter

board, the LED turns red. If the LED does not turn green,

REPLACING THE

WARNING

MOTHERBOARD

Only those personnel who have received approved safety

and maintenance training may perform this replacement

work.

When opening the cabinet and replacing the board, be

careful not to touch the high-voltage circuits (marked and

fitted with an insulating cover). Touching the uncovered

high-voltage circuits presents an extremely dangerous

electric shock hazard.

CAUTION

Before starting replacement work, back up the contents

(such as parameters and programs) of the SRAM memory

of the CNC. Otherwise, the contents of the SRAM memory

may be lost during replacement work.

D Replacement procedure

1) Unscrew the four screws fastening the case, and remove the case. The

fan and battery cable do not have to be removed.

If the unit has a touch panel, the touch panel control PCB is on the left

when viewed from the back of the basic unit. Before removing the

case, remove the cables connected to this touch panel control PCB

(connectors CN1 and CD37).

2) Remove the cables from connectors CNM1A (PCMCIA interface

connector), CN8 (video signal interface connector) and CN2 (soft key

connector) on the motherboard. Then, unscrew the screws fastening

the motherboard. The connector CN3 (inverter connector) directly

connects the motherboard to the inverter PCB. Slide the motherboard

downward when removing the motherboard.

REPLACING FUSE

WARNING

ON CONTROL UNIT

Before replacing a blown fuse, locate and remove the cause

of the blown fuse.

For this reason, only those personnel who have received

approved safety and maintenance training may perform this

replacement work.

When opening the cabinet and replacing a fuse, be careful

not to touch the high-voltage circuits (marked

and fitted

with an insulating cover).

Touching the uncovered

high-voltage circuits presents an extremely dangerous

electric shock hazard.

A02B-0200-K102

WARNING

Using other than the recommended battery may result in the

battery exploding. Replace the battery only with the

specified battery (A02B-0200-K102).

CAUTION

Steps 1) to 3) should be completed within 30 minutes. Do

not leave the control unit without a battery for any longer

than the specified period. Otherwise, the contents of

memory may be lost.

If steps 1) to 3) may not be completed within 30 minutes,

save all contents of the SRAM memory to the memory card

beforehand. Thus, if the contents of the SRAM memory are

lost, the contents can be restored easily.

For the method of operation, refer to 4.9 or C.2.2.

When discarding a battery, observe the applicable ordinances or other

rules of your local government. Also, cover the terminals of the battery

with vinyl tape or the like to prevent a short-circuit.

D Method of connection

Power from the external batteries is supplied through the connector to

which the lithium battery is connected.

The lithium battery, provided as standard, can be replaced with external

batteries in the battery case (A02B-0236-C281) according to the battery

replacement procedure described above.

CAUTION

1

Install the battery case (A02B-0236-C281) in a location

where the batteries can be replaced even when the power

to the control unit is on.

2

The battery cable connector is attached to the control unit

by means of a simple lock system. To prevent the connector

from being disconnected due to the weight of the cable or

tension within the cable, fix the cable section within 50 cm

of the connector.
