For the Series 0i-C, two types of basic unit are available.

The usable board differs depending on the basic unit.

PROFIBUS-DP Board

In this manual, boards are classified as “PROFIBUS-DP board A” and

“PROFIBUS-DP board B” for the sake of convenience.

REPLACING THE

WARNING

MAIN BOARD

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.

If the drawing number of the basic unit is A02B-0309-B50n,

D Replacement procedure

A02B-0311-B50n, or A02B-0311-B51n (where n is 0, 1, ..., 9)

2) Remove the cables from connectors CNM1A (PCMCIA interface

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

connector) on the main board. Then, unscrew the screws fastening the

main board. The connector CN3 (inverter connector) directly

connects the main board to the inverter PCB. Slide the main board

1) Unscrew the two screws fastening the case. (If a cable is connected

to the option card, you must first remove the cable before starting the

replacement work.)

2) Extract the case while releasing both of the claws at the top of the case

that are latched to the base plate.

You can extract the case with the back panel, fan, and battery

mounted.

2) Extract the case while

releasing the latches.

1) Unscrew the screws.

Then, unscrew the screws fastening the main board. Connector

CA115A directly connects the main board to the inverter PCB. Slide

the main board downward when removing the main board.

3) Unscrew the screws (at 3 places).

4) Replace the main board.

5) Slowly insert the cover while arranging the screw holes and latches

in the correct positions. When the cover is installed, the power supply

PCB on the cover and the main board are connected via their

connectors. You should insert the cover using caution to prevent

excessive strain on it while checking the connection between the

connectors.

6) Ensure that the cover latches are engaged securely, and then tighten

the cover screws. Push the fan and battery lightly to ensure that their

connections are established securely. (If you have removed the cable

from the option card, reconnect the cable.)

MOUNTING AND

WARNING

DEMOUNTING CARD

Only those personnel who have received approved safety

PCBS

and maintenance training may perform this replacement

work.

When opening the cabinet and replacing a card PCB, 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.

If the SRMA data check method (parity check or ECC check)

has been changed after the replacement, a parity or ECC

alarm may occur at power-on, possibly causing damage to

the SRAM data. Back up the SRAM data before starting

replacement, and restore the data after completing the

replacement.

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.

Before replacing an SRAM module, be sure to back up the

contents of the SRAM module.

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.

2. HARDWARE

B-64115EN/02

Part programs, offset data, and system parameters are stored in CMOS

2.10

memory in the control unit. The power to the CMOS memory is backed

REPLACING

up by a lithium battery mounted on the front panel of the control unit. The

BATTERY

above data is not lost even when the main battery goes dead. The backup

battery is mounted on the control unit at shipping. This battery can

maintain the contents of memory for about a year.

When the voltage of the battery becomes low, alarm message “BAT”

blinks on the display and the battery alarm signal is output to the PMC.

When this alarm is displayed, replace the battery as soon as possible. In

general, the battery can be replaced within two or three weeks, however,

this depends on the system configuration.

If the voltage of the battery becomes any lower, memory can no longer

be backed up. Turning on the power to the control unit in this state causes

system alarm 910 (SRAM parity alarm) or 935 (SRAM ECC error) to

occur because the contents of memory are lost. Clear the entire memory

and reenter data after replacing the battery.

The following two kinds of batteries can be used.

D Lithium battery built into the CNC control unit.

D Two alkaline dry cells (size D) in the external battery case.

NOTE

A lithium battery is installed as standard at the factory.

WARNING

Using other than the recommended battery may result in the

battery exploding. Replace the battery only with the

specified battery (A02B-0200-K102, A20B-0309-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 3.4 or C.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.

For separate battery unit

1) Prepare two alkaline dry cells (size D) commercially available.

2) Turn on the power to the control unit.

3) Remove the battery case cover.

4) Replace the cells, paying careful attention to their orientation.

5) Reinstall the cover onto the battery case.
