PANEL i

4.6.1

Replacing the Battery

The BIOS settings for the PANEL i are held in the LSI device on the PANEL i main board. The power

for this LSI device is backed up with a backup battery mounted on the PANEL i. Even if the main power

is interrupted, no data in the LSI device will be lost.

If the battery voltage drops, the BIOS message “CMOS Battery Low” appears on the screen when the

power is turned on. If the hardware monitor (HardMntr.exe) has been incorporated normally, the monitor

screen automatically opens to display “CMOS Battery : Low” after system start-up. If the alarm is issued,

replace the battery as soon as possible.

If the battery voltage drops further, it becomes impossible to back up the BIOS settings, thus making it

necessary to clear and re-set all the contents. For this reason, FANUC recommends that the battery be

replaced once per year regardless of whether a battery alarm is issued.

REPLACING BATTERY FOR ABSOLUTE PULSECODERS

4.7.1

Overview

• When the voltage of the batteries for absolute Pulsecoders becomes low, alarm 307 or 306 occurs,

with the following indication in the CNC state display at the bottom of the CNC screen.

Alarm 307 (alarm indicating the voltage of the battery becomes low) :

The indication "APC" blinks in reversed display.

Alarm 306 (battery zero alarm) :

The indication "ALM" blinks in reversed display.

• When alarm 307 (alarm indicating the voltage of the battery becomes low) occurs, replace the

battery as soon as possible. In general, the battery should be replaced within one or two weeks,

however, this depends on the number of Pulsecoders used.

• When alarm 306 (battery zero alarm) occurs, Pulsecoders are reset to the initial state, in which

absolute positions are not held. Alarm 300 (reference position return request alarm) also occurs,

indicating that reference position return is required.

• In general, replace the batteries periodically within the service life listed below.

A06B-6050-K061 or D-size alkaline dry cells (LR20) : Two years

(for each six-axis

configuration)

A06B-6114-K504 : One year (for each three-axis configuration)

NOTE

The above values indicate the estimated service life of batteries used with

FANUC absolute Pulsecoders. The actual battery service life depends on the

machine configuration based on, for example, detector types. For details, contact

the machine tool builder.

4.7.2

Replacing Batteries

To prevent absolute position information in absolute Pulsecoders from being lost, turn on the machine

power before replacing the battery. The replacement procedure is described below.

<1> Ensure that the power to the servo amplifier is turned on.

<2> Ensure that the machine is in the emergency stop state (the motor is inactive).

<3> Ensure that the DC link charge LED of the servo amplifier is off.

<4> Detach the old batteries and attach new ones.

The replacement of the batteries in a separate battery case and the replacement of the battery built into the

servo amplifier are described below in detail.

- 316 -

B-64485EN/01

4.MAINTENANCE OF THE OTHER UNITS

WARNING

• The absolute Pulsecoder of each of the αi/αi S series servo motors and the βi S

series servo motors (βi S0.4 to βi S22) has a built-in backup capacitor.

Therefore, even when the power to the servo amplifier is off and the batteries

are replaced, reference position return is not required if the replacement

completes within less than 10 minutes. Turn the power on and replace the

batteries if the replacement will take 10 minutes or more.

• To prevent electric shock, be careful not to touch metal parts in the power

magnetics cabinet when replacing the batteries.

• Because the servo amplifier uses a large-capacitance electrolytic capacitor

internally, the servo amplifier remains charged for a while even after the power is

turned off. Before touching the servo amplifier for maintenance or other

purposes, ensure your safety by measuring the residual voltage in the DC link

with a tester and confirming that the charge indication LED (red) is off.

• Be sure to replace the batteries with specified ones. Pay attention to the battery

polarity. If a wrong type of battery is used or a battery is installed with incorrect

polarity, the battery may overheat, blow out, or catch fire, or the absolute

position information in the absolute Pulsecoders may be lost.

• Ensure that the battery connector is inserted in the correct position.

4.7.3

Replacing the Batteries in a Separate Battery Case

Use the following procedure to replace the batteries in the battery case.

<1> Loosen the screws on the battery case and detach the cover.

<2> Replace the batteries in the case (pay attention to the polarity).

<3> Attach the cover to the battery case.

4.MAINTENANCE OF THE OTHER UNITS

B-64485EN/01

CAUTION

• Purchase the battery from FANUC because it is not commercially available. It is

therefore recommended that you have a backup battery.

• When the built-in battery is used, do not connect BATL (B3) of connector

CXA2A/CXA2B. Also, do not connect two or more batteries to the same BATL

(B3) line. These connections are dangerous because battery output voltages

may be short-circuited, causing the batteries to overheat.

• Install the battery in the servo amplifier in a direction that allows slack in the

cable. If the battery cable is under tension, a bad connection may occur.

• If the +6 V pin and 0 V pin are short-circuited, the battery may overheat, blow

out, or catch fire, or the absolute position information in the absolute

Pulsecoders may be lost.

• When inserting the connector, align it to the connector pins.

[Connecting the battery]

The battery for the βiSV4 and βiSV20 series amplifiers is mounted in the battery case on the underside of

each of the amplifiers.

The battery for the other βi series amplifiers and the αi series amplifiers is mounted at the front of each of

the amplifiers.

AUTOMATIC DATA BACKUP

It is possible to back up data held in the CNC’s FROM/SRAM by storing it automatically in the FROM,

which requires no battery and to restore the baked-up data as required. If data is lost from the CNC due to

unforeseen circumstances, this function can be used to restore the data easily.

Also, it is possible to hold up to three occurrences of backup data. With this function, the CNC data can

be quickly switched to a post-machine adjustment state or an arbitrary backup state.

Explanation

Data to be backed up

Data in the CNC is backed up by storing it in the FROM, which requires no battery.

• NC programs and directory information held in the FROM (which requires no battery)

• Various types of data, such as parameters and offset values, held in the SRAM (which requires

batteries)

Setting bit 2 (AAP) of parameter No.10340 to 1 enables NC programs and directory information in the

FROM to be backed up. Set this parameter only when necessary, because the required backup time and

data storage size vary depending on the size of the programs.

Setting parameter No. 10342 enables up to 3 occurrences of backup data to be held.

Backup modes

The following three backup modes are available.

Automatic backup occurring every time the power is turned on

Automatic backup occurring at intervals of a specified number of days when the power is turned on

Backup started manually at an emergency stop

Automatic backup occurring every time the power is turned on

Data in the CNC can be backed up automatically when the power is turned on.

This mode can be used by:

• Setting bit 0 (ABP) of parameter No. 10340 to 1

• Setting parameter No. 10342 to 1 or greater

- 327 -

5.INPUT AND OUTPUT OF DATA

B-64485EN/01

• Setting bit 2 (AAP) of parameter No. 10340 to 1 if also NC programs and directory information in

the FROM must be backed up

Automatic backup occurring at intervals of a specified number of days when

the power is turned on

Data in the CNC can be backed up automatically when the power is turned on for the first time in a

specified number of days since the previous backup.

This mode can be used by:

• Selecting the first backup mode (automatic backup occurring every time the power is turned on)

• Setting parameter No. 10341 with a number of days at intervals of which automatic backup is to be

made cyclically

Backup started manually at an emergency stop

Data in the CNC can be backed up by starting an appropriate procedure manually in an emergency stop

state. This mode makes it possible to back up data without turning off the power for the CNC at an

arbitrary timing, such as when machining has been set up or before a holiday.

This mode can be used by:

• Setting parameter No. 10342 to 1 or greater

• Setting bit 2 (AAP) of parameter No. 10340 to 1 if also NC programs and directory information in

the FROM must be backed up

[Backup procedure]

Put the machine in an emergency stop state.

Set bit 7 (EEB) of parameter No. 10340 to 1 to start backup. This parameter becomes 0 just after the

backup sequence has started.

The execution status of backup can be checked with No. 1016 on the diagnosis screen described

later.

NOTE

It takes time since the beginning of backup till the end of backup. So, if data being

backed up is updated, it is likely that a mismatch may occur between the original

data and backup data. When updating data in the CNC at an emergency stop,

watch the automatic data backup in-progress signal ATBK and perform

appropriate processing.

Backup execution status

In the backup modes used at power-on time, 10 dots “.” are used to indicate the execution status of

backup. For example, the completion of backup is indicated with: “AUTO BACKUP : ……….END

The diagnosis screen can also be used to check the execution status of backup as follows:

• No.1016#0 (AEX): Backup in progress

• No.1016#6 (ACM): Backup completed

• No.1016#7 (ANG): Error during backup

• No.1016#1 (DT1), #2 (DT2), #3 (DT3): Updated data

Write-protected backup data

Factory-set or post-adjustment machine status data can be held as write-protected backup data by

specifying the number of pieces of backup data to 2 or greater with parameter No. 10342. The first piece

of backup data is handled as write-protected backup data.

This function is enabled by:

• Setting bit 1 (ABI) of parameter No. 10340 to 1

• Setting parameter No. 10342 to 2 or greater

• Setting bit 2 (AAP) of parameter No. 10340 to 1 if also NC programs and directory information in

the FROM must be backed up

- 328 -

B-64485EN/01

5.INPUT AND OUTPUT OF DATA

[Backup procedure]

Set bit 6 (EIB) of parameter No. 10340 to 1.

Turn the power for the CNC off and on again. When the power is turned on, the first piece of backup

data is updated automatically, and bit 6 (EIB) of parameter No. 10340 becomes 0.

The second and third pieces of backup data are updated each time another type of backup (automatic

backup occurring every time the power is turned on, automatic backup occurring at intervals of a

specified number of days when the power is turned on, or backup started manually at an emergency stop)

is made.

Parity check

A parity check is made at backup. If a parity error is detected, the backup is not completed.

Restoring backed-up data

With the BOOT SYSTEM, executing the following procedure can restore backed-up data from FROM.

From the BOOT’s TOP menu, select “7. SRAM DATA UTILITY”. The following menu appears.

Select ”3”.

6.1

WHAT IS PMC?

The programmable machine controller (PMC) is a programmable controller (PC) built into a CNC to

perform sequence control for a machine tool (spindle rotation, tool change, machine operator's panel

control, and so on).

Sequence control is to perform control steps successively in a predetermined sequence or according to the

logic operation.

Programs for performing sequence control for machine tools are called sequence programs. Generally,

sequence programs coded in the Ladder language are used.

The sequence program reads input signals, performs operations, and outputs results in a predetermined

sequence.

6.1.2

I/O Signals of PMC

Input signals of the PMC include signals input from the CNC (such as M and T function signals) and

signals input from the machine (such as the cycle start button and feed hold signal button). Output signals

of the PMC include signals output to the CNC (such as the cycle start command and feed hold signal

command) and signals output to the machine (such as turret rotation and spindle stop). The PMC controls

these I/O signals by executing a sequence program to control the machine tool.

Communication Method for External I/O Device

For the high-speed serial interface, which passes input/output signals between the PMC and each I/O

device, there are two communication methods, i.e. the FANUC I/O Link i and the FANUC I/O Link.

You can use up to three channels for the serial interface. The communication method for channel 1 and

channel 2 can be specified by the CNC parameter. The default value “0” of the CNC parameter means

that I/O Link is specified. The channel 3 can be used only for I/O Link.

For the details of the setting of the CNC parameter, see PMC PROGRAMMING MANUAL

(B-64513EN).

MULTI-PMC FUNCTION

The multi-PMC function allows one PMC system to execute multiple sequence programs at the same

time.

PMC memory for each sequence program is basically independent, and the same PMC address can be

used for different purposes of the individual PMCs. Extra relays (E addresses) can be shared among

PMCs as shared memory. All PMCs can read from and write to this area, so the area can be used for the

interface between the PMCs. M,N addresses can be also used for the interface between the PMCs.

A program for each PMC is saved as an independent file and can be edited, updated, and backed up

separately.

The CNC systems and the I/O Link channels to be controlled by PMCs can be changed by CNC

parameter setting. In a parameter-set configuration, one PMC may control all CNC systems, or each PMC

may control a different CNC system.

Fig. 6.2 (b) shows a configuration example.

If the Series 30i/31i/32i-A system is used to control more than one CNC path, some paths can be grouped

to share data within a group and to stop all the paths in the group if an alarm condition occurs in one of

the paths. The group is referred to as the machine group.

The system supports up to 3 machine groups. Each group has a separate emergency stop signal address.

A PMC is basically assigned to each machine group.

6.2.1

Execution Order and Execution Time Percentage

For the multi-PMC function, the order of PMC execution and execution time percentages of the PMCs

can be set with CNC parameters.

6.2.3

Interface Between CNC and PMC

The PMC to control the interface between the CNC and PMC and PMC addresses (F/G addresses) can be

set with CNC parameters.

With these parameter settings, a desired interface control system can be built, in which the entire

CNC-PMC interface of the CNC may be controlled by a single PMC or the CNC-PMC interface may be

controlled by multiple PMCs.

For the CNC-PMC interface, a memory area consisting of 10 blocks, each of which is an addressable,

768-byte DI/DO area, is provided.

When viewed from the ladder program in each PMC, these addresses begin with 0.

If these parameters are not set (0 is set), the initial settings are assumed, where the F/G addresses of the

CNC equals the F/G addresses of the first PMC as Fig. 6.2.3 (a):

Multi-Path PMC Interface

The multi-path PMC interface is the communication means between two PMC paths.

Generally, Each path of multi-path PMC system has individual PMC memory space except E address.

And, E address can be used to share data of multi-path PMC system. However, this method has a risk that

the memory is over written by other PMC path inappropriately.

When using this function, the input and output signals of each path become definitely. So, you can send

or receive the data on between two PMC paths safely.

When you output data to N address at one of PMC paths, it can be referenced by M address in other PMC

path.

NOTE

This interface does not support the fourth or fifth PMC path.

6.INTERFACE BETWEEN CNC AND PMC

Ex.) When using this function with 1st PMC and 2nd PMC :

1st PMC

2nd PMC

Moreover, signals of M address are synchronized during 1 scan of 2nd level program. Therefore, you can

reference the same signal status on the first step and the last step of level2 program, like as X and F

address.

System Relay Addresses (R9000, Z0)

The System Relay is used to control a sequence program by PMC System software. And, some addresses

such as 'Operation results of functional instructions' are used to condition of a sequence program.

The System Relay uses the following PMC address by each PMC Memory Type.

NOTE

Ladder conversion from PMC memory A or B to PMC memory C or D requires

converting System Relay addresses.

Operation results of functional instructions

This area holds information necessary for individual ladder levels, such as the operation results of

functional instructions. This information is saved/restored when the task is switched.

(1) R9000, Z0 (operation output register for the ADDB, SUBB, MULB, DIVB, and COMPB functional

instructions)

R9000

The result is 0.

The result is negative.

The result has overflowed.

(2) R9000, Z0 (error output for the EXIN, WINDR, and WINDW functional instructions)

R9000

The result is erroneous.
