COUNTERMEASURES AGAINST NOISE

The CNC has been steadily reduced in size using surface-mount and custom LSI technologies for

electronic components. The CNC also is designed to be protected from external noise. However, it is

difficult to measure the level and frequency of noise quantitatively, and noise has many uncertain factors.

It is important to prevent both noise from being generated and generated noise from being introduced into

the CNC. This precaution improves the stability of the CNC machine tool system.

The CNC component units are often installed close to the parts generating noise in the power magnetics

cabinet. Possible noise sources into the CNC are capacitive coupling, electromagnetic induction, and

ground loops.

When designing the power magnetics cabinet, guard against noise in the machine as described in the

following section.

4.9.1

Grounding

Grounding the power magnetics cabinet and devices is very important to prevent an electric shock and

suppress a noise influence. The following describes the grounding methods for suppressing the noise

influence.

4.9.1.1 About grounding types

The CNC system uses the following three types of grounding:

(1) Signal grounding

This type of grounding is used to supply a reference potential (0 V) for the electrical signal system.

(2) Frame grounding

This type of grounding is used for safety reasons as well as to suppress external and internal noise.

For example, grounding is provided for the device frames, panels, and shielding on the interface

cables connecting the devices.

4.MATTERS COMMON TO BOTH LCD-MOUNTED TYPE

B-64305EN/03

AND STAND-ALONE TYPE (HARDWARE)

(3) System grounding (PE)

This type of grounding is used to connect frame grounds, which are provided for the individual

devices or between the units, to the ground as a system at a single point.

4.9.1.2 Grounding methods

Typically, noise that becomes a problem is high-frequency noise. To suppress high-frequency noise, it is

important that the devices are grounded at low impedance^(NOTE).

The grounding schemes for this purpose are described below.

(1) Multipoint grounding scheme

In this grounding scheme, when grounded at sufficiently low impedance, the cabinet metal plates are

used as ground plates, to which grounding is provided in the vicinity of each device.

This scheme has a great effect of suppressing high-frequency noise because it enables grounding to

the low-impedance metal plates of the cabinet in the shortest distance. However, the noise

suppression effect depends on the cabinet structure because the cabinet metal plates are used as

ground plates.

See Subsection 4.9.1.4 for the cabinet. Fig. 4.9.1.2 (a) is a schematic wiring diagram.

When the multipoint grounding scheme is adopted, the units can be grounded at low impedance, and

ground wires can be shortened, so that wiring may be simplified.

(2) Single-point grounding scheme

In this grounding scheme, grounding separation is achieved between the signal system and power

system, and grounding is provided at a single point to suppress the noise influence of the power

system on the signal system.

This scheme tends to need longer connection wires for grounding the devices. To produce a

sufficient effect of suppressing high-frequency noise, it is therefore necessary to use larger-diameter

wires or use two or more wires for each connection. Fig. 4.9.1.2 (b) is a schematic wiring diagram.

NOTE

Impedance includes a resistance component that converts electric current to

heat as well as a component called “reactance”, and indicates a characteristic of

resistance to the flow of alternating current at a certain frequency.

B-64305EN/03

4.9.1.3 Cable clamp and shield processing

Signal lines basically require shield clamps. The influence of external noise can be suppressed by

properly providing the signal lines with the shield clamps.

Partially peel the sheath off a cable and expose the shield, and press the exposed portion against the

ground bar with the clamp. Care should be taken so that the ground bar and shield have a surface contact

in a larger area. (See the figure below.)

When the multipoint grounding scheme is used, care should be taken so that the ground bar for the shield

clamp and cabinet are connected at low impedance by, for example, preventing the cabinet side contact

surface from being coated.

Cable

Metal fittings for

clamp

NOTE

Select a cable with a proper length.

If the cable is too long, the noise immunity may be reduced or noise may be

caused on other cables. In addition, when the excess length is coiled, the

inductance is increased and a high voltage is induced during turning on or off of

signals. This may cause a malfunction due to a failure or noise.

B-64305EN/03

AND STAND-ALONE TYPE (HARDWARE)

4.9.1.4 Cabinet

A cabinet is an important element in improving noise immunity and suppressing radiated noise. One of

the causes of problems related to noise immunity and radiated noise is faulty electrical continuity between

the metal plates that make up the cabinet. Typically, noise that becomes a problem is high-frequency

noise, against which measures must be taken in the cabinet design.

(1) Basic cabinet structure

A cabinet should basically be made of metal.

To improve noise immunity, there must be low-impedance electrical continuity between the metal

plates that make up the cabinet, which are the side plates, top plate, and bottom plate, and a

welding-type cabinet structure is recommended.

As for a cabinet welding method, bead welding is more suitable than spot welding for providing

low-impedance electrical continuity between the metal plates.

For an assembly-type cabinet structure, provide electrical continuity by bringing the metal plates

into direct contact with each other, without applying a coating to their joint surface areas.

In a structure that has the metal plates connected only with wires because of structural constraints,

low-impedance connections are more difficult to make than in a structure in which welding is made

or the metal plates are brought into direct contact with each other. It is necessary to maintain

sufficient levels of items such as the cross-sectional area of a wire to use, continuity of connections,

and contact areas.

Bead welding

Bring the metal plates into direct contact with each

other, without applying a coating to their joint areas.

NOTE

For improved noise immunity, how to provide low-impedance electrical continuity

in the cabinet is described here. To construct a protective circuit, a protective

grounding connection must be made between the metal plates by using electric

wires with a cross-sectional area appropriate for the AC input power capacity of

the unit mounted on each metal plate.

(2) Mounting units on the cabinet

The shortest possible lengths of unit ground wires should be used to make connections. A ground

wire with a small conductor diameter causes impedance to high-frequency noise to become

particularly higher, leading to an insufficient grounding effect. For the location of the ground

terminal of each unit, refer to the manual relevant to the unit. The following shows the

recommended method by which the metal plate with the unit mounted is installed on the cabinet.

Care should be taken so that the cabinet and metal plate are connected to each other on their broad

areas with no coating. It is not recommended that electrical continuity be provided only by screws,

because impedance to high frequency cannot be sufficiently low.

Connecting the Ground Terminal of the Control Unit

Connecting the 0 V output in the CNC to a protective circuit (ground)

The IEC 204-1 and JIS B 6015 standards specify the following:

- Protection against malfunctions due to ground faults

“To make the control circuit prevent malfunctions of a machine tool due to a ground fault and not to

prevent the machine tool from stopping, either of the ground and electronic circuits shall be connected to

a protective circuit.”

Note that for each FANUC CNC, the 0V output in the CNC is connected to a protective circuit (ground).

Noise Suppressor

The AC/DC solenoid, AC/DC relay, and other devices are used in the power magnetics cabinet.

A high pulse voltage is caused by coil inductance when these devices are turned on or off.

This pulse voltage is induced through a cable or any other component, causing the electronic circuits to be

disturbed.

Take the following measures against the pulse voltage:

See Subsection 4.9.3 for groups A and B, and use spark killers for AC circuits or diodes for DC

circuits.

See “Notes on selecting the spark killer” below for information about selection of spark killers or

diodes.

Notes on selecting the spark killer

• Use a CR-type spark killer. (Use it for AC circuits.)

(A varistor is useful in clamping the peak pulse voltage, but cannot suppress the sudden rise of the

pulse voltage. FANUC therefore recommends the use of a CR-type spark killer.)

• The reference CR values of the spark killer shall conform to the following based on the current ((I

4.10 REPLACING BATTERY FOR ABSOLUTE PULSECODERS

4.10.1 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-6073-K001 : Two years (for each three-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.

4.10.2 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.

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.

4.10.3 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.

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.

4.11 CAUTIONS IN REPLACING PCB’S

This CNC supports the “FANUC Remote Option System.”

There are several cautions that should be observed in replacing printed circuit boards. Follow the

replacement procedure below.

PCB replacement procedure

Optional parameters are stored in an option information file (with file name “OPRM INF”) in the

FROM module.

Before replacing a printed-circuit board, back up the optional information file as well as SRAM data

and user files as usual. If the optional information is corrupted during replacement, the backed-up

data will become necessary in recovery work.

As usual, after replacing a printed-circuit board, restore the SRAM data and user files as required.

If the FROM/SRAM module is replaced, it is necessary to restore the optional information file that

was held in the FROM module. Use the data backed up at step 1). Once restoration is finished,

alarm PS5523 "Option authentication wait state" will occur when the power is turned on. It is

necessary to access FANUC’s web site and perform optional parameter authentication work with the

"FANUC Remote Option System" within the period of validity (within 30 days since the occurrence

of the alarm).

(Within the period of validity, alarm PS5523 can be canceled by a reset.)

Replacing a printed-circuit board may result in a change to the CNC ID number. Check it on the

CNC screen. If it is different from one described on the data sheet, correct the data sheet.

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 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.

NOTE

Automatic data backup function is optional function.

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 held in the FROM (which requires no battery)

- 189 -

5.INPUT AND OUTPUT OF DATA

B-64305EN/03

• 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 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.

Also, it is possible to hold three occurrences of backup data.

- 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 bit 2 (AAP) of parameter No. 10340 to 1 if also NC programs in the FROM must be backed

- 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.

If you want to back up NC programs in the FROM, set bit 2 (AAP) of parameter No. 10340 to 1 before

backup operation.

[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

- 190 -

B-64305EN/03

5.INPUT AND OUTPUT OF DATA

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): Numbers of updated backup data items

- Write-protected backup data

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

piece (data 1) 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 bit 2 (AAP) of parameter No. 10340 to 1 if also NC programs in the FROM must be backed

[Procedure for creating write-protected data]

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.

Then, the first backup data is handled as write-protected data until the same operation is performed again.

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”.

SRAM DATA UTILITY

1.SRAM BACKUP

( CNC -> MEMORY CARD )

2.SRAM RESTORE ( MEMORY CARD -> CNC )

3.AUTO BKUP RESTORE ( FROM -> CNC )
