1. Forewords
In EU, the EMC Directive became mandatory on 1. January 1996. To show the
conformity, CE marking is required to apply on products. As it is known, the CE mark
is primarily for final products for users. FANUC’s CNCs and amplifiers are essentially
parts of machine tools, nevertheless, considering various situations like FANUC
exports those products directly to EU, FANUC has decided to display the CE mark in
those products (hereafter referred as FANUC products).
However, by the following reasons, the CE marking of FANUC products does not
certify that a machine equipped with FANUC products conforms to the EMC Directive.
1) The CE mark of FANUC products assumes that the products are installed to fulfill
certain conditions. Therefore MTBs have to install the products as requested in the
conditions.
2) Normally, a machine tool has electric equipment from other vendors than FANUC.
For that equipment, an MTB is supposed to take appropriate countermeasure to meet
the EMC Directive requirement if necessary.
Therefore, as we experienced in case of the Machinery Directive, MTBs are
responsible for displaying CE mark in machines in relation with EMC Directive as
well.
However, having certificates of conformity to the EMC relating standards on
FANUC products might help the MTB get the EMC conformity's certificates for their
machine or machine series more effectively, as describes in the following chapter.
This document is installation guideline for MTBs to design a machine tool
equipped with FANUC products. We believe MTBs can get machines certified if they
follow this document.
The contents of this guideline subject to are changed without notice depending on
any situation.

2. Conformity evaluation test
In September 1995, the generic immunity standard (EN50082-2) was harmonized
by EU. Consequently, a manufacturer can declare, by themselves, product conformity
to the EMC Directive by indicating the product meets relevant harmonized standards.
2.1 Items of conformity test for FANUC products
FANUC has been working with a German CB (Competent Body) before the
harmonized standards issued and we have prepared for declaration of conformity by
getting the CB’s certificate. FANUC products actually clear the following tests.

2.2 Certification for a machine series
When an MTB intends to get a CB's EMC certificate for their machine, it is said
possible that the MTB can get the certificate for their machine including a machine
series through a documentation based inspection if they construct their machines
strictly following the stipulations of each EMC relating component and those
components are all certified ones.
On the other hand, if they applied other methods than stipulated by some
components, a MTB shall conduct all or some of above listed evaluation tests
depending on the cases for at least one representative model.
Even in this case, the certification process can be reduced if they use only certified
components. In this case they need to submit the technical writings of justification on
electromagnetic equivalency between their tested machine model and other models
within the machine series.
3. Guidelines for electric design
As the biggest concern is how we can get our products to pass the test, this
document concentrates in this point
From MTB’s viewpoint, we can classify the tests listed in the previous section as
follows.
Group 1
1) Radiated emission
Group 2
3) Conducted emission
Group 3
2) Radiative susceptibility
4) Conductive susceptibility
5) Electrostatic discharge
6) Fast transient (burst)
7) Surge
8) Voltage variation

As to the test items in the group 3, as far as FANUC products are concerned, it is
OK to take the conventional countermeasure (unit grounding, shield grounding and so
forth) that has been described in ordinary connection manuals. (To pass the tests,
FANUC modified the products. The units modified are listed in the annex 1.)
As to the conducted emission in the group 2, the countermeasure is just a noise
filter. If the recommended filter is used, a machine will get the test passed. Though
this is new item, it isn’t technically difficult except for space needed.
Radiated emission in the group 1 is most difficult. FANUC modified products (see
annex 1) and MTBs need to take quite some new countermeasure on top that. This
document describes new countermeasure later and most of them are for the radiated
emission.
FANUC’s products are so called “electronic equipment” and they have some
oscillators as listed below.
(1) Switching of NC power supply unit
(2) Clock of NC logic circuit
(3) Switching of α-series power supply module
(4) Switching of α-series amplifier
These oscillators induce oscillating voltage in conductive materials (cables, metals
not grounded etc.) inside of a cabinet and those conductive materials become antenna
and emit electric wave. As mentioned earlier, FANUC modified the products to have
less noise emitted. However, MTBs also need to take countermeasure. The
countermeasure is fundamentally as follows.
1) Units that have oscillators in it should be put in an enclosed metal cabinet.
2) Ground all the conductive stuffs that are electrically floating.
3) Stuffs that could be antenna (e.g. signal cable with high frequency) should be
surrounded by grounded metal. (Shielding)
The countermeasure for EMC issue is very delicate. Narrow gaps, condition of
cable shielding and other conditions influence on the result largely. Bear in mind this
situation and take the countermeasure as strictly as possible.

EMC_GL_9.DOC
A-72937E
3.1 Cabinet
Cabinets are, as well as cables, most important element to eliminate radiated
noise. If our products are put in a totally enclosed metal box with no hole, it will pass
the test. But it is not realistic because we need a door, holes for cable inlet and outlet,
holes for unit mounting and others. Electric wave gets out through these holes and it
prevents products from passing the test. Therefore, the point is how to close the holes
electrically.
3.1.1 Fundamental consideration about cabinets
A basic condition is cabinets should be made of metal. Then, connection between
walls, floor and ceiling is by welding or, in case of screw assembling type cabinet, is
sure to eliminate paint in the contact area to have conductivity.
3.1.2 Treatment of gaps
In case of screw assembling type cabinets, a gap at connecting portion is the issue.
Even if there is no mechanical gap, electric wave can come out if the walls are painted
because there is electric gap. As described in section 3.1.1, eliminate paint in the
contact area to get electric contact. Further, it could happen screwing bends a panel.
Pay attention to this problem as well. Normally there is no problem in welding type
cabinets.
3.1.3 Biggest allowable hole
Size of minimum hole where electric wave can go through differs dependently on
wavelength. It is said the guideline is a tenth of the wavelength. The regulated
frequency in the EMC Directive is from 30MHz to 1GHz. Also it is known, from the
experience, level of electric wave come out of the cabinet is very small in frequency of
300MHz or higher, when FANUC products are put in a metal cabinet. Wavelength of
300MHz electric wave is 1m and a tenth of that is 10cm. Therefore, 10cm is a
maximum diameter of allowable holes and take countermeasure to close them if holes
are bigger than 10cm.
7
EMC_GL_9.DOC
A-72937E
3.1.4 Close holes electrically　“Close holes electrically” means to use conductive stuff (normally metal) as a cover
and the cover is connected to a cabinet in low impedance. The following is the standard
configuration. 。
That is, eliminate paint from circumference of a cover and a cabinet hole to get
conductivity between them. The followings are bad examples.
(1) A cover is made of non-conductive material like plastic.
(2) Metal is used, but either or both of a cover and a cabinet is painted.
(3) A cover and a cabinet are connected through a wire. (No contact by surface)
(4) By some reason like a cover is too thin, the cover is bent and it gets gap when it
is screwed.
Pay attention especially to a gap. Even 1mm gap leaks electric wave if the length is
big.
3.1.5 Door
A door gives a biggest hole in a cabinet. It is important to eliminate a gap by good
combination between a door and a cabinet so that no electric wave can come out.
1
A door should be made of metal.
2
Use conductive gasket between a door and a cabinet. Eliminate paint from the
area the gasket is applied in both of a door and a cabinet. (The conventional way
to connect a door and a cabinet by thick wire is not enough.)
3
Not get any gap between a door and a cabinet.
8
EMC_GL_9.DOC
A-72937E
To FANUC’s knowledge, available gasket from the market is questionable in
sealing performance (IP54) and also in industrial environment use. Therefore, FANUC
recommends to use two gaskets in parallel, one is conventional gasket good for
industrial environment use and the other is conductive gasket. (See below) In such
case, pay attention so that the conductive gasket gets suitable contact between a door
and a cabinet.
Door
Conventional gasket
Conductive gasket
3.1.6 Eliminate conductive stuffs floating electrically
As described earlier in this chapter, be sure to ground conductive stuffs that are
floating electrically in a cabinet. Those floating stuffs are easily influenced by electric
wave and they immediately act as antenna. Metal fittings prepared for mounting of
units and shield cables used because of availability of materials although they need
not to be tend to be overlooked. Pay attention to those stuffs especially.
3.1.7 Operation box
Pay attention to the following points in designing an operation box where an
operator’s panel like CRT/MDI is installed.
1
A faceplate of operator’s panel should have paint removed at flange portion so that
the faceplate has electric contact toward the operation box. Of course the operation
box needs to have same construction, that is, paint must be removed around the
mounting hole. For mounting, use conductive gasket.
2
When the box has a door, use a conductive gasket between the box and the door
and make sure to have tight electric contact in between when the door is closed.
This is the same consideration as a main cabinet.
3
As described in Chapter 4, shield of video signal cable needs to be grounded at the
operator’s panel side as well. Therefore, the operation box should have cableclamping system in it. (See section 4.1)
9
EMC_GL_9.DOC
A-72937E
4
Tie the cabinet and the box by a thick ground wire, unless those two are connected
tightly through a machine body or a part of the main cabinet.
3.1.8 Separation of input power portion
In a magnetics cabinet, there are units that emit noise and the cabinet is, so to
speak, filled with electric wave. Therefore, cables come out of a cabinet are influenced
by them directly and/or indirectly and the cables are just like antenna to emit electric
wave. If those cables come out without any countermeasure, they emit big noise and a
system does not get the test passed. This section describes about the input power
portion of the cabinet. Cables are described in chapter 4 in detail.
As it is easily understood, a problem we are going to solve in this section is the noise
emitted by power input cable going out of a cabinet. As it is difficult to take
countermeasure like shielding in power input cables, we separate the input power
portion from other portion of a cabinet so that the input power cable is not
contaminated by noise inside the cabinet. See the drawing below.

In the above drawing, cables shown by thick lines should be clean because noise is
eliminated by a noise filter. But, noise (electric wave) shown by dotted line
contaminates the cables and the cables are noisy again.

In order to prevent such situation, we separate the cabinet into two portions, that is,
before the noise filter and after the noise filter as shown below.

3.2 Noise filter
Noise filters are indispensable in countermeasure for EMC. FANUC worked to select
suitable noise filters and, as a result, FANUC recommends the following filters.
Choose a right filter according to a power supply module used and put it just after the
input breaker shown in section 3.1.8.

3.4 Spark killers
Be sure to provide spark killers to all the inductive equipment. FANUC recommends
CR network for AC circuit and diodes for DC circuit. Varistors just cut the peak
voltage and the steep rising edge of voltage remains as it is, so it is not recommended.
3.5 Grounding of equipment
All the equipments should be grounded as the vendors recommend regardless to the
location the equipments are installed (inside/ outside of the cabinet).

4. Cables
Cables are very important in the EMC countermeasure because they influence a lot
in emitted noise level. As mentioned earlier, the cables come out of a magnetics cabinet
have high frequency noise, more or less. If no countermeasure is taken for that, the
cables act as antenna and they emit large level noise. The problem is not only for
signal cables but also for power cables.
It is essential to take countermeasures as far as possible so that cables get less noise
in a cabinet and emit less noise out side of the cabinet. Though it is conventional,
shielding of cables is a primary countermeasure. Also ferrite cores are effective in some
cases. And it is also effective to put cables close to metal wall of cabinet in some cases.
FANUC did a lot of experiment and determined ways to make cables in each use.
The ways are described in section 4.3 and also a summary table in the annex 2. Please
have a look at the table as well. FANUC would like machine tool builders to follow the
way. Please have a look at the table in the annex 5 for Servo related cables also.
4.1 Grounding of shield (braided copper wire)
Shield (braided copper wire) should be grounded by cable clamps attached to a
FANUC CNC. The way to use the clamps are described in the connection manual of
each FANUC CNC. Please follow the way.
Where cables are connected between inside units and outside ones, fit the cabinet
with a ground plate (earth plate) for the cables near the inlet of the cables as close as
possible.
When one or two cables need to be grounded apart from other cables, the following
cable clamp is also available.
17
EMC_GL_9.DOC
A-72937E
This kind of clamp is available from Kitagawa Kogyo as FG-series clamps (parts
number FGC-3 and others) or from Osada (parts number　P01 and others).
It is not recommended to solder a vinyl copper wire to the braided wire and ground
it.
4.2 Ferrite core
FANUC recommends to use ferrite cores for the cables for display unit (CRT or LCD)
and also for the cables for serial port like RS232C. One of the available ferrite cores in
the market is ZCAT3035-1330 from TDK. According to their product brochure, the
outer dimension of the ferrite core is as follows. This is a shared type ferrite core put in
a plastic case and it is easy to install it even to assembled cables. E04SR301334 from
SEIWA Electric, the outer dimension is the same as follows, is also available.
It may be necessary to use ferrite cores to get the certificate from a competent body.
As to a location to put the cores in each cable, refer to section 4.3.
4.3 Detailed description of each cable
(1) Video cable (in case of CRT display)
Use coaxial overall shield cable for the video cable. FANUC introduced new video
cable (A66L-0001-0371) in Dec. 1994 and it is suitable for this. As to the new cable,
we issued a Technical Report (TMN 94/184) at that time. As to the details of the
cable, please see it as well.
The video cable should be constructed as follows. The ferrite core is as introduced in
section 4.2.

EMC_GL_9.DOC
A-72937E
(6) Power supply cable for display units (in case of CRT display)
Use conventional vinyl copper wire or cabtyre cable when the cable stays within a
cabinet or the cable goes to another cabinet or operation box through metal duct.
Use overall shield cable when the cable goes out of the cabinet without metal duct
and ground the shield at NC side.
(7) Power supply cable for display units (in case of display units other than CRT
display)
Similarly to the case of CRT display, use conventional vinyl copper wire or cabtyre
cable when the cable stays within a cabinet or the cable goes to another cabinet or
operation box through metal duct.
Use overall shield cable when the cable goes out of the cabinet without metal duct
and ground the shield at NC side.
Furthermore, use a ferrite core at the display side in the above both cases.
The following is an example in case that the cable goes out of a cabinet without
metal duct.

(8) MDI cable
Use conventional overall shield cable for the MDI cable. Ground the shield at NC
side.
(9) Cable of Manual Pulse Generator
Use conventional overall shield cable for the cable. Ground the shield at NC side.
(10) Servo command cable
Use conventional overall shield cable for the servo command cable. Ground the
shield at NC side. Up to now, there are some cases that no shield treatment is done
because it is only the internal cable in a cabinet and also the length is short.
However, from the viewpoint of noise emission, be sure to ground the shield.
20
EMC_GL_9.DOC
A-72937E
(11) Servo motor feedback cable
For servo motor feedback cables, use double layered shield cable. The double
layered shield cable is constructed as below.
Specification of the cable is A66L-0001-0405. This cable is also available from
Hitachi
Cable
Ltd.
and
Shinko
Electric
Industrial
Co.,
Ltd.
Shield treatment of the cable should be as follows.
1) Grounding of the cable should be done in the outer shield only. Leave the inner
shield open in both ends. Shield treatment of outer shield. Peal out the sheath in
the NC side and make contact with an earth plate by a cable clamp.
2) For the motor side please refer to the itemized discussion in the item (13).
By the way, as for the following each cable (feedback cable, power cable and spindle
power cable and fan cable), the assembled one with the connectors could be
provided as a cable assembly.
(12) Servo motor power cable
For servo motor power cables, use shield cables. One of those cables is available
with “OR-VV-SB” from Shinko Electric Industrial Co., Ltd., a Japanese cable
manufacturer. Shield treatment should be done as follows.
1) Servo amplifier side
Peal out the sheath in the amplifier side and make contact with an earth plate
by a cable clamp. Mount an additional grounding bar close to the cable inlet of
the magnetic cabinet. Connect the power cable shields to this grounding bar.
2) Motor side
Connect the shield wire to the ground through the ground terminal in the
connector that is led to the grounded motor body.
Detailed connection method is described in the following paragraphs in item
(13).

◎ The shield clamp adapter and bridge wire (FG mesh) are not necessary except
for the older version that either of the following conditions is met.
Conditions: 1. The motor employsα pulsecoder (Spec. No.: A06B-0***-B*75～B*77,
B*86～B*89) but its manufactured date is before May ‘96.
2. The motor employs SERIAL A pulsecoder. (Spec. No.: A06B-0***-B*84,B*85)
Note) The current motor, which does not meet any of above conditions, has the
feedback connector in which the contact ‘L’ has a connection with its shell
and motor body. That is why the connection of current signal cable does
not require using shield clamp adapter or FG mesh as is required below.
Feedback connector
Power connector
Shield clamp adapter
FG mesh
When either of above condition is met, apply the following two step measure
instead of connecting the shield to the contact ‘L’.
Firstly, connect the shield stranded wires to the connector-block for the motor
using a shield clamp with its clamp ring inside. Treat the shield wires and then
fix the cable by a cable clamp as illustrated above.
These shield clamp adapter, used between the connector-block and the cable
clamp, are available with connectors certified by TÜV from JAE (Japan Aviation
Electronics Industry Ltd.), Hirose Electric Co. Ltd. or DDK Ltd. The shield
clamp adapter, the connector-block and the cable clamp should be in
combination of the same manufacturer’s products.

Secondly, connect the feedback connector and the power connector by a bridge
wire. Use screws that fix the connectors of the motors for this connection
purpose. When there is a concern about the environment where the wire is
exposed to cutting liquid and so on, using a plated metal could be a solution for
that. “FG mesh: FGM-50-M3” which is manufactured by Kitagawa Industries
Co., Ltd. is available for this case.
b) Power cable
Use shield cable. Solder the shield wire and the earth wire to the ground contact
directly together. The drain wire or thinned out shield wire is available for this
case. The ground contact is connected directly to the connector case and is also
connected to the motor body by wiring.
4) β series servo motors (Model β1 to β6)
a) Feedback cable
Use double layered shield cable. Leave the both inner and outer shield open in
the motor end.
b) Power cable
It is the same as above (Model α3 and more). Please refer to that.
(14) Servo motor brake and fan cable
A shield cable is necessary as power cable when the CS test (Conducted Radiofrequency Immunity of Signal and Control Lines) is passed surely such case of the
cable is exposed to the outside of the machine. One of those cables is available with
“OR-VV-SB” from Shinko Electric Industrial Co., Ltd., a Japanese cable
manufacturer.

A-72937E
(15) Feedback cables for additional position detector
For the cables for additional position detector, use conventional overall shield pair
wire cable and ground the shield in NC side. Also, provide ferrite cores at both
ends.
(16) Spindle command cable (serial interface and analog interface)
For the spindle command cable, use conventional overall shield pair wire cable and
ground the shield in NC side. Up to now, there are some cases that no shield
treatment is done because it is only the internal cable in a cabinet and also the
length is short. However, from the viewpoint of noise emission, be sure to ground
the shield.
(17) Spindle power cable and fan cable
For spindle motor power cable and fan cable, FANUC recommends shield cable. In
the amplifier side, the shield treatment should be done by cable clamp to connect
with the earth plate. In the motor side, connect the shield to the ground terminal
inside the terminal box.
When a metal conduit with braided shield is used for the connection, it is OK to use
just a normal cabtyre cable. In this case, as the terminal box is not metal, it is
necessary to bring a metal fitting that is put in parallel with the plastic wall. The
metal fitting is grounded through a wire. See the following drawing.
For reference, a sample of drawing of such metal fitting is attached as annex 4.
For example, FAW, FCK (waterproof type) and FAE (waterproof type) of that metal
conduit are available from DAIWA DENGYO Co., Ltd.,
25
EMC_GL_9.DOC
A-72937E
(18) Spindle motor feedback cable (between motor and amplifier)
For the spindle motor feedback cable, FANUC recommends a double layered shield
cable. (see (11)servo motor feedback cable.) The amplifier side of the outer shield
should be connected with an earth plate by cable clamp. FANUC recommends that
the motor side of the outer shield is connected to the ground terminal of the
terminal box. The amplifier side of the inner shield should be connected to 0V of
PCB through a pin connector. (As for the pin number for 0V, please refer to the
Description of the spindle amplifiers.) The motor side of the inner shield should be
left open. When a metal conduit with braided shield is used for the connection, it is
OK to use conventional overall shield pair wire cable. In this case, shield treatment
of the braided shield of the conduit should be done similarly to that of spindle
power connection. Grounding of the cable shield is done not by the cable clamp but
by connecting to 0V of the PCB. For the details, see the Description of spindle
amplifier.
(19) Position coder cable
For the position coder cable, use conventional overall shield pair wire cable and
ground the shield in NC side.
When the position coder is installed at a place where an operator can touch it, it is
necessary to ground the position coder connector in order to have immunity against
electrostatic discharge. There are two ways for that.
1) Put a wire between the connector and ground. The connection to the connector
can be done by a screw that fixes the connector.
2) Similarly to the shield treatment of servo motor feedback cable, use the shield
clamp and make connection between the cable shield and cable connector. By
mating the cable connector with the position coder connector, the position coder
connector is grounded because the shield is grounded by cable clamp at NC side.
However, Where this cable is connected to analog input of FANUC series 16i/18i,
take above measures and also put a ferrite core in NC side.
26
EMC_GL_9.DOC
A-72937E
(20) Serial port cable (RS232C, RS422)
For the serial port cable, ground the shield in both ends of the cable and also put
ferrite cores in both ends. However, in the case of cabinet side, ground the shield
near the inlet of the cable. In the case of RS232C of FANUC series 16i/18i, ferrite
cores are not needed.

(24). DC24V Power supply cable for various unit
Use conventional vinyl copper wire or cabtyre cable when the cable stays within a
cabinet or the cable goes to another cabinet through metal duct.
Use overall shield cable when the cable goes out of the cabinet without metal duct
and ground the shield in both ends. The various units are
I/O unit, Additional I/O of Series 0, Power supply unit for Series 20/21
Connection unit for operator’s panel
Standard machine operator’s panel with I/O link, etc.
(25). Communication cable for I/0 unit Model B
For the communication cable for I/0 unit Model B, use overall shield cable and
ground the shield in both ends. For the communication cable, there is a special
cable to be used. See Connection Manual of I/O unit model B.
(26). Battery cables
Use overall shield cable and ground the shield in NC side.
(27). Connection cables to electric devices put in machine side
Cables that from a relay panel in a cabinet to electric devices (e.g. induction motor,
solenoid valve, etc.) in machine side could also are antennas. Use shield wires and
ground the shield in the cabinet.
(28). Input power cable
Use conventional cabtyre cable.
(29). AC 200V input power cable for PSM control
Use conventional cabtyre cable. But put ferrite core in PSM side like below.
