10 OPTICAL ADAPTER

The signal cable K1X shown in the general connection diagram (in section 4.1) can be extended to the

maximum length of 200 m with optical fiber cables using an optical adapter for I/O Link i or optical adapter

for I/O Link.

Note that the optical adapter types differ between I/O Link i and I/O Link.

NOTE

1 For the cable K2X, the optical adapter for I/O Link i or optical adapter for I/O Link.

cannot be applied to.

2 In the following cases, make sure to use an optical fiber cable for K1X. For cabling

within the same cabinet, however, this applies only when the cable is 15 m or

longer.

• When the cable is more than 10 meters long.

• When the cable K1X runs between different cabinets and it is impossible to

connect the cabinets with a wire of 5.5 mm² or thicker.

• When there is concern that the cable K1X is influenced by strong noise.

For example;

When there is a strong electromagnetic noise source beside the cable K1X

such as a welding machine and the like.

When a noise generating cable such as a power cable and the like runs for a

long distance in parallel with the cable K1X.

10.8 OPTICAL FIBER CABLE

An optical fiber cable is used to connect between the optical connector of an optical adapter and that of

another optical adapter. Unlike the conventional power cables, optical fiber cables need special care in

installation and handling. No optical fiber cable can be used on movable parts.

Reinforced optical fiber code diameter: 8.4mm

Tensile strength: Optical fiber code: 25kg

Optical fiber code-connector: 2kg

Reinforcing cover: 150kg

Bending radious of optical fiber code with reinforcing cover: 50mm

(1) Standard length of an optical fiber cable is 10, 15, 20, 30, 50, 100, and 200 meters.

(2) No machine tool builder is allowed to cut or joint optical fiber cables.

(3) If it needs to relay on cabling, use optical fiber junction adapter. Up to the relay points are allowed on

a transmission line.

10.8.2 Notice of Optical Fiber Cable Handling

(1) Even though reinforcing cover used on the optical fiber code has enough mechanical strength, be sure

not to be damaged by heavy materials drop.

(2) Detaching and attaching of optical connector should always be made by touching connector. Optical

fiber code should not be touched when replacement.

(3) Optical connector is automatically locked with upper side lock levels after being connected. It is

impossible to pull out the connector without releasing the lock levers.

(4) Optical connector cannot be connected oppositely. Be sure the connector direction when connection is

done.

(5) Optical connector should be processed as follows before laying of optical fiber cable.

Fix a reinforcing cover to a wire with hook or tension member by a tape.

At laying hook the wire or pull the tension member taking enough care that optical connector does not

receive pulling strength.

(6) Reinforcing cover is fixed to cable lamp so that optical fiber cable could not weigh directly the

connecting part of connector.

(7) Notice that optical connector's chip is clear.

The attached protect cap must be always put on when optical connector is not used.

Remove dirty with a clear tissue or absorbent cotton (cotton with ethyl alcohol is applicable). No other

organic solvent than ethyl alcohol cannot be used.

10.8.3 Optical Fiber Cable Clamping Method

When reinforcing cover is fixed at cable clamp with sponge, enough sag at optical fiber code as shown

below is necessary so that connecting part of optical should not be weighed directly by optical fiber cable.

Specification: A02B-0094-K841

NOTE

1 Up to one relay points are permitted.

2 No optical fiber junction adapter can be used with the high-speed optical adapter

for I/O Link.

(3) Installing the optical fiber junction adapter

The optical fiber junction adapter should be installed within a cabinet, as a rule. If it is impossible to avoid

installing it within a cabinet, protect the adapter and the optical fiber cable portions (such as connectors and

cords) not covered with reinforcement coating from the outside air by, for example, covering them with

packing.

(4) Environmental resistance of the optical fiber junction adapter

• The optical fiber junction adapter is not waterproof. Even when optical fiber cables are attached to

both ends of the adapter, there are very small gaps in the linked portions, so water resistance cannot be

expected.

• When optical fiber cables are attached to both ends of the junction adapter installed in a normal

environment (such as within a cabinet), it is unlikely that dust will penetrate between the adapter and

optical fiber cable to the degree that it may hamper normal optical linkage. If one or both ends of the

adapter are left open, dust and dirt may accumulate even when the adapter is in a normal environment

(such as within a cabinet). The dust and dirt on the adapter ends is likely to hamper normal optical

linkage when the optical fiber cables are attached. In such a case, clean the junction adapter and the

optical connector using the optical fiber junction adapter cleaning method described below.

• Do not allow cutting fluid to splash over the adapter or those optical cable portions (such as connectors

and cords) that are not covered with reinforcement coating. If the inside of the adapter and fiber end

surfaces are contaminated with cutting fluid, a malfunction may occur.

(5) Cleaning

If the optical fiber junction adapter, optical adapter, and optical fiber cable are soiled, clean them according

to the following procedures.

• Cleaning the optical fiber junction adapter and optical adapter

First, clean the entire housing by wiping it with a cloth moistened with, or by washing it in ethyl

alcohol. Similarly, wash the two sleeves in the adapter or wipe them with a cotton swab or the like.

• Cleaning optical fiber cables

For the optical fiber cables, it is important to clean the connectors at their ends. Any soiling on the

optical fiber cable end surfaces will hamper optical transmission, resulting in a malfunction. Wipe the

optical fiber cable end surfaces (that is, the ferrule end surfaces) thoroughly with a soft, clean cloth

(like gauze) moistened with ethyl alcohol, in the same way as described above.

- 166 -

B-61813E/06

CONNECTION

10.OPTICAL ADAPTER

The use of cotton swabs may prove convenient. The fiber end surfaces of low-loss optical fiber cables

are lower than the ferrules. To remove any soiling from the fiber end surfaces completely, push the

cotton swab or gauze into the depressions all the way through while rotating the ferrule. If the ferrules

and optical connectors are contaminated with oily substances, and they may extend over a cleaned

fiber end surface when it is attached to the optical-to-electrical conversion module, it is a good idea to

wash them before wiping the optical fiber cable end surfaces, using the procedure stated above.

10.8.5 Maximum Transmission Distance by Optical Fiber Junction

Cable

Maximum transmission distance by optical fiber junction cable is shown below:

The maximum transmission distance varies depending on the number of relay points supported by optical

fiber junction adapters. When the high-speed type optical adapter for I/O Link is in use, no optical fiber

11.1 OVERVIEW

If a slave unit (such as the FS0, Power Mate, I/O Unit-MODEL A, or connection unit) is removed from the

FANUC I/O Link ^(Note), the group number for those that followed the removed slave unit changes. So, it

becomes necessary to change the PMC assignment. However, connecting a FANUC I/O Link dummy unit

in place of the removed slave unit makes it unnecessary to change PMC assignment.

This chapter describes the electrical and structural specifications that apply to the FANUC I/O Link dummy

unit when it is connected to the FANUC I/O Link.

NOTE

1 The I/O Link dummy unit is dedicated to I/O Link. It cannot be used with I/O Link i.

13.7 CONNECTING THE THREE-CHANNEL I/O Link

CONNECTOR ADAPTER TO I/O UNITS

The 3-channel I/O Link connector adapter can be connected to each I/O Unit in the same manner as for the

I/O Link i or I/O Link. However, note the following points:

Signals on channels 1 and 2 of I/O Link i and I/O Link are allocated to the JD44A-1. Signals on channel 2 of

I/O Link i and I/O Link and those on channel 3 of I/O Link are allocated to the JD44A-2.

The JD1A connector is dedicated to I/O Link channel 3.

(1) To branch out the 3-channel signals, an ordinary I/O Link cable is connected to each of the JD44A-1,

JD44A-2, and JD1A. In this case, the JD44A-1, JD44A-2, and JD1A correspond, respectively, to

channels 1, 2, and 3.

(2) To extend channels 1 and 2 together, the 2-channel I/O Link connector adapter is connected to the

JD44A-1 to separate channels 1 and 2 from each other after the adapter.

To use channel 3, connect it to the JD1A; the JD44A-2 cannot be used.

(3) To extend channels 2 and 3 together, the 2-channel I/O Link connector adapter is connected to the

JD44A-2 to separate channels 2 and 3 from each other after the adapter.

To use channel 1, connect it to the JD44A-1; the JD1A cannot be used.

14.SAFETY FOR USING AC

CONNECTION

B-61813E/06

14 SAFETY FOR USING AC

IF AC output module or AC input module is used, Section 14.1 is recommended for safety. When using it

for a machine directed to the European market, carefully observe the descriptions in Section 14.1 [as per

EN50178].

14.1 ENVIRONMENT FOR INSTALLATION

14.1.1 Installation Category (Overvoltage Category)

Install the unit in the environment of Installation Category II

(Overvoltage Category II) or better.

[EN50178]

The available impulse surge level to the ground that appears in the power source is 2.5kV maximum.

(100VAC system power source is needed in AC input module According to the standard, the available

impulse surge level to the ground is 1.5kV for this power source (voltage of which is 150VAC or less).

However, for this module, the available impulse surge level to the ground that appears in the power source

is 2.5 kV.)

Generally, an isolation transformer used for the main power source is regarded as an effective surge filter.

The class of the 16-point relay output module (AOR16G) is set to installation category (overvoltage

category) I.

(Keep any impulse voltage to ground that may appear on the AC power to within 1.5 kV.)

The class for the 8-point relay output module (AOR08G), AC output module, and AC input module is set to

installation category (overvoltage category) II.

WARNING

Connect the same phase of a power source to the commons of the AC input and

AC output modules. Otherwise, burnout or fire may occur.

NOTE

1 The AC output module incorporates a 3.2 A fuse per common. It is assumed that,

if the load is short-circuited, the fuse blows to protect the triac. However, be

sufficiently careful not to cause a short circuit because no little damage occurs to

the triac when the fuse blows.

2 If external AC input lines run through a long omnibus cable, inter-wire mutual

capacitances may cause induced current to flow from live lines to open lines,

leading to an ON state. If this is the case, a typical measure might be to lower the

input impedance by attaching a bleeder resistance between the input pins.

3 If a reed switch is used as the input contact of the AC input module, the reed

switch must be one having a permissible current capacity of 1 A or higher.

Otherwise rush current may cause the contact to be welded.

14.1.2 Pollution Degree

Install the unit in the environment of pollution degree 2 or better. [EN50178]

In cabinet of IP-54 or better (described in Section 3.1), it can be considered as pollution degree 2 or better

usually. The IP degree required is depended on the circumstances of machine tool, so select the adequate

degree in accordance with such environment.
