ALLOCATION OF I/O POINTS

I/O Link i and I/O Link each have the following number of I/O points per channel or group as viewed from

the master.

slaves.

Each slave can occupy as many I/O points as determined for it. For the I/O Link i or I/O Link, the total

number of I/O points occupied by all slaves per channel must meet:

Number of input points ≤ Xc

Number of output points ≤ Yc

Number of actual I/O points may differ from that of the occupied ones.

How to determine the number of I/O points to be allotted to each slave and restrictions for allocation are

shown in the followings.

(For the allocation method for I/O points, refer to the PMC PROGRAMMING MANUAL.)

(1) Sum the numbers of the I/O points for all slaves connected with a single I/O Link i or I/O Link. The

sum must satisfy the following restriction :

Number of input points ≤ Xc (per one channel)

Number of output points ≤ Yc (per one channel)

(2) Number of the occupied I/O points per one group must satisfy the following restriction :

Number of input points ≤ Xg (per one group)

Number of output points ≤ Yg (per one group)

(3) Determine the number of I/O points for the I/O Unit-A using the following.

[Output points]

Sum of the actual output points in a group

Occupied output points

0 to 32

⇒ 32 points

40 to 64

⇒ 64 points

72 to 128

⇒ 128 points

136 to 256

⇒ 256 points

NOTE

Count AOA05E as 8 points AOA12F as 16 points.

⇒ 32 points

40 to 64

⇒ 64 points

72 to 128

⇒ 128 points

136 to 256

⇒ 256 points

However, as result of the calculation above, when the number of input points is not larger than that of

the output points in a single group, the number of input points is assumed to be equal to that of the

output points.

Example 1 :

When the following modules are used in the group No. 0.

AOD32C 3

AID32A

AOA12F 2

AIA16G

[Output points]

32 × 3 + 16 × 2 = 128 ⇒ 128 points

[Input points]

32 × 5 + 16 × 3 = 208 ⇒ 256 points

Example 2:

When the following modules are used in the group No.2

AOD16C 7 AID16C 4

AOA05E 9 AIA16G 3

[Output points]

16 ×7 + 8 ×9 = 184 ⇒ 256 points

[Input points]

16 ×4 + 16×3 = 112 ⇒ 128 points

In this case, as the number of input points is not larger than that of the output points, the number of

input points is assumed to be equal to that of the output points, in other words, 256 points.

NOTE

If no base expansion has been performed, an attempt to allocate I/O points for

base expansion results in an I/O Link error.

ENVIRONMENT FOR INSTALLATION

3.1.1

Environmental Conditions inside the Cabinet

The peripheral units and the CNC unit have been designed on the assumption that they are housed in closed

cabinets. In this manual "cabinet" refers to the following:

• Cabinet manufactured by the machine tool builder for housing the CNC unit or peripheral units;

• Operation pendant, manufactured by the machine tool builder, for housing the LCD/MDI unit or

operator's panel.

• Equivalent to the above.

The environmental conditions when installing these cabinets shall conform to the following table. Section

3.2 describes the installation and design conditions of a cabinet satisfying these conditions.

NOTE

If the CNC is installed 1000 m or higher above sea level, the allowable upper

ambient temperature of the CNC in the cabinet is changed as follows.

Assume that the allowable upper ambient temperature of the CNC in the cabinet

installed 1000 m or higher above sea level decreases by 1.0°C for every 100 m

rise in altitude.

Example)

The upper allowable ambient temperature of the CNC in the cabinet installed

1750 m above sea level is:

55°C - (1750-1000)/100 × 1.0°C = 47.5°C

Therefore, the allowable ambient temperature range is from 0°C to 47.5°C.

DESIGNING CONDITION FOR A CABINET

When designing a cabinet to contain the I/O Unit-A, take the same care as taken for the cabinet containing

the CNC control unit and other units. For details, refer to the CNC CONNECTION MANUAL.

In addition, when mounting the I/O Unit, conform to the followings in view of maintenance, environmental

durability, noise resistance and the like.

(1) In order to ventilate inside the module well, mount the I/O Unit in the direction shown in the figure

below.

Upside

Downside

(2) Separate each I/O Unit at least 100 mm vertically from the other units so as to ensure effective

ventilation and make it easy to attach/detach wires and modules.

(3) Do not put equipments which generate a large amount of heat under the I/O Unit.

(4) Low-level signals are transferred through the signal cables K1X and K2X. (For these cables, see the

general connection diagram.) Lay out these cables apart from the wires for AC power source and the

I/O wires of the I/O module by 100 mm or more.

(5) Make sure that there is no protruding portion such as a screw on the mounting surface of the I/O Unit.

(6) See Section 3.4, “HEAT VALUE AND WEIGHT OF EACH MODULE” for heat values of I/O Unit.

MOUNTING AND DISMOUNTING MODULES

Interface modules and various types of I/O modules can be mounted to and dismounted from the base unit

easily as shown below.

Mounting

Hang the hook at the top of the module on the groove in the upper side of the base unit, and make the

connector of the module engage with that of the base unit. Push the module in the lower groove of the

base unit till the stopper in the lower side of the module stops.

Dismounting

Release the stopper by pushing the lever at the bottom of the module, and then push the module

upwards.

4.CONNECTION

NOTE

1 Number of I/O Units and connecting method are restricted depending on the

allocation of the I/O points. Refer to the section 1.3,"Allocation of I/O points."

2 In case of communication method is I/O Link, one group consists of up to two I/O

units. If the master unit is the F-D Mate, however, one group consists of up to four

I/O units. If the master unit is the F-D Mate, one group can consist of up to four I/O

Units.

3 In case of communication method is I/O Link i, one group consists of up to one I/O

unit only. (No base expansion is allowed.)

4 Cable K1X can be an optical fiber cable by using the optical I/O Link adapter.

See chapter 10.

5 Terminator TX is required for connector JD2 of the AIF01B that is the last unit to

be connected in the group. If no AIF01B is in use, no terminator has to be attached

to the JD2 connector of the AIF01A or AIF01A2.

6 If you want to have the I/O Unit-A support I/O Link i, use the interface module

AIF01D. Doing so makes it possible to the use existing base units and DI/DO

modules.

However, the high-speed counter modules whose unit drawing number is

A03B-0819-C053 or A03B-0807-C053 are dedicated to I/O Link. (See Chapter 8.)

7 Usable power connectors vary depending on which interface module is used.

Before using interface modules, be sure to check their power connectors.

NOTE

1 Turn ON the power for the I/O Unit just when or before the power for the CNC or

the cell controller is turned ON. When the CNC or cell controller power is turned

OFF, make sure to turn the power to the I/O Unit OFF as well. Failing to observe

this power ON/OFF sequence may result in an error occurring in the CNC unit or

an I/O unit not being recognized normally.

2 For system safety, configure an external circuit so that the load is supplied with

power only after the I/O unit is supplied with power. Supplying power to the load

before the I/O unit may lead to an accident due to an incorrect output or

malfunction of an output module or the like when the I/O unit is turned on.

3 Always shut off the power to the load before the I/O unit. Otherwise, it is likely that

a machine breakdown or accident may occur.

4.CONNECTION

NOTE

1 Connect the screw terminal for grounding terminal to the grounding hole portion.

2 Use dedicated grounds as much as possible.

Observe your national grounding standards (protective grounding class C or

stricter). If possible, use a dedicated ground to isolate it from that for other units.

If no dedicated ground is available for the unit, it can share a common ground with

other units.

However, absolutely avoid having the unit share a ground with high-power

equipment such as motors and inverters. Ground them at their respective

grounds so that they will not mutually affect others.

Do not ground the unit at a point where many units are grounded in order to

prevent electrical shocks.

3 Use single-point grounding so that no noise will be induced on the grounding

line between units. In some cases, however, both ends grounding or both ends

opening may be more effective depending on the environment where the unit is

used. Select one of the grounding types, whichever is appropriate, depending on

what the ambient noise is like.

In this way, using the AIF02C eliminates the necessity for the interface unit (BIF04A1) for I/O Unit-B,

which has conventionally been used separately; this configuration is suitable for a small I/O Unit-B system.

Note the following points.

NOTE

1 The AIF02C is dedicated to I/O Link. It cannot be used with I/O Link i.

2 The AIF02C cannot be used for base expansion.

3 The BIF04A1 can branch to a maximum of eight communication lines.

The AIF02C can branch only to a maximum of two distributed link cables.

(2) Connection with the I/O Link

The AIF02C occupies two groups on the I/O Link.

When groups #n and #n+1 are used, for example, the smaller-numbered group, #n, is assigned to the

I/O Unit-A, and the larger-numbered group, #n+1, is assigned to the I/O Unit-B.

[a] Connection of the I/O Link cable

Connect the I/O Link cable from the previous group to JD1B. Connect JD1A to the I/O Link

cable leading to the next group. Use the K1X I/O Link signal cable, the same I/O Link signal

cable type as that for the AIF01A.

[b] Number of occupied I/O points on the I/O Link

The nominal number of occupied I/O points may differ from the actual number of I/O points.

For the details of the number of I/O points occupied by the I/O Unit-B, refer to Section, "Number of

points occupied on the interface unit I/O Link," of the FANUC I/O Unit-B MODEL Connection

Manual (B-62163E).

(1) EDSP (error display method selection)

Normally, set EDSP to the ON position.

(2) Q and H (communication speed setting)

Normally, set both Q and H to the OFF positions.

(3) URDY (setting of the power on/off information for the unit)

Normally, set URDY to the OFF position.

(4) R (terminating resistor setting)

The ON position means that a terminating resistor must be installed. The OFF position means that no

terminating resistor need be installed.

When only one communication cable is connected to the AIF02C, terminate it and the basic unit at the

end of the communication cable with a resistor.

When two communication cables are connected to the AIF02C, terminate the basic unit connected to

the end of each communication cable with a resistor. Do not connect a terminating resistor to the

AIF02C. (Refer to Subsection 4.6.2, "Connection.")

WARNING

1 If the load current of a module with no built-in fuse exceeds its rating continuously

for a long time, it is likely that smoke or ignition may occur. In order to prevent

burnout, it is recommended to use a fuse rated twice the output rating at every

external terminal.

2 Some modules have a built-in fuse for each common. However, no such output

module can be protected from overload. Be sure to use them within their rating. In

order to protect modules from overload, it is recommended to attach an external

fuse to each of them.

3 It is likely that, if a short circuit occurs, an external fuse (even if provided) for an

output module may fail to protect its components. If an external load is

short-circuited, ask for repair.

4 As for modules having an output protection element, the protection function is

intended to protect the components internal to the modules rather than external

units.

5 No protection function of modules can protect their internal components in all

cases. Once any protection function has worked, remove the cause promptly. If an

absolute maximum rating is exceeded, for example, it is likely that protection

functions may not work or an IC may break down before the related protection

function works, depending on the way or situation in which the modules are used.

6 If an output protection function is defective, it is likely that, if the load current

exceeds its rating continuously for a long time, smoke or ignition may occur.
