9.2.11 Analog Input Connector Pin Allocation

This section describes the analog input connector pin allocation of expansion module D.

NOTE

1 The DI/DO addresses of an expansion module and the DI/DO addresses of the

basic module are contiguous.

Addresses allocated to I/O Link are handled as a group covering the basic and

expansion modules. That is, when the first addresses allocated are X0004 and

Y0000 (m = 4, n = 0), the DI/DO addresses are as listed below.

2 With the analog input module, the DO space is also used as an input channel

selection area.

9.2.15 Manual Pulse Generator Connection

An example in which three manual pulse generators are connected to expansion module A is shown

below.

Recommended wire material:

A66L-0001-0286 (#20AWG×6+#24AWG×3 pairs)

Recommended connector:

A02B-0120-K303 (including the following connector and case)

(Connector: Hirose Electric Co., Ltd. FI40-2015S, soldering type)

(Case: Hirose Electric Co., Ltd. FI40-20-CV5)

Recommended cables:

A02B-0120-K841 (7m) (for connecting three manual pulse generators)

A02B-0120-K848 (7m) (for connecting two manual pulse generators)

A02B-0120-K847 (7m) (for connecting one manual pulse generator)

(These cables do not include the wire shown in the above figure.)

NOTE

The number of connectable manual pulse generators depends on the type and

option configuration.

- 141 -

9.CONNECTION OF I/O Link SLAVE DEVICES

B-64303EN/03

9.2.16 Cable Length for Manual Pulse Generator

Like a pulse coder, the manual pulse generator operates on 5 VDC. The supply voltage drop due to the

cable resistance must be held below 0.2 V (when those of the 0-volt and 5-volt wires are combined), as

expressed in the following expression:

0.1×R×2L

Where 0.1 : Manual pulse generator supply current [0.1 A]

0.2≥

R : Resistance per unit cable length [μ/m]

m : Number of 0-volt and 5-volt wires

: Cable length [m].

L≤

Therefore, the cable length can be determined using the following expression.

In the case of the A66L-0001-0286 cable, for example, when three pairs of signal wires and six power

supply wires (20/0.18, 0.0394 Ω/m) are used (three power supply wires connected to 5 V and the other

three to 0 V), the cable length is:

L≤

=76.75[m]

0.0394

However, the maximum pulse transmission distance for the manual pulse generator is 50 m. Taking this

into consideration, the cable length may be extended to:

38.37 m (when two generators are used), or

25.58 m (when three generators are used).

9.2.17 Connection of Basic and Expansion Modules

Modules can be connected in the same way, regardless of whether you are connecting the basic module to

an expansion module or connecting two expansion modules. Connect the modules by using 34-pin flat

cable connectors as shown in the figure below. Ensure that all 34 pins at one end of the cable are

connected to the corresponding pins at the other end;

e.g., connect the A1 pin to the pin having the same designation (A1) at the other end.

- 142 -

B-64303EN/03

9.CONNECTION OF I/O Link SLAVE DEVICES

NOTE

Modules need to be spaced at least 32 mm apart, in which case a flat cable of

about 20 mm in length is required. To install modules further away from each

other, the cable length will be 20 mm plus the extra distance. Note that the

maximum length of a flat cable is 300 mm. To ensure adequate ventilation,

install the modules in such a way that the flat cables lie on top of them. The

basic module has a vent at the top (as indicated by the dotted lines in the above

figure). When connecting modules, install expansion modules so that the flat

cables do not cover the vent, as shown in the above figure.

Therefore, for direct connection to the connection printed circuit board,

expansion modules are installed to the right of the basic module on the

installation plane. For installation using DIN rails or screws, expansion modules

are installed to the left of the basic module on the installation plane.

9.2.19 Other Notes

DO signal reaction to a system alarm

There is a possibility that the I/O module will not operate normally due to a failure of CNC or I/O Link

slave module, or abnormally power supply voltage. To prevent accidents even in this case, design the

machine to operate safely by making a safety circuit outside the I/O module.

The circuit of this I/O module is designed so that all DO signals are turned off if a system alarm is

occurred in the CNC which controls the I/O module, or if a power of the CNC or the I/O module is turned

off. However, it cannot be guaranteed that DO signals of the I/O module will certainly be turned off.

Therefore, manage signals related to safety by making a safety circuit outside this I/O module.

detection)

The basic connector panel I/O module is allocated a group of DI addresses (16 bytes) and a group of DO

addresses (8 bytes). Up to three hardware expansion modules can be added or removed as required.

The reason for this address allocation is explained below.

The MPG interface (MPG counter) occupies a DI space from Xm+12 through Xm+14. These addresses

are fixed regardless of whether expansion module 2 or 3 is used, and Xm+12 through Xm+14 must be

allocated as a DI work area to enable the use of the MPG. Therefore, when using an MPG for the i

series CNC, allocate DI addresses in units of 16 bytes. Do not use the DI space from Xm+12 through

Xm+14 for Ladder; the CNC processes the MPG counter value directly.

DI address Xm+15 is used for detecting overcurrent and overheating alarms that occur in the IC used in

the DO driver.

[For details, see the section describing the detection of DO (output signal) alarms.]

This address is fixed regardless of whether expansion module 2 or 3 is used, and it must be allocated as a

work area before it can be used. When using this area, therefore, allocate DI addresses in units of 16

bytes.

Basically, I/O addresses can be allocated to the connector panel I/O modules freely. When allocating DI

addresses, however, consider also the addresses that are directly supervised by the CNC, and keep the

following in mind.

(DO alarm detection)

DO (output signal) alarm detection

The DO driver of the Basic and Expansion module A/B is capable of detecting an overcurrent and

measuring its own temperature. If an accident, such as the connecting of the cable to ground, causes an

abnormal increase in the load current or in the driver temperature, a protection circuit, which is provided

for each DO driver (1 byte), is activated and keeps the DO signal for the relevant 1 byte in the OFF state

until the cause of the problem is eliminated. Even if this occurs, the CNC and I/O module continue

operating. The DI address (Xm+15) identifies the DO driver which has detected the alarm. The table

below shows the correspondence between the DI address (Xm+15) bits and the DO addresses. Bit value

"1" indicates that the corresponding DO driver has detected an alarm. The contents of the Xm+15 area

can be checked by using the DGN screen of the CNC or by performing alarm processing for the area in

advance by using Ladder. This helps alarm detection and recovery.

Allocation of the 2A output module and analog input module

The 2A output module and analog input module can be allocated to any of the spaces for expansion

modules 1, 2, and 3. When an MPG interface is required, the module occupies the space for expansion

module 1; no 2A output module or analog input module can be allocated in the space for expansion

module 1.

The 2A output module does not involve DI points, so that the DI area of the space in which a 2A output

module is allocated is unusable. When a 2A output module is allocated to the space for expansion

module 2, for example, the areas from Xm+6 to Xm+8 cannot be used.

(The spaces for the other

modules are not shifted. In this case, the DI space of expansion module 3 remains at Xm+9 through

Xm+11.)

NOTE

1 Xm+1.0 through Xm+1.7 are DI pins for which a common voltage can be

selected. That is, by connecting the COM1 CE54(A02) pin to the +24 V power

supply, a DI signal can be input with its logical state reversed. If, however, a

cable is connected to ground, it has the same effect as inputting an ON state DI

signal. To prevent this from occurring, the connection of the COM1 CE54(A02)

pin to the 0 V power supply is recommended whereever possible.

For safety reasons, the emergency stop signal needs to be allocated to an

appropriate bit of the addresses for which the common voltage is fixed, ranging

from Xm+0.0 to Xm+0.7. See "Address allocation" in Section 8.5.10 for details

of how to allocate the emergency stop signal.

For unused DI pins allocated to the addresses for which the common voltage is

fixed (from Xm+0.0 to Xm+0.7), the logic is fixed to "0". For unused pins

allocated to Xm+1.0 to Xm+1.7 for which the common voltage can be selected,

the logic is fixed to "0" when the COM1 CE54(A02) pin is connected to the 0 V

power supply. When the COM1 CE54(A02) pin is connected to the +24 V

power supply, the logic is fixed to "1". The logic of the unused pins allocated to

Xm+1.0 to Xm+1.7 is variable when the contact of the COM1 CE54(A02) pin is

open.

2 An output DC voltage of +24 V at CE53 (B02) and CE54 (B02) is for DI signals.

Do not supply 24 VDC to these pins from the outside.

9.3.10 Other Notes

DO signal reaction to a system alarm

There is a possibility that the I/O module will not operate normally due to a failure of CNC or I/O Link

slave module, or abnormally power supply voltage. To prevent accidents even in this case, design the

machine to operate safely by making a safety circuit outside the I/O module.

The circuit of this I/O module is designed so that all DO signals are turned off if a system alarm is

occurred in the CNC which controls the I/O module, or if a power of the CNC or the I/O module is turned

off. However, it cannot be guaranteed that DO signals of the I/O module will certainly be turned off.

Therefore, manage signals related to safety by making a safety circuit outside this I/O module.

detection

The operator's panel I/O module is allocated a group of DI addresses (16 bytes) and a group of DO

addresses (8 bytes). This address allocation is explained below.

The MPG interface (MPG counter) occupies DI space from Xm+12 through Xm+14. These addresses

are fixed, and Xm+12 through Xm+14 must be allocated as a DI work area to enable the use of the MPG.

Therefore, when using an MPG for the i series CNC, allocate DI addresses in units of 16 bytes. Do not

use the DI space from Xm+12 through Xm+14 for Ladder; the CNC processes the MPG counter value

directly.

DI address Xm+15 is used for detecting overcurrent and overheating alarms that may occur in the IC used

in the DO driver.

[For details, see the section describing the detection of DO (output signal) alarms.]

This address is fixed, and must be allocated as a work area before it can be used. Therefore, when using

this area, allocate DI addresses in units of 16 bytes.

Basically, I/O addresses can be allocated to the operator's panel I/O module freely. When allocating DI

addresses, however, consider also the fixed addresses that are directly supervised by the CNC, and keep

the following in mind.
