CONNECTION WITH INPUT/OUTPUT DEVICES

5.2.1

Overview

An input/output device is used to enter information such as CNC programs and parameters from an

external device to the CNC, or to output information from the CNC to an external device.

The interface of the input/output devices electrically conforms to RS-232-C, so that a connection can be

made with a device that has an RS-232-C interface.

The tables below indicate the serial ports of this CNC.

Note

NOTE

When using the touch panel, the interface of the second channel cannot be used

as the interface of input/output devices because it is used to communicate with

the touch panel on the CNC side.

Condition3 EIA code O is : in ISO code.

2 Control codes DC1 to DC4 are transmission codes output from the NC.

So they need not to be punched on the NC tape.

(3) Transmission rate (Baud rate)

The transmission rate (Baud rate) is the number of bits transferred per second.

The following baud rates are available depending on the system parameter.

50, 100, 110, 150, 200, 300, 600, 1200, 2400, 4800, 9600, 19200

[Example]

Baud rate : 110

When using one start bit and two stop bits (totalling 11 bits per character):

Transmission characters/second= 110/11

=10 characters/second (Max.)

(4) Cable length

The cable length depends on the external device type. Consult with the device manufacturers for

actual connecting cable lengths.

Cable length is as follows by the specification of NC.

5.4

LINKING THE EMBEDDED ETHERNET INTERFACE

CAUTION

Before attaching or removing cables, power off the CNC main unit, and confirm

that the power is off.

Ask the respective manufacturers for explanations about how to build a network

and about conditions for using units (such as a media converter, hub,

transceiver, and cable) other than the CNC unit. When installing network

cables, exercise sufficient caution so that the network will not be affected by any

noise source. Electrically separate the network wiring sufficiently from noise

sources like motors and their power lines. Also, ground each unit as required.

If the grounding impedance is high, it may cause trouble in communication.

Once the equipment is installed, conduct communication tests to verify normal

operation before starting actual use of the equipment.

FANUC is not liable to any damage related to trouble arising from any unit other

than the CNC unit.

5.4.1

Connection to the Ethernet Interface

The 100BASE-TX interface are available. A hub (line concentrator) is used to connect the CNC unit to

a system. A typical connection example is shown below.

NOTE

1 To make a connection to the 10BASE-T Ethernet, use a hub that meets the

following conditions.

• Compliant with 100BASE-TX

• With the auto-negotiation function

• Support for the store & forward system

2 Some of the units (hub, transceiver, etc.) required to build a network are not

dust-proof/water-proof (oil-proof). Using them in an atmosphere with dust or oil

mist may lead to a communication error or failure. They should be enclosed in a

dust-proof/water-proof (oil-proof) cabinet.

Leading in Ethernet cables

An Ethernet cable should be fixed with a clamp or the like so that pulling it will not cause tension to be

applied to the connector (RJ-45) at the end of the cable. The clamp not only fixes the cable but also

grounds the shield of the cable.

10BASE-T or 100BASE-TX. To improve noise immunity in factory automation environments,

however, be sure to use twisted pair cables (STP cables) with a common shield in category 5.

Anti-Noise Measure

Separating signal lines

Ethernet cable wires belong to group C. See descriptions elsewhere for explanations about how to

separate them from wires in group A or B.

Cable clamp and shield processing

If any cable led into the CNC requires shielding, clamp it as shown below. The same method is used

also to shield Ethernet twisted-pair cables. The clamp shown in the figure works not only for cable

fixing but also for shield processing. Shield processing is very important to maintain the stable

operation of the system. Do not forget attach this clamp. See Subsection 3.5.1.3 "Cable Clamp and

Shield Processing," for details.

5.4.4

Network Installation

Even when the machine satisfies its grounding requirements, noise from the machine may get on

communication lines depending on the way the machine is installed and its environment, resulting in a

communication error. Separating and isolating the Ethernet backbone cable and PC from the machine

can prevent noise from getting on the communication lines.

An example of connection is shown below.

- 66 -

B-64303EN/03

5.CONNECTION TO CNC PERIPHERALS

NOTE

1 Ground the PC and backbone cable separately from the machine system.

If this is impossible because there is only one grounding point, use separate

grounding wires for the PC/backbone cable and the machine system up to the

grounding point.

The grounding resistance must not be higher than 100 Ω (class 3 grounding).

The grounding wire must not be thinner than the AC power line conductor, and

its cross-sectional area must not smaller than 5.5 mm².

2 In some cases, the aforementioned isolation/separation method based on

100BASE-TX cannot assure normal communication because of influence by

noise. In such worst environments, use optical fiber media to completely isolate

the machine from the PC.

CONNECTION TO THE TOUCH PANEL

5.5.1

Connection of the LCD Unit with a Touch Panel

When the LCD unit with a touch panel is used, RS232C serial port 2CH (JD36B) cannot be used as a

general-purpose port because it is used for touch panel communication. Since the touch panel

communication cable is routed before shipment from FANUC, the tool builder does not need to route it.

External Touch Panel Interface

The external touch panel interface function can be used to connect to the external touch panel that

supports the SNP-X protocol. In this case, RS232C serial port 2CH (JD36B) is used to connect between

the CNC and the external touch panel.

(1) To use one serial spindle, make a direct connection from JA41 on CNC to the spindle amplifier. And,

to two serial spindles, make a direct connection from JA7A on the first amplifier to the second

spindle amplifier.

(2) To use third serial spindle, make a connection from JA41 on CNC to the serial spindle connector

panel for a branch. And, make a connection from JA7A-1 on the serial spindle connector panel for a

branch to the first spindle amplifier, make a connection from JA7A-2 on the serial spindle connector

panel for a branch to the third spindle amplifier

(3) To use the position coder for an analog spindle, make a direct connection from JA41 to the position

coder.

NOTE

When using the serial spindle interface, the position coder interface for analog

spindles cannot be used.

6.1

SERIAL SPINDLE

6.1.1

Connection of One to Two Serial Spindles

When connecting one serial spindle amplifier, connect it to JA41. When connecting a second serial

spindle amplifier, connect it to JA7A of the first serial spindle amplifier.

Electric cables are usually used to connect serial spindles, but optical fiber cables and optical adapters

need to be used when:

The cable length is 20 m or more.

A ground wire with a cross-sectional area of 5.5 mm2 or more cannot be used to connect between

the power magnetics cabinet having spindle amplifiers installed and the operator's panel cabinet

having the CNC control unit installed.

Cables may be significantly affected by noise. For example, when there is a strong electromagnetic

noise generator such as a welding machine near the cables or when the cables runs long in parallel

with a power line that generates noise or a power magnetic cable

NOTE

The conventional optical I/O Link adapter (A13B-0154-B001) cannot be used.

Use optical adapter (A13B-0154-B003).

Conditions for installing the serial spindle connector panel

• The serial spindle connector panel does not have an enclosed structure. So, install the serial spindle

connector panel in an enclosed cabinet as used for the CNC.

• Ground the case by using the case mounting screws of the serial spindle connector panel.

• The serial spindle connector panel is light, so that it need not be secured with screws. However,

ensure that the serial spindle connector panel does not contact other electrical circuits and thus cause

a short circuit. When securing the serial spindle connector panel to the cabinet, for example, attach

an L-shaped metal fitting as shown below with a case mounting screw (M3) of the serial spindle

connector panel.
