SAFETY PRECAUTIONS

2 GENERAL WARNINGS AND NOTES

WARNING

1Before operating the machine, thoroughly check the entered data.

Operating the machine with incorrect data may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user.

2Never attempt to perform a production run, such as actually machining a workpiece, without first checking the operation of the machine. Before starting the machine for a production run, ensure that the program command values, offsets, current position, external signals, and other settings are suitable for the operation to be performed. Also check that the machine operates correctly by performing a trial run using, for example, the single block, feedrate override, or machine lock function or by operating the machine with neither a tool nor workpiece mounted.

3Ensure that the specified feedrate is appropriate for the intended operation. Generally, for each machine, there is a maximum allowable feedrate.

The appropriate feedrate varies with the intended operation. Refer to the manual provided with the machine to determine the maximum allowable feedrate.

If a machine is run at other than the correct speed, it may behave unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user.

4When using a tool compensation function, thoroughly check the direction and amount of compensation.

Operating the machine with incorrectly specified data may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user.

SAFETY PRECAUTIONS

B-62714EN/04

WARNING

5The parameters for the CNC and PMC are factoryset. Usually, there is not need to change them. When, however, there is not alternative other than to change a parameter, ensure that you fully understand the function of the parameter before making any change.

Failure to set a parameter correctly may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user.

6Immediately after switching on the power, do not touch any of the keys on the MDI panel until the position display or alarm screen appears on the

CNC unit.

Some of the keys on the MDI panel are dedicated to maintenance or other special operations. Pressing any of these keys may place the CNC unit in other than its normal state. Starting the machine in this state may cause it to behave unexpectedly.

7The operator's manual and programming manual supplied with a CNC unit provide an overall description of the machine's functions, including any optional functions. Note that the optional functions will vary from one machine model to another. Therefore, some functions described in the manuals may not actually be available for a particular model.

Check the specification of the machine if in doubt.

8Some functions may have been implemented at the request of the machine-tool builder. When using such functions, refer to the manual supplied by the machine-tool builder for details of their use and any related cautions. Refer to the following two examples.

<1> Some machines have a tool replacement device that operates when a tool feature is executed. When the user is working near the device, he or she may touch it. Execute tool features in a place sufficiently away from the tool replacement device.

<2> Many auxiliary features cause machine operation such as rotation of the spindle. Understand the operations of auxiliary features before using them.

B-62714EN/04

SAFETY PRECAUTIONS

NOTE

Command programs, parameters, and variables are stored in nonvolatile memory in the CNC unit. Usually, they are retained even if the power is turned off. Such data may be delated inadvertently, however, or it may prove necessary to delete all data from nonvolatile memory as part of error recovery. To guard against the occurrence of the above, and assure quick restoration of deleted data, backup all vital data, and keep the backup copy in a safe place.

1.3 SLAVE FUNCTION

The slave function consists of the following functions:

(1)DI/DO data transfer function

(2)Global I/O transfer function (FANUC unique function)

(3)Capability of turning on and off the power to a slave station at any time without affecting communications performed by other devices

NOTE

FANUC I/O Link-II (slave function) uses the following services of OPCN-1:

(1)Initialization service

(2)Input/output service

(3)Reset service

About the global I/O transfer function:

The figure below shows DI/DO data transfer performed between a master station and slave stations #1 to #N. Suppose that a slave station using the global I/O transfer function is a local slave station, and the other slave stations are remote slave stations. Then, the local slave station (#2) can receive DO data sent from the master station and can also receive DO data sent to the master station from the remote slave stations. So, the local slave station can make a ladder reference.

DO data from slave stations #1 to #N (excluding #2)

NOTE

The global I/O transfer function is not a function defined by OPCN-1 but a FANUC unique function. This function can be used even when the network includes products of other manufacturers (even as a master station). In this case, however, the size of data that can be transferred is limited.

1.5 GLOSSARY

Key terms used this manual are explained below.

OPCN-1 (formerly called JPCN-1 or JEMA net)

Field network defined by the Japan Electrical Manufacturer's Association

OPCN-1 certified device

FANUC device that passed the OPCN-1 certification test Certification number: J990705JPCNM026

Date of certification: July 5, 1999

Master station

Station that establishes and cancels logical communication paths to multiple slave stations, manages the data transmission service issue sequence and error recovery sequence, and performs I/O transfer. One OPCN-1 network can include only one master station.

Slave station

Station that exercises communication control and performs I/O transfer to and from the master station according to instructions from the master station. One OPCN-1 network can include up to 31 slave stations.

Initialization service

Service defined by OPCN-1 for information exchange and setting to establish logical communication paths between the master station and slave stations. When the initialization service is executed successfully, input/output service can be started.

Input/output service

Service defined by OPCN-1 for DI/DO data transfer between the master station and slave stations

Reset service

Service defined by OPCN-1 for the master station to reset slave stations to the initial state

Initial state

State where no logical communication path is established

Detachment

State where communication (input/output service being performed) with the remote station is disabled

Disconnection

State where communication is not performed (such as in the initial state or detached state)

1.I/O LINK-II I/O FUNCTION

DI data

Input data when viewed from the local station (master station or slave station)(Caution)

DO data

Output data when viewed from the local station (master station or slave station)(Caution)

CAUTION

In the OPCN-1 specifications, data input/output is defined as data input/output viewed from the master station. Note that the use of the term in this manual for slave stations is opposite to the definition in the OPCN-1 specifications.

For communication with devices of other manufacturers, check the definition of data input/output.

DI/DO data transfer function

Function for exchanging DI/DO data between the master station and slave stations of I/O Link-II. This function is implemented by input/output service of OPCN-1.

Global I/O transfer function

FANUC unique function. When DI/DO data is exchanged between the master station and multiple slave stations, a slave station receives DO data sent from the other slave stations to the master station, thus achieving I/O transfer between the slave stations.

Successive error detach detection counter

Maximum allowable number of successive communication errors. When this maximum number is exceeded, a detachment is detected.

One scan

Executing input/output service once for all slave stations connected to the network

Slave type

Initialization service parameter defined by OPCN-1 for determining the type of communication between the master station and slave stations
