Details described in this manual

The description concerning "Signals" in the main text refers to information transmission between a machine and PLC or between

NC and PLC.

The method for controlling the signals (ON/OFF) differs depending on the machine. Refer to the manual issued by the machine

tool builder (MTB).

Some parameters can be used by end-users and some parameters are set by the MTB according to the specifications.

End-users may not be able to set or change some of the parameters described as "... can be set with the parameter #XXXX" in

the main text. Confirm the specifications for your machine with the manual issued by the MTB.

CAUTION

For items described as "Restrictions" or "Usable State" in this manual, the instruction manual issued by the

machine tool builder (MTB) takes precedence over this manual.

Items not described in this manual must be interpreted as "not possible".

This manual is written on the assumption that all the applicable functions are included. Some of them, however,

may not be available for your NC system. Refer to the specifications issued by the machine tool builder before

use.

Refer to the Instruction Manual issued by the MTB for details regarding each machine tool.

Some screens, functions, and the number of digits may differ depending on the NC system (or its version), and

some functions may not be available. Please confirm the specifications before use.

To protect the availability, integrity and confidentiality of the NC system against cyber-attacks including unau-

thorized access, denial-of-service (Dos) (*1) attack, and computer virus from external sources via a network,

take security measures such as firewall, VPN, and anti-virus software.

(*1) Denial-of-service (Dos) refers to a type of cyber-attack that disrupts services by overloading the system or

by exploiting a vulnerability of the system.

Precautions for Safety

Always read the specifications issued by the machine tool builder, this manual, related manuals and attached documents be-

fore installation, operation, programming, maintenance or inspection to ensure correct use.

Understand this numerical controller, safety items and cautions before using the unit.

This manual ranks the safety precautions into "DANGER", "WARNING" and "CAUTION".

Note that even items ranked as " CAUTION", may lead to major results depending on the situation. In any case, important in-

formation that must always be observed is described.

The following signs indicate prohibition and compulsory.

The meaning of each pictorial sign is as follows.

Mitsubishi Electric CNC is designed and manufactured solely for applications to machine tools to be used for industrial purpos-

es.

Do not use this product in any applications other than those specified above, especially those which are substantially influential

on the public interest or which are expected to have significant influence on human lives or properties.

Not applicable in this manual.

DANGER

When the user may be subject to imminent fatalities or major injuries if handling is mistaken.

WARNING

For Safe Use

DANGER

1. Items related to operation

If the operation start position is set in a block which is in the middle of the program and the program is started, the program

before the set block is not executed. Please confirm that G and F modal and coordinate values are appropriate. If there are

coordinate system shift commands or M, S, T and B commands before the block set as the start position, carry out the

required commands using the MDI, etc. If the program is run from the set block without carrying out these operations, there

is a danger of interference with the machine or of machine operation at an unexpected speed, which may result in breakage

of tools or machine tool or may cause damage to the operators.

Under the constant surface speed control (during G96 modal), if the axis targeted for the constant surface speed control

(normally X axis for a lathe) moves toward the spindle center, the spindle rotation speed will increase and may exceed the

allowable speed of the workpiece or chuck, etc. In this case, the workpiece, etc. may jump out during machining, which

may result in breakage of tools or machine tool or may cause damage to the operators.

1. Items related to product and manual

For items described as "Restrictions" or "Usable State" in this manual, the instruction manual issued by the machine tool

builder takes precedence over this manual.

Items not described in this manual must be interpreted as "not possible".

This manual is written on the assumption that all the applicable functions are included. Some of them, however, may not

be available for your NC system.

Refer to the specifications issued by the machine tool builder before use.

Refer to the Instruction Manual issued by each machine tool builder for details on each machine tool.

Some screens and functions may differ depending on the NC system (or its version), and some functions may not be pos-

sible. Please confirm the specifications before use.

To protect the availability, integrity and confidentiality of the NC system against cyber-attacks including unauthorized ac-

cess, denial-of-service (Dos) (*1) attack, and computer virus from external sources via a network, take security measures

such as firewall, VPN, and anti-virus software.

(*1) Denial-of-service (Dos) refers to a type of cyber-attack that disrupts services by overloading the system or by exploiting

a vulnerability of the system.

Mitsubishi Electric assumes no responsibility for any problems caused to the NC system by any type of cyber-attacks in-

cluding DoS attack, unauthorized access and computer virus.

2. Items related to operation

Before starting actual machining, always carry out graphic check, dry run operation and single block operation to check the

machining program, tool offset amount, workpiece compensation amount and etc.

If the workpiece coordinate system offset amount is changed during single block stop, the new setting will be valid from the

next block.

Turn the mirror image ON and OFF at the mirror image center.

If the tool offset amount is changed during automatic operation (including during single block stop), it will be validated from

the next block or blocks onwards.

Do not make the synchronized spindle rotation command OFF with one workpiece chucked by the reference spindle and

synchronized spindle during the spindle synchronization.

Failure to observe this may cause the synchronized spindle stop, and hazardous situation.

WARNING

CAUTION

3. Items related to programming

The commands with "no value after G" will be handled as "G00".

";" "EOB" and "%" "EOR" are expressions used for explanation. The actual codes are: For ISO: "CR, LF", or "LF" and "%".

Programs created on the Edit screen are stored in the NC memory in a "CR, LF" format, but programs created with external

devices such as the FLD or RS-232C may be stored in an "LF" format.

The actual codes for EIA are: "EOB (End of Block)" and "EOR (End of Record)".

When creating the machining program, select the appropriate machining conditions, and make sure that the performance,

capacity and limits of the machine and NC are not exceeded. The examples do not consider the machining conditions.

Do not change fixed cycle programs without the prior approval of the machine tool builder.

When programming the multi-part system, take special care to the movements of the programs for other part systems.

The program including a character of any language other than the display language is not correctly displayed. Do not edit

such a program. Any part of the program other than the comment part may also be changed if edited.

CAUTION
