Introduction

These specifications are the programming manual used when creating the sequence program with the PLC development

software, or Mitsubishi Electric Co.'s integrated FA software MELSOFT Series (GX Developer/GX Works2).

The PLC (Programmable Logic Controller) instructions are largely categorized into the basic instructions, function

instructions and exclusive instructions. There are many types of instructions. The instructions can be used according to

the purpose and application such as the PLC support function used when supporting the user PLCs.

Supported models are as follows:

Abbreviations in this manual are as follows:

Be sure to keep this manual always at hand.

An effort has been made to describe special handling of this machine, but items that are not described

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.

Some screens and functions may differ depending on each NC system (or version), and some functions

may not be possible. Please confirm the specifications before starting to use.

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

unauthorized 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.

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

cyber-attacks including DoS attack, unauthorized access and computer virus.

Precautions for Safety

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

before 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 information that must always be observed is described.

The following signs indicate prohibition and compulsory.

The meaning of each pictorial sign is as follows.

DANGER

When there is a great risk that the user could be subject to fatalities or serious injuries if handling is

mistaken.

WARNING

When the user could be subject to fatalities or serious injuries if handling is mistaken.

CAUTION

When the user could be subject to injuries or when physical damage could occur if handling is mistaken.

This sign indicates prohibited behavior (must not do).

For example, indicates "Keep fire away".

This sign indicates a thing that is compulsory (must do).

For example, indicates "it must be grounded".

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

purposes.

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.

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.

An effort has been made to describe special handling of this machine, but items that are not described

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 each NC system (or version), and some functions

may not be possible. Please confirm the specifications before starting to use.

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

unauthorized 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.

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

cyber-attacks including DoS attack, unauthorized access and computer virus.

2. Items related to start up and maintenance

Read this manual carefully and confirm the safety enough before executing the operation of the program

change, forced output, RUN, STOP, etc. during operation. Operation mistakes may cause damage of the

machine and accidents.

3. Items related to program development

Always observe the cautions before development to develop a program.

If the data transferred does not follow the file name rule, unexpected operations will occur.

E.g. PLC program erasure

Do not read a sequence program on which a conversion error occurred into the GX Developer/GX Works2.

The file may include unexpected contents to result an illegal operation.

When an error occurred at GX Developer/GX Works2 On-line function, the error message may not explain

exactly the state in the CNC side. Always refer to the error list.

Disposal

(Note) This symbol mark is for EU countries only.

This symbol mark is according to the directive 2006/66/EC Article 20 Information for end-users and

Annex II.

Your MITSUBISHI ELECTRIC product is designed and manufactured with high quality materials and components

which can be recycled and/or reused.

This symbol means that batteries and accumulators, at their end-of-life, should be disposed of separately from your

household waste.

If a chemical symbol is printed beneath the symbol shown above, this chemical symbol means that the battery or

accumulator contains a heavy metal at a certain concentration. This will be indicated as follows:

Hg: mercury (0,0005%), Cd: cadmium (0,002%), Pb: lead (0,004%)

In the European Union there are separate collection systems for used batteries and accumulators.

Please, dispose of batteries and accumulators correctly at your local community waste collection/recycling centre.

Please, help us to conserve the environment we live in!
