Introduction

This manual describes the various signal interfaces and functions required when creating sequence program of PLC CPU to operate C70.Read this manual thoroughly before programming. Thoroughly study the "Safety Precautions" on the following page to ensure safe use of this CNC unit.

Details described in this manual

For items described in "Restrictions" or "Usable State", the instruction manual issued by the machine maker 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 option functions are added. Refer to the specifications issued by the machine maker before starting use.Some screens and functions may differ or may not be usable depending on the CNC version.

CAUTION

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.

There are no "Danger" items in this manual.

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

handling is mistaken.

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

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 indicated a thing that is pompously (must do).

For example, indicates "it must be grounded".

DANGER

1. Items related to prevention of electric shocks

Do not operate the switches with wet hands, as this may lead to electric shocks.

Do not damage, apply excessive stress, place heavy things on or sandwich the cables, as this may lead to electric shocks.

1. Items related to product and manual

For the items described in the "Restrictions" and "Usable State", the instruction manual issued by the machine maker takes precedence over this instruction manual.

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

This manual has been written on the assumption that all options are provided.Check the specifications issued by the machine maker before starting use.

Some screens and functions may differ or may not be usable depending on the CNC system version.

2. Items related to connection

When using an inductive load such as relays, always contact a diode in parallel to the load as a noise measure.

When using a capacitive load such as a lamp, always connect a protective resistor serially to the load to suppress rush currents.

3. Items related to design

Always turn the spindle phase synchronization completion signal ON before chucking both ends of the workpiece to the basic spindle and synchronous spindle. If the spindle phase synchronization signal is turned ON when both ends of the workpiece are chucked to the basic spindle and synchronous spindle, the chuck or workpiece could be damaged by the torsion that occurs during phase alignment.

If the temperature rise detection function is invalidated with the parameters, the control could be disabled when the temperature is excessive. This could result in machine damage or personal injuries due to runaway axis, and could damage the device. Enable the detection function for normal use.

In order to prevent illegal transfer of bit data, use data update program.

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!
