MITSUBISHI CNC 700 Series ALARM/PARAMETER MANUAL

IB(NA)1500038(ENG)＊

MITSUBISHI CNC is a registered trademark of Mitsubishi Electric Corporation. Other company and product names that appear in this manual are trademarks or registered trademarks of the respective company.

PREFACE

This manual is the alarm/parameter guide required to use the MITSUBISHI 700 Series. This manual is prepared on the assumption that your machine is provided with all of the 700 Series functions. Confirm the functions available for your NC before proceeding to operation by referring to the specification issued by the machine manufacturer.

Notes on Reading This Manual

(1) This manual explains general parameters as viewed from the NC.

For information about each machine tool, refer to manuals issued from the machine manufacturer. If the descriptions relating to “restrictions” and “allowable conditions” conflict between this manual and the machine manufacturer's instruction manual, the later has priority over the former.

(2) This manual is intended to contain as much descriptions as possible even about special operations.

The operations to which no reference is made in this manual should be considered impossible.

(3) The “special display unit” explained in this manual is the display unit incorporated by the machine

manufacturer, and is not the MITSUBISHI standard display unit.

Caution

If the descriptions relating to the “restrictions” and “allowable conditions” conflict between this manual and the machine manufacturer’s instruction manual‚ the latter has priority over the former.

The operations to which no reference is made in this manual should be considered impossible.

This manual is complied on the assumption that your machine is provided with all optional functions. Confirm the functions available for your machine before proceeding to operation by referring to the specification issued by the machine manufacturer.

In some NC system versions‚ there may be cases that different pictures appear on the screen‚ the machine operates in a different way or some function is not activated.

Precautions for Safety

Always read the specifications issued by the machine maker, 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".

CAUTION

Note that even items ranked as "

important information that must always be observed is described.

Not applicable in this manual.

1. Items related to product and manual

If the descriptions relating to the “restrictions” and “allowable conditions” conflict between this

manual and the machine manufacturer’s instruction manual‚ the latter has priority over the former.

The operations to which no reference is made in this manual should be considered impossible.

This manual is complied on the assumption that your machine is provided with all optional

functions. Confirm the functions available for your machine before proceeding to operation by referring to the specification issued by the machine manufacturer.

In some NC system versions‚ there may be cases that different pictures appear on the screen‚

the machine operates in a different way on some function is not activated.

2. Items related to faults and abnormalities

If the BATTERY LOW alarm is output, save the machining programs, tool data and parameters

to an input/output device, and then replace the battery. If the BATTERY alarm occurs, the machining programs, tool data and parameters may be damaged. After replacing the battery, reload each data item.

WARNING

CAUTION

[Continued on next page]

CAUTION

3. Items related to maintenance

Do not replace the battery while the power is ON.

Do not short-circuit, charge, heat, incinerate or disassemble the battery.

Dispose of the spent battery according to local laws.

4. Items related to servo parameters and spindle parameters

With the MDS-C1 Series, only the serial encoder is compatible as the motor end detector. The

OHE/OHA type detector cannot be used as the motor end detector.

Do not adjust or change the parameter settings greatly as operation could become unstable.

In the explanation on bits, set all bits not used, including blank bits, to “0”.

When orientation was completed, the error between the command and feedback exceeded the value set in the parameters. If the number of orientation retry times parameter SP118 is set, “S52 SERVO WARNING 00A9” will occur, and then this alarm will occur. (An alarm will occur if the error exceeds SP114: OPER. This cannot be detected when using magnetic sensor orientation, so set SP114 to 0.)
