MELDAS 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 MELDAS60/60S Series. This manual is prepared on the assumption that your machine is provided with all of the MELDAS60/60S Series functions. Confirm the functions available for your NC before proceeding to operation by referring to the specification issued by the machine manufacturer.

* The "MELDAS60 Series" includes the M64A, M64, M65, M66 and M65V. * The "MELDAS60S Series" includes the M64AS, M64S, M65S and M66S.

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 "M64D system" explained in this manual includes the M64AS, M64S, M65S and M66S.

(4) The "special display unit" explained in this manual is the display unit incorporated by the machine

manufacturer, and is not the MELDAS standard display unit.

Caution

If the descriptions relating to the "restrictions" and "allowable conditions" conflict betw een 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".

DANGER

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

WARNING

CAUTION

Note that even items ranked as " important information that must always be observed is described.

Not applicable in this manual.

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

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

CAUTION", may lead to major results depending on the situation. In any case,

DANGER

WARNING

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.

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".

Z-AX NO CRSS

One of the axes did not pass the Z-phase during the initial reference point return after the power was turned ON.

INVALID RET (Invalid return)

When manually returning to the reference point‚ the return direction differs from the axis movement direction selected with the AXIS SELECTION key.

Alarms occurring due to incorrect operation by the operator during NC operation and those by machine trouble are displayed.

• Increase the length of the near-point dog.

• Reduce the reference point return speed.

• Move the detector one rotation or more in the opposite direction of the reference point‚ and repeat reference point return.

• As the interlock function has activated‚ release it before resuming operation.

• Check the sequence on the machine side.

• Check for broken wires in the interlock signal line.

• The servo OFF function is valid‚ so release it first.

• An axis that can be removed has been issued‚ so perform the correct operations.

• The command is issued in the same direction as the direction where manual skip turned ON‚ so perform the correct operations.

• During the manual/automatic simultaneous mode‚ the axis commanded in the automatic mode became the manual operation axis. Turn OFF the manual/ automatic valid signal for the commanded axis.

This section describes alarms occurred by the errors in the servo system such as the drive unit‚ motor and encoder, etc. The alarm message‚ alarm No. and axis name will display on the alarm message screen. The axis where the alarm occurred and the alarm No. will also display on the servo monitor screen and the spindle monitor screen respectively. If several alarms have occurred‚ up to two errors per axis will display on the servo monitor screen and the spindle monitor screen respectively.
