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

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”.

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 endusers 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!

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.
