Introduction
This manual is referred to when using the MELDAS C64 Series.
This manual explains how to operate the screens of the C64 Series. Read this manual
thoroughly before using the CNC unit. To safely use this CNC unit, thoroughly study the
"Precautions for Safety" on the next page before use.
Details described in this manual
CAUTION
For items described in "Restrictions" or "Usable State", the instruction manual issued
by the machine manufacturer takes precedence over this manual.
An effort has been made to note as many special handling methods in this user's
manual. Items not described in this manual must be interpreted as "Not Possible".
This manual has been written on the assumption that all option functions are added.
Refer to the specifications issued by the machine manufacturer before starting use.
Refer to the manuals issued by the machine manufacturer for each machine tool
explanation.
Some screens and functions may differ or may not be usable depending on the NC
version.
In this NC unit, the machining programs, parameters and tool compensation data are saved in
the memory (memory elements). This NC unit's memory is backed up by lithium batteries, and
under normal conditions will last 6 years from the date of manufacture. However, data contents
could be lost under the conditions described below.
To prevent data loss, output important programs, parameters, etc., to the external memory
devices and save them.
Data in the memory can be lost under these kinds of conditions.
(1) Incorrect operation
Data can be lost if the operator inadvertently changes data while editing a program or
setting parameters.
(This is not really a data loss, but it is a loss from the standpoint that the original data is
gone.)
Data can be lost if the operator inadvertently deletes data or initializes NC unit.
(2) Battery life expires
When the battery life expires and there is not enough voltage to store the data in the
memory, data can be lost by turning the power OFF.
(3) Faults
Data can be lost when faults occur and the control unit must be replaced.

Precautions for Safety
Always read the specifications issued by the machine manufacturer, 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".
When the user may be subject to imminent fatalities or major
injuries if handling is mistaken.
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.
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.
DANGER
Not applicable in this manual.
WARNING
Do not put any startup switch for C6/C64 on GOT’s touch key. If a communication fault (including
cable disconnection) occurs between GOT and CNC C6/C64, the communication will be suspended
and the GOT will become inoperative. In this case, even when you release your hands from the
startup switch, CNC will fail to recognize the cutoff of startup signal, which may cause serious
accidents.
CAUTION
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 manufacturer 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 option functions are added. Refer to
the specifications issued by the machine manufacturer before starting use.
Refer to the manuals issued by the machine manufacturer for each machine tool
explanation.
Some screens and functions may differ or may not be usable depending on the NC
version.
2. Items related to installation and assembly
Always ground the signal cable to ensure stable operation of the system. Ground the NC unit,
power distribution panel and machine to a one-point ground to establish the same potential.

CAUTION
3. Items related to preparations before use.
Always set the stored stroke limit. Setting no limits could result in collision with the
machine end.
Always turn the power OFF before connecting/disconnecting the input/output device
cables. The NC and input/output device could be damaged if the cable is connected
in the power ON state.
4. Items related to screen operation
If the tool compensation amount is changed during automatic operation (including
single block stop), the amount will be validated from the next block or several blocks
following.
If the workpiece coordinate offset amount is changed during single block stop, the
changes will be valid from the next block.
Pay close attention to the sequence operation when carrying out forced data setting
(forced output) in the PLC I/F (diagnosis) screen.
If the operation start position is set from a block in the program and the program is
started, the program before the set block is not executed. If there are coordinate
system shift commands or M, S, T, and B commands before the block set as the
starting position, carry out the required commands using the MDI, etc. There is a
danger of interference with the machine if the operation is started from the set starting
position block without carrying out these operations.
To prevent the influence of data loss and data transformation over the line, always
carry out data comparison after transferring a machining program.
Do not change the setup parameters without prior consent from the machine
manufacturer.
5. Items related to programming
If there is no value after the G command, the operation will be the "G00" operation
when the program is run due to key chattering, etc., during editing.
" ; " "EOB" and " % " "EOR" are symbols used for explanation.
The actual codes are: For ISO: "CR, LF", or "LF" and "%".
Programs created on the Edit screen are stored in the NC memory in a "CR, LF"
format, but programs created with external devices such as the FLD or RS-232C may
be stored in an "LF" format.
The actual codes for EIA are: "EOB (End of Block)" and "EOR (End of Record)".
When creating the machining program, select the appropriate machining conditions so
as not to exceed the machine and NC performance, capacity and limits. The examples
do not consider the machining conditions.
Do not change the fixed cycle program without prior consent from the machine
manufacturer.
6. Items related to operation
Do not enter the movable range of the machine during automatic operation. Make
sure not to place hands, legs or face near the spindle during rotation.
Always carry out dry run operation before actual machining, and confirm the machining
program, tool offset amount and workpiece coordinate system offset amount.

CAUTION
7. Items related to faults and errors
If the BATTERY LOW warning 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.
If the axis overruns or makes an abnormal noise, press the EMERGENCY STOP
button immediately, and stop the axis.
When setting the parameter not to check the overheat, the control unit and the
communication terminal may not be controlled because of overheat.
In such case, axis runaway may cause a machine breakage, an accident resulting in
injury or death, or device breakage.
To prevent the serious results, ordinarily set the parameters so that the overheat
check is valid.
8. Items related to maintenance
Do not apply voltages on the connector other than those indicated in Connection and
Maintenance manual. Doing so may lead to destruction or damage.
Incorrect connections may damage the devices, so connect the cables to the
specified connectors.
Do not connect or disconnect the connection cables between each unit while the
power is ON.
Do not connect or disconnect any PCB while the power is ON.
Do not replace the battery while the power is ON.
Do not short-circuit, charge, overheat, incinerate or disassemble the battery.
Dispose of the spent battery according to local laws.
9. Items related to servo/spindle parameters
To change the control mode to the High-gain amp (MDS-B-V14/V24) mode after
replacement of the Standard amp (MDS-B-V1/V2), it is need to change the
parameters and to adjust the servo parameters to fit to the High-gain amp.
Mode change between the Standard amp mode and the High-gain amp mode is
actually performed when the power (200V) is turned ON. Thus, when changing some
parameters unique to each amp, an alarm “7F” occurs and requests to turn the power
ON again.
Note that the alarm “7F” may occur when the amp is mounted on the machine for the
first time.
When the alarm “7F” occurs, turn the power ON again.
The alarm “7F” may not occur at second turning ON or later unless the above-
mentioned parameters are changed.
With MDS-C1 series, only the serial encoder is applied as the motor end detector.
Thus, OHE/OHA type detector cannot be used as the motor end detector.
Do not make remarkable adjustments or changes of the parameters as the operation
may became unstable.
