Introduction
This manual describes the specifications of MITSUBISHI CNC 700/70 Series.
To safely use this CNC unit, thoroughly study the "Precautions for Safety" on the next page
before use.
Details described in this manual
At the beginning of each item, a table indicating it’s specification according to the model.

CAUTION
The items that are not described in this manual must be interpreted as "not possible".
This manual is written on the assumption that all option functions are added.
Some functions may differ or some functions may not be usable depending on the NC
system (software) version.
General precautions
(1) When the contents of this manual is updated, the version (A, B, …) on the cover will be
incremented.
Precautions for Safety
Always read this manual, related manuals and attached documents before installation, operation,
programming, maintenance or inspection to ensure correct use.
Understand all the conditions described in this manual before using the unit.
We rank the safety precautions into "DANGER", "WARNING" and "CAUTION" for the manuals issued
by Mitsubishi, including this manual.
DANGER
WARNING
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.
Not applicable 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.
DANGER
Not applicable in this manual.
1. Items related to product and manual
The items that are not described in this manual must be interpreted as "not possible".
This manual is written on the assumption that all option functions are added.
Some functions may differ or some functions may not be usable depending on the NC
system (software) version.
2. Items related to start up and maintenance
Follow the power specifications (input voltage range, frequency range, momentary
power failure time range) described in this manual.
Follow the environment conditions (ambient temperature, humidity, vibration,
atmosphere) described in this manual.
!
Follow the remote type machine contact input/output interface described in this manual.
(Connect a diode in parallel with the inductive load or connect a protective resistor in
serial with the capacitive load, etc.)
WARNING
CAUTION
If the parameter is used to set the temperature rise detection function to invalid,
overheating may occur, thereby disabling control and possibly resulting in the axes
running out of control, which in turn may result in machine damage and/or bodily injury
or destruction of the unit. It is for this reason that the detection function is normally left
"valid" for operation.
The parameter for the temperature rise detection function will be validated forcibly
when the NC unit is turned ON.

A number of axes that are within the maximum number of axes, and that does not exceed the maximum
number given for the NC axis, spindle and PLC axis can be used.
Connection specifications of NC axis, PLC axis and spindle
There are two channels with which the servo and spindle are connected.
Maximum 8 axes can be connected with each channel.
NC axis, PLC axis, spindle : These can be connected with the optical servo communication channel (OPT).
The connection number of first axis to eighth axis is assigned to each channel.
Connect them from the first axis in order.
More than one axis must be connected with the channel 1.

1.3.1 Tape (RS-232C Input) Mode
M70 Type B M70 Type A M720 M730 M750
M system
L system
In this mode, operation is performed using the machining program data from the RS-232C interface built in
the NC unit. A paper tape reader must be provided if machining programs on paper tape are to be run.
1.3.2 Memory Mode
M70 Type B M70 Type A M720 M730 M750
M system
L system
The machining programs stored in the memory of the NC unit are run.
1.3.3 MDI Mode
M70 Type B M70 Type A M720 M730 M750
M system
L system
The MDI data stored in the memory of the NC unit is executed. Once executed, the MDI data is set to the
"setting incomplete" status, and the data will not be executed unless the "setting completed" status is
established by screen operations.
1.3.4 High-Speed Program Server Mode (CF Card in Control Unit)
M70 Type B M70 Type A M720 M730 M750
M system - - U U U
L system - - U U U
The machining program stored in CF card can be operated by installing a CF card in the control unit CF
(compact flash) card interface.
Machining programs can be copied to CF card with the front IC card or Ethernet on the input/output screen.

There are two types of the decimal point input commands and they can be selected by parameter.
(1) Decimal point input type I
When axis coordinates and other data are issued in machining program commands, the assignment of
the program data can be simplified by using the decimal point input. The minimum digit of a command
not using a decimal point is the same as the least command increment.
Usable addresses can be applied not only to axis coordinate position but also to speed commands and
dwell commands.
The decimal point position serves as the millimetre unit in the metric mode, as the inch unit in the inch
mode and as the second unit in a time designation of dwell command.
(2) Decimal point input type II
As opposed to type I, when there is no decimal point, the final digit serves as the millimetre unit in the
metric mode, as the inch unit in the inch mode and as the second unit in the time designation.
The "." (point) must be added when commands below the decimal point are required.

For axis command value, the radius designation or diameter designation can be changed over with

When the diameter designation is selected, the scale of the length of the selected axis is doubled. (For
instance, an actual length of 1 mm will be treated as 2 mm.)
This function is used when programming the workpiece dimensions on a lathe as diameters. Changing over

The above command positions the tool by rapid traverse. The tool path takes the shortest distance to the end
point in the form of a straight line.
For details on the rapid traverse feed rate of the NC, re fer to the section entitled " Rapid Traverse Rate". Since
the actual rapid traverse feed rate depends on the machine, refer to the specifications of the machine
concerned.
(1) The rapid traverse feed rate for each axis can be set independently with parameters.
(2) The number of axes which can be driven simultaneously depends on the specifications (number of
simultaneously controlled axes). The axes can be used in any combination within this range.
(3) The feed rate is controlled within the range that it does not exceed the rapid traverse rate of each axis
and so that the shortest time is taken. (Linear type)
Parameter setting enables movement at the rapid traverse rates of the respective axes independently for
each axis. In this case, the tool path does not take the form of a straight line to th e end point. (Non-Li near
