the "Precautions for Safety" on the following page to ensure safe use of this NC unit.
Details described in this manual
CAUTION
For items described as "Restrictions" or "Usable State" in this manual, the instruction manual issued by
the machine tool builder takes precedence over this manual.
Items not described in this manual 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 tool builder before starting use.
Refer to the Instruction Manual issued by each machine tool builder for details on each machine tool.
Some screens and functions may differ depending on the NC system (or its version), and some functions
may not be possible. Please confirm the specifications before use.
General precautions
(1) Refer to the following documents for details on handling
MITSUBISHI CNC M700V/M70V Series Instruction Manual ............ IB-1500922
Precautions for Safety
Always read the specifications issued by the machine tool builder, 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".
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.
The following sings indicate prohibition and compulsory.
The meaning of each pictorial sing is as follows.
DANGER
When the user may be subject to imminent fatalities or major injuries if handling is mistaken.
WARNING
When the user may be subject to fatalities or major injuries if handling is mistaken.
CAUTION
When the user may be subject to injuries or when physical damage may occur if handling is mistaken.
This sign indicates prohibited behavior (must not do).
For example, indicates "Keep fire away".
This sign indicated a thing that is pompously (must do).
For example, indicates "it must be grounded".

General instruction
Earth ground
Mitsubishi CNC is designed and manufactured solely for applications to machine tools to be used for industrial
purposes.
Do not use this product in any applications other than those specified above, especially those which are
substantially influential on the public interest or which are expected to have significant influence on human lives or
properties.
Not applicable in this manual.
1. Items related to operation
If the operation start position is set in a block which is in the middle of the program and the program is
started, the program before the set block is not executed. Please confirm that G and F modal and
coordinate values are appropriate. If there are coordinate system shift commands or M, S, T and B
commands before the block set as the start position, carry out the required commands using the MDI, etc.
If the program is run from the set block without carrying out these operations, there is a danger of
interference with the machine or of machine operation at an unexpected speed, which may result in
breakage of tools or machine tool or may cause damage to the operators.
Under the constant surface speed control (during G96 modal), if the axis targeted for the constant surface
speed control moves toward the spindle center, the spindle rotation speed will increase and may exceed
the allowable speed of the workpiece or chuck, etc. In this case, the workpiece, etc. may jump out during
machining, which may result in breakage of tools or machine tool or may cause damage to the operators.
For Safe Use
DANGER
WARNING
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 tool builder takes precedence over this manual.
Items not described in this manual 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 tool builder before starting use.
Refer to the Instruction Manual issued by each machine tool builder for details on each machine tool.
Some screens and functions may differ depending on the NC system (or its version), and some functions
may not be possible. Please confirm the specifications before use.
2. Items related to operation
Before starting actual machining, always carry out graphic check, dry run operation and single block
operation to check the machining program, tool compensation amount, workpiece compensation amount
and etc.
If the workpiece coordinate system offset amount is changed during single block stop, the new setting will
be valid from the next block.
Turn the mirror image ON and OFF at the mirror image center.
If the tool compensation amount is changed during automatic operation (including during single block
stop), it will be validated from the next block or blocks onwards.
3. Items related to programming
The commands with "no value after G" will be handled as "G00".
";" "EOB" and "%" "EOR" are expressions 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, and make sure that
the performance, capacity and limits of the machine and NC are not exceeded. The examples do not
consider the machining conditions.
Do not change fixed cycle programs without the prior approval of the machine tool builder.
When programming the multi-part system, take special care to the movements of the programs for other
part systems.
CAUTION
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 end-
users 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.
