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.
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. Confirm with 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 installation and assembly
Ground the signal cables to ensure stable system operation. Also ground the NC unit main frame, power
distribution panel and machine to one point, so they all have the same potential.
3. Items related to preparation before use
Always set the stored stroke limit. Failure to set this could result in collision with the machine end.
Always turn the power OFF before connecting/disconnecting the I/O device cable. Failure to do so could
damage the I/O device and NC unit.

4. Items related to screen operation
If the tool compensation amount or workpiece coordinate system offset amount is changed during
automatic operation (including during single block stop), the changes will be valid from the command in
next block or after several subsequent blocks.
All of the various data in the NC memory is erased when formatting. Be sure to use the transfer function to
transfer all necessary data to another storage device before formatting.
Even if the tool compensation amount write command, parameter write command or variable data write
command is executed with graphic check, the data will be actually written in, and the original data will be
overwritten.
Pay close attention to the sequence operation when carrying out forced data setting (forced output) in the I/
F diagnosis screen during machine operation.
The program including a character of any language other than the display language is not correctly
displayed. Do not edit such a program. Any part of the program other than the comment part may also be
changed if edited.
To prevent influence from data omission and data transformation in the communication circuit, always
verify the data after inputting and outputting machining programs.
Do not change setup parameters without prior approval from the machine tool builder.
5. Items related to programming
Because of key chattering, etc., during editing, "NO NOS. FOLLOWING G" commands become a "G00"
operation during running.
" ; ", "EOB", "%", and "EOR" are symbols used for explanation. The actual codes for ISO are "CR, LF"
("LF") and "%".
The programs created on the Edit screen are stored in the NC memory in a "CR, LF" format, however, the
programs created with external devices such as the FD 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)".
Do not change the fixed cycle program without prior approval from the machine tool builder.
6. Items related to operation
Stay out of the moveable range of the machine during automatic operation. During rotation, keep hands,
feet and face away from the spindle.
Carry out dry operation before actually machining, and confirm the machining program, tool offset and
workpiece coordinate system offset.
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.
Program so the mirror image function is turned ON/OFF at the mirror image center. The mirror image center
will deviate if the function is turned ON/OFF at a position other than the mirror image center.
