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.

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.

7.Items related to faults and abnormalities

If the battery low warning is issued, save the machining programs, tool data and parameters in an input/

output device, and then replace the battery. When the battery alarm is issued, the machining programs, tool

data and parameters may be destroyed. Reload the data after replacing the battery.

If the axis overruns or emits an abnormal noise, immediately press the emergency stop button and stop the

axis movement.

8. Items related to maintenance
