Precautions for Safety
Always read the specifications issued by the MTB, 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.
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.

DANGER

WARNING
1. Items related to program development
Do not assign any startup switch for C80 on GOT's touch key. If a communication fault (including cable discon-
nection) occurs between GOT and CNC C80, the communication will be suspended and the GOT will become in-
operative. 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.
2. Items related to operation
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. 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.
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 ma-
chine tool builder (MTB) 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 the applicable functions are included. Some of them, however,
may not be available for your NC system. Refer to the specifications issued by the machine tool builder before use.
Refer to the Instruction Manual issued by each MTB 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.
Do not connect NC system to the Internet-connected network.
To maintain the safety of the NC system against unauthorized access from external devices via the network, take
appropriate measures.
2. Items related to installation and assembly
Ground the signal cables to ensure stable system operation. Also ground the NC unit main frame, power distribu-
tion 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 input/output device cable. Failure to do so could
damage the input/output 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 op-
eration (including during single block stop), the changes will be valid from the command in next block or after sev-
eral 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.
Pay close attention to the sequence operation when carrying out forced data setting (forced output) in the I/F di-
agnosis 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 MTB.
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 for ISO are "CR, LF" ("LF") and
"%". "%" and "EOR" are represented by "%" in ISO.
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 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 MTB.
6. Items related to operation
Do not enter the machine’s movable range during automatic operation. During rotation, keep your 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 in the drive unit side, immediately replace the battery. Replace the batteries
while applying the drive unit's control power.
If the axis overruns or emits an abnormal noise, immediately press the emergency stop button and stop the axis
movement.
Turn OFF the power immediately if any smoke, abnormal noise or odor is generated from the controller, drive unit
or motor.
8. Items related to maintenance
Incorrect connections may damage the devices. Always connect the cables to the indicated connectors.
Do not apply voltages other than those indicated according to specification on the connector. Failure to observe
this could cause bursting, damage, etc.
Do not connect or disconnect the connection cables between each unit while the power is ON.
Do not connect the cable by pulling on the cable wire.
Do not short circuit, charge, overheat, incinerate or disassemble the battery.
Dispose the spent battery according to local laws.
Dispose the spent cooling fan according to local laws.
Do not replace each control unit while the power is ON.
Do not replace the operation panel I/O unit while the power is ON.
Do not replace the cooling fan while the power is ON.
