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. 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.

Refer to the following documents.

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".

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 bodily injury or when physical damage may occur if handling is mistaken.

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.

DANGER

Not applicable in this manual.

WARNING

Not applicable in this manual.

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 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.

CAUTION

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.

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.

(Continued on next page)

CAUTION

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.

CAUTION

8. Items related to maintenance Incorrect connections may damage the devices, so connect the cables to the

specified connectors. Do not apply voltages other than those indicated according to specification on the

connector. Doing so may lead to destruction or damage. Do not connect or disconnect the connection cables between each unit while the

power is ON. Do not connect or disconnect the PCBs 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 the 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 control section power supply PCB while the power is ON.

Do not replace the expansion PCB while the power is ON.

Do not replace the memory cassette while the power is ON.

Do not replace the cooling fan while the power is ON.

Do not replace the battery while the power is ON.

Be careful that metal cutting chips, etc., do not come into contact with the connector contacts of the memory cassette.

Do not replace the high-speed program server unit while the power is ON.

Before touching the unit, always touch a metal with a ground section to discharge any static electricity in the human body etc. If static electricity is not discharged, the breakdown and the malfunction of the unit are caused.

When connecting to a personal computer and a unit with the RS-232/USB interface, an electric shock or a unit failure may occur. Operate these correctly according to the manual of a unit and a personal computer. Observe the following cautions when a personal computer in an AC power supply is used. (1) For a personal computer that uses a 3-pin power plug or power plug with a ground

lead type, make sure to use a plug socket including a ground input electrode or ground the earth lead, respectively.

(2) For a personal computer that uses a 2-pin power plug without ground lead, make sure to connect the unit to the personal computer according to the following procedures. And, it is recommended to supply the same power supply line to a personal computer and the unit.

(a) Pull out the power plug of the personal computer from the AC outlet. (b) Confirm that the power plug of the personal computer has been pulled out from

the AC outlet, and connect RS-232/USB cables. (c) Insert the power plug of the personal computer into the AC outlet.
