CAUTION2. Items related to installation and assemblyGround the signal cables to ensure stable system operation. Also ground the NC unitmain frame, power distribution panel and machine to one point, so they all have thesame potential.3. Items related to preparation before useAlways set the stored stroke limit. Failure to set this could result in collision with themachine 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 operationIf the tool compensation amount or workpiece coordinate system offset amount ischanged during automatic operation (including during single block stop), the changeswill 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 usethe transfer function to transfer all necessary data to another storage device beforeformatting.Even if the tool compensation amount write command, parameter write command orvariable data write command is executed with graphic check, the data will be actuallywritten in, and the original data will be overwritten.Pay close attention to the sequence operation when carrying out forced datasetting (forced output) in the I/F diagnosis screen during machineoperation.To prevent influence from data omission and data transformation in the communicationcircuit, 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 programmingBecause of key chattering, etc., during editing, "NO NOS. FOLLOWING G" commandsbecome a "G00" operation during running." ; ", "EOB", "%", and "EOR" are symbols used for explanation. The actual codes forISO 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 orRS-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 toolbuilder.(Continued on next page)

CAUTION6. Items related to operationStay out of the moveable range of the machine during automatic operation. Duringrotation, 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 isstarted, the program before the set block is not executed. If there are coordinatesystem shift commands or M, S, T, and B commands before the block set as thestarting position, carry out the required commands using the MDI, etc. There is adanger of interference with the machine if the operation is started from the set startingposition 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 positionother than the mirror image center.7. Items related to faults and abnormalitiesIf the battery low warning is issued, save the machining programs, tool data andparameters in an input/output device, and then replace the battery. When the batteryalarm 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 emergencystop button and stop the axis movement.(Continued on next page)

CAUTION8. Items related to maintenanceIncorrect connections may damage the devices, so connect the cables to thespecified connectors.Do not apply voltages other than those indicated according to specification on theconnector. Doing so may lead to destruction or damage.Do not connect or disconnect the connection cables between each unit while thepower 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 connectorcontacts 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 anystatic electricity in the human body etc.If static electricity is not discharged, the breakdown and the malfunction of the unit arecaused.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 isused.(1) For a personal computer that uses a 3-pin power plug or power plug with a groundlead type, make sure to use a plug socket including a ground input electrode orground the earth lead, respectively.(2) For a personal computer that uses a 2-pin power plug without ground lead, makesure to connect the unit to the personal computer according to the followingprocedures.And, it is recommended to supply the same power supply line to a personalcomputer 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 fromthe AC outlet, and connect RS-232/USB cables.(c) Insert the power plug of the personal computer into the AC outlet.
