users to ensure the safe operation of machines equipped with a CNC unit(all descriptions in thissection assume this configuration).CNC maintenance involves various dangers.CNC maintenance must be undertaken only by a qualifiedtechnician.Users must also observe the safety precautions related to the machine,as described in the relevant manual suppliedby the machine tool builder.Before checking the operation of the machine,take time to become familiar with the manuals provided by themachine tool builder and FANUC.Contents1.DEFINITION OF WARNING,CAUTION,AND NOTEs2.2.WARNINGS RELATED TO CHECK

NOTEThis manual includes safety precautions for protecting the maintenance personnel(herein referredto as the user)and preventing damage to the machine.Precautions are classified into Warnings andCautions according to their bearing on safety.Also,supplementary information is described as aNote.Read the Warning,Caution,and Note thoroughly before attempting to use the machine.WARNINGApplied when there is a danger of the user being injured or when there is a damage of both the userbeing injured and the equipment being damaged if the approved procedure is not observed.CAUTIONApplied when there is a danger of the equipment being damaged,if the approved procedure is notobserved.NOTEThe Note is used to indicate supplementary information other than Warning and Caution.?Read this manual carefully,and store it in a safe place.B62075E/04SAFETY PRECAUTIONSs32WARNINGS RELATED TO CHECK OPERATIONWARNING1.When checking the operation of the machine with the cover removed(1)The users clothing could become caught in the spindle or other components,thuspresenting a danger of injury.When checking the operation,stand away from the machineto ensure that your clothing does not become tangled in the spindle or other components.(2)When checking the operation,perform idle operation without workpiece.When aworkpiece is mounted in the machine,a malfunction could cause the workpiece to bedropped or destroy the tool tip,possibly scattering fragments throughout the area.Thispresents a serious danger of injury.Therefore,stand in a safe location when checking theoperation.2.When checking the machine operation with the power magnetics cabinet door opened(1)The power magnetics cabinet has a highvoltage section(carrying a mark).Nevertouch the highvoltage section.The highvoltage section presents a severe risk of electricshock.Before starting any check of the operation,confirm that the cover is mounted onthe highvoltage section.When the highvoltage section itself must be checked,note thattouching a terminal presents a severe danger of electric shock.(2)Within the power magnetics cabinet,internal units present potentially injurious corners andprojections.Be careful when working inside the power magnetics cabinet.3.Never attempt to machine a workpiece without first checking the operation of the machine.Before starting a production run,ensure that the machine is operating correctly by performinga trial run using,for example,the single block,feedrate override,or machine lock function orby operating the machine with neither a tool nor workpiece mounted.Failure to confirm thecorrect operation of the machine may result in the machine behaving unexpectedly,possiblycausing damage to the workpiece and/or machine itself,or injury to the user.4.Before operating the machine,thoroughly check the entered data.Operating the machine with incorrectly specified data may result in the machine behavingunexpectedly,possibly causing damage to the workpiece and/or machine itself,or injury to theuser.SAFETY PRECAUTIONSB62075E/04s4WARNING5.Ensure that the specified feedrate is appropriate for the intended operation.Generally,for eachmachine,there is a maximum allowable feedrate.The appropriate feedrate varies with theintended operation.Refer to the manual provided with the machine to determine the maximumallowable feedrate.If a machine is run at other than the correct speed,it may behaveunexpectedly,possibly causing damage to the workpiece and/or machine itself,or injury to theuser.6.When using a tool compensation function,thoroughly check the direction and amount ofcompensation.Operating the machine with incorrectly specified data may result in the machine behavingunexpectedly,possibly causing damage to the workpiece and/or machine itself,or injury to theuser.B62075E/04SAFETY PRECAUTIONSs53WARNINGS RELATED TO REPLACEMENTWARNING1.Always turn off the power to the CNC and the main power to the power magnetics cabinet.Ifonly the power to the CNC is turned off,power may continue to be supplied to the serve section.In such a case,replacing a unit may damage the unit,while also presenting a danger of electricshock.2.When a heavy unit is to be replaced,the task must be undertaken by two persons.If thereplacement is attempted by only one person,the replacement unit could slip and fall,possiblycausing injury.3.After the power is turned off,the servo amplifier and spindle amplifier may retain voltages fora while,such that there is a danger of electric shock even while the amplifier is turned off.Allowat least twenty minutes after turning off the power for these residual voltages to dissipate.4.When replacing a unit,ensure that the new unit has the same parameter and other settings as theold unit.(For details,refer to the manual provided with the machine.)Otherwise,unpredictablemachine movement could damage the workpiece or the machine itself,and present a danger ofinjury.SAFETY PRECAUTIONSB62075E/04s64WARNINGS RELATED TO PARAMETERSWARNING1.When machining a workpiece for the first time after modifying a parameter,close the machinecover.Never use the automatic operation function immediately after such a modification.Instead,confirm normal machine operation by using functions such as the single block function,feedrate override function,and machine lock function,or by operating the machine withoutmounting a tool and workpiece.If the machine is used before confirming that it operatesnormally,the machine may move unpredictably,possibly damaging the machine or workpiece,and presenting a risk of injury.2.The CNC and PMC parameters are set to their optimal values,so that those parameters usuallyneed not be modified.When a parameter must be modified for some reason,ensure that youfully understand the function of that parameter before attempting to modify it.If a parameteris set incorrectly,the machine may move unpredictably,possibly damaging the machine orworkpiece,and presenting a risk of injury.B62075E/04SAFETY PRECAUTIONSs75WARNINGS AND NOTES RELATED TO DAILYMAINTENANCEWARNING1.Memory backup battery replacementWhen replacing the memory backup batteries,keep the power to the machine(CNC)turned on,and apply an emergency stop to the machine.Because this work is performed with the poweron and the cabinet open,only those personnel who have received approved safety andmaintenance training may perform this work.When replacing the batteries,be careful not to touch the highvoltage circuits(marked andfitted with an insulating cover).Touching the uncovered highvoltage circuits presents an extremely dangerous electric shockhazard.NOTEThe CNC uses batteries to preserve the contents of its memory,because it must retain data such asprograms,offsets,and parameters even while external power is not applied.If the battery voltage drops,a low battery voltage alarm is displayed on the machine operators panelor CRT screen.When a low battery voltage alarm is displayed,replace the batteries within a week.Otherwise,thecontents of the CNCs memory will be lost.To replace the battery,see the procedure described in Section 2.8 of this manual.SAFETY PRECAUTIONSB62075E/04s8WARNING2.Absolute pulse coder battery replacementWhen replacing the memory backup batteries,keep the power to the machine(CNC)turned on,and apply an emergency stop to the machine.Because this work is performed with the poweron and the cabinet open,only those personnel who have received approved safety andmaintenance training may perform this work.When replacing the batteries,be careful not to touch the highvoltage circuits(marked andfitted with an insulating cover).Touching the uncovered highvoltage circuits presents an extremely dangerous electric shockhazard.NOTEThe absolute pulse coder uses batteries to preserve its absolute position.If the battery voltage drops,a low battery voltage alarm is displayed on the machine operators panelor CRT screen.When a low battery voltage alarm is displayed,replace the batteries within a week.Otherwise,theabsolute position data held by the pulse coder will be lost.To replace the battery,see the procedure described in Section 2.8 of this manual.B62075E/04SAFETY PRECAUTIONSs9WARNING3.Fuse replacementBefore replacing a blown fuse,however,it is necessary to locate and remove the cause of theblown fuse.For this reason,only those personnel who have received approved safety and maintenancetraining may perform this work.When replacing a fuse with the cabinet open,be careful not to touch the highvoltage circuits(marked and fitted with an insulating cover).Touching an uncovered highvoltage circuit presents an extremely dangerous electric shockhazard.Table of ContentsB62075E/04c1SAFETY
