WARNINGS RELATED TO CHECK OPERATION
WARNING
1.
When checking the operation of the machine with the cover removed
(1) The user’s clothing could become caught in the spindle or other components, thus
presenting a danger of injury . When checking the operation, stand away from the machine
to 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 a
workpiece is mounted in the machine, a malfunction could cause the workpiece to be
dropped or destroy the tool tip, possibly scattering fragments throughout the area. This
presents a serious danger of injury . Therefore, stand in a safe location when checking the
operation.
2.
When checking the machine operation with the power magnetics cabinet door opened
(1) The power magnetics cabinet has a high–voltage section (carrying a
mark). Never
touch the high–voltage section. The high–voltage section presents a severe risk of electric
shock. Before starting any check of the operation, confirm that the cover is mounted on
the high–voltage section. When the high–voltage section itself must be checked, note that
touching a terminal presents a severe danger of electric shock.
(2) Within the power magnetics cabinet, internal units present potentially injurious corners and
projections. 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 performing
a trial run using, for example, the single block, feedrate override, or machine lock function or
by operating the machine with neither a tool nor workpiece mounted. Failure to confirm the
correct operation of the machine may result in the machine behaving unexpectedly, possibly
causing 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 behaving
unexpectedly , possibly causing damage to the workpiece and/or machine itself, or injury to the
user.

5.
Ensure that the specified feedrate is appropriate for the intended operation. Generally , for each
machine, there is a maximum allowable feedrate. The appropriate feedrate varies with the
intended operation. Refer to the manual provided with the machine to determine the maximum
allowable feedrate. If a machine is run at other than the correct speed, it may behave
unexpectedly , possibly causing damage to the workpiece and/or machine itself, or injury to the
user.
6.
When using a tool compensation function, thoroughly check the direction and amount of
compensation.
Operating the machine with incorrectly specified data may result in the machine behaving
unexpectedly , possibly causing damage to the workpiece and/or machine itself, or injury to the
user.

WARNINGS RELATED TO REPLACEMENT
WARNING
1.
Always turn off the power to the CNC and the main power to the power magnetics cabinet. If
only 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 electric
shock.
2.
When a heavy unit is to be replaced, the task must be undertaken by two persons or more. If
the replacement is attempted by only one person, the replacement unit could slip and fall,
possibly causing injury.
3.
After the power is turned off, the servo amplifier and spindle amplifier may retain voltages for
a while, such that there is a danger of electric shock even while the amplifier is turned off. Allow
at 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 the
old unit. (For details, refer to the manual provided with the machine.) Otherwise, unpredictable
machine movement could damage the workpiece or the machine itself, and present a danger of
injury .

WARNINGS RELATED TO PARAMETERS
WARNING
1.
When machining a workpiece for the first time after modifying a parameter, close the machine
cover. 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 without
mounting a tool and workpiece. If the machine is used before confirming that it operates
normally , 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 usually
need not be modified. When a parameter must be modified for some reason, ensure that you
fully understand the function of that parameter before attempting to modify it. If a parameter
is set incorrectly, the machine may move unpredictably, possibly damaging the machine or
workpiece, and presenting a risk of injury.

WARNINGS AND NOTES RELATED TO DAILY
MAINTENANCE
WARNING
1.
Memory backup battery replacement
When replacing the memory backup batteries, keep the power to the machine (CNC) turned on,
and apply an emergency stop to the machine. If this work is performed with the power on and
the cabinet open, only those personnel who have received approved safety and maintenance
training may perform this work.
When replacing the batteries, be careful not to touch the high–voltage circuits (marked
and
fitted with an insulating cover).
Touching the uncovered high–voltage circuits presents an extremely dangerous electric shock
hazard.
NOTE
The CNC uses batteries to preserve the contents of its memory , because it must retain data such as
programs, 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 operator’s panel
or CRT screen.
When a low battery voltage alarm is displayed, replace the batteries within a week. Otherwise, the
contents of the CNC’s memory will be lost.
To replace the battery, see the procedure described in Section 2.8 of this manual.
