Precautions
This section enumerates safety precautions for protecting the user
and preventing damage to the machine. Read the contents of this
part thoroughly before attempting to use the machine.
1. The working temperature for the Numerical Control (NC) unit
and its cable cabinet is 0 to 45°C (32°F to 113°F). No freezing is
allowed. The temperature variation should be less than 1.1°C/min
(2°F/min). Humidity should be kept below 90% Relative Humidity,
non-condensing and without frost; 75% Relative Humidity or lower is
more desirable.
2. For storage, the temperature range should be kept within
–20°C to 60°C (-4°F to 140°F) non-condensing and without frost.
All devices should be placed indoors and away from sunshine, dust,
eroding gases and moisture.
3. Impact during transportation or other situations should be less
than 5.9 m/s (0.6 g) for vibrations in the range between 10 to 60 Hz.
4. Correct grounding is critical for the NC unit and other electrical
devices. No grounding or incorrect grounding may injure the
operator or damage components of the NC devices. If the devices
are not correctly grounded, inductive interference from electric
motors and appliances can give errors and unexpected results.
5. Filters are used on cooling fans to prevent dust from entering
into devices. However, after time filters become clogged, preventing
adequate cooling. Clean the filters every three months. In dusty
environments such as wood routers, clean the filters more often.
6. After a long period of non-operation, NC devices should be
cleaned and dried. Also check the wiring and ground connections.
Once power is resumed after non-operation, observe the operation
for several hours to make sure there is no unexpected behavior.
7. Never machine a workpiece without first checking the

II
machine's status. Before using the machine for a production run,
make sure that the machine operates correctly by doing a trial run
including, for example, a single block with a feedrate override or a
machine lock function. Another possibility is to do the trial run
without a tool or workpiece mounted. Failure to confirm the
correct operation with a trial run may result in unexpected motion or
behavior that can damage the workpiece, damage the machine, or
injure the operator.
8. Before operating the machine, thoroughly check the entered
data, including parameters, program and settings. Operating the
machine with incorrectly specified data may also result in
unexpected motion or behavior that can damage the workpiece,
damage the machine, or injure the operator.
9. Ensure that the specified feedrate is appropriate for the
intended operation. The appropriate feedrate varies with the
operation. Generally each machine has a maximum allowable
feedrate found in the machine's operation manual. If a machine is
run at other than the correct feedrate or if the maximum allowable
feedrate is exceeded, unexpected motion or behavior may result that
can damage the workpiece, damage the machine, or injure the
operator.
10. When using the tool compensation function, thoroughly check
the direction and amount of compensation for each tool. Operating
the machine with incorrectly specified data may produce unexpected
motion or behavior that can damage the workpiece, damage the
machine, or injure the operator.
11. Usually, there is no need to change the factory-set
parameters of the NC unit and PMC. However, when there is no
choice other than to change a parameter, be sure you fully
understand the function of the parameter before making any change.
Failure to set a parameter correctly may produce unexpected motion
or behavior that can damage the workpiece, damage the machine,
or injure the operator.
12. Immediately after switching on the power, do not touch any of

III
the keys on the Manual Data Input (MDI) panel until the position
display or alarm screen appears on the NC unit. Since some of the
keys on the MDI panel are dedicated to maintenance or other special
operations, pressing any of these keys may prevent the NC unit from
entering its normal state. Starting the machine in the wrong state
may cause unexpected motion or behavior.
13. While the operator’s manual supplied with an NC unit provides
an overall description of the machine’s functions, some functions are
specific for that machine alone and may not be available for another
model. Check the specification of the machine if in doubt as to its
machine-specific functions.

1 Introduction
Overall layout
The user operates the mill either through the Numerical Control Unit
(NCU) or a Hand Pendant (optional). RS232 allows the user to
exchange data between the NCU and other computers. A PS/2
connector in the Data Exchange Port lets the user plug in a
keyboard.
