and may not be available for another model. Check the specification of the machine if in
doubt as to its machine-specific functions .

Grounding
Correct grounding is critical for the numerical control unit and other electrical devices.
No grounding or incorrect grounding may injure the operator or damage components
of the numerical control devices.
If the devices are not correctly grounded, inductive interference from electric motors
and appliances can lead to errors and unexpected results.

Filters are used on cooling fans to prevent dust from entering into devices. However, it
would prevent adequate cooling if the filters become clogged. It is recommended that
the user clean the filters every three months. In dusty environments such as wood
routers, clean the filters more often .

A fter turning on the power i mmediately, do not touch any of the keys on the Manual

numerical control unit. Since some of the keys on the MDI panel are dedicated to the
maintenance or other special operations, pressing any of these keys may prevent the
numerical control unit from entering its normal state. Starting the machine in the wrong

9. Trial
Never machine a workpiece without checking the machine's status at first. 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.

Feedrate
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 .

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 .

1.5.6 Speed
By pressing these keys , the spindle speed, rapid traverse speed and feed rate (machining
speed) can be adjusted. The first row controls the spindle speed, the second row controls the
rapid traverse speed and the bottom row controls feed rate.
These keys work by adjusting the speed relative to a “ base ” speed. Different modes
(Automatic, Single Block and Manual) may have different base speeds. The base speed is
set by the G-code program or the parameter.
For each row, pressing the center key sets the speed at 100% of the base speed; the LED

light in the key’s upper-left corner is lit to signify that the machine is running at 100 percent
of the base speed. Pressing the minus (-) key, decreases the base speed by a fixed percent;
pressing the plus (+) key, increases the base speed by a fixed percent. Below is an example
where the speeds are changed by 2%:

Pressing this key decreases the speed 2% for each press. The current speed
or rate is displayed on the LCD screen.
Once this key is pressed, the override ratio is set to 100%. The LED light
indicates that the current speed is the base speed.
Pressing this key increases the speed 2% for each press. The current speed
or rate is displayed on the LCD screen.

In INC mode or Manual Mode, the tool moves the Y axis in the positive direction
while +Y is pressed , and in the negative direction while – Y is pressed. In
Reference mode, pressing the +Y key homes the Y axis (finds the machine
reference on the Y axis).
In INC mode or Manual Mode, the tool moves the Z axis in the positive
direction while +Z is pressed , and in the negative direction while – Z is
pressed. In Reference mode, pressing the +Z key homes the Z axis (finds
machine reference on the Z axis).
The 4TH axis is only valid for servo-driven spindle mills. In INC mode or
Manual Mode, the spindle moves in the positive direction while +4TH is
pressed and in the negative direction while – 4TH is pressed. In Reference
mode, pressing the +4TH key homes the spindle (finds the spindle reference).
This key speeds up tool motion in Manual mode. It must be pressed in
conjunction with one of the Axis keys.
