Readout Parameter Access Code
Readout Parameter Access Code
An access code must be entered before machine-related installation
parameters can be set or changed. This prevents inadvertent
adjustments to the installation setup parameters.
Access to Machine Parameter Operations
Refer to the Setup section also.
Begin by pressing the SETUP soft key.
Press the soft key INSTALLATION SETUP.
Press the access code numbers 8891 using the numeric key pad.
Press the ENTER key
The readout is now ready for machine parameter setting operations.
IMPORTANT!
The access code is 8891.
IMPORTANT!
To prevent setup parameters from being changed, remove
this page from the Reference Manual after initially setting
up the readout system. Retain this information in a safe
place for future use.

I - 1 Fundamentals of Positioning
I - 1 Fundamentals of Positioning
Datums
The workpiece drawing identifies a certain point on the workpiece
(example: “a corner”) as the absolute datum, and perhaps one, or
more other points as relative datums.
The datum setting procedure establishes these points as the origin of
the absolute, or relative coordinate systems. The workpiece, which is
aligned with the machine axes, is moved to a certain position relative
to the tool. The display is set either to zero, or to another appropriate
value (e.g., to compensate for tool radius).
Actual Position, Nominal Position, and
Distance-To-Go
The position of the tool at any given moment is called the ACTUAL
POSITION I, while the position that the tool is to move to is called the
NOMINAL POSITION S. The distance from the nominal position to
the actual position is called the DISTANCE-TO-GO R.

300S 3
I - 1 Fundamentals of Positioning
Absolute Workpiece Positions
Each position on the workpiece is uniquely identified by its
absolute coordinates.
Example: Absolute coordinates of position 1:
X = 20 mm
Y = 10 mm
Z = 15 mm
If you are drilling, or milling a workpiece according to a workpiece
drawing with absolute coordinates, the tool is moving to the value of
the coordinates.
Incremental workpiece positions
A position can also be referenced to the preceding nominal position.
In this case the relative datum is always the last nominal position.
Such coordinates are referred to as incremental coordinates
(increment = increase). They are also called incremental, or chain
dimensions, since the positions are defined as a chain of dimensions.
Incremental coordinates are designated with the prefix I.
Example: Incremental coordinates of position 3referenced
to position 2.
Absolute coordinates of position 2:
X = 10 mm
Y = 5 mm
Z = 20 mm
Incremental coordinates of position 3:
IX = 10 mm
IY = 5 mm
IZ = 20 mm
If you are drilling, or milling a workpiece according to a drawing with
incremental coordinates, you are moving the tool by the value of
the coordinates.

I - 1 Fundamentals of Positioning
Zero Angle Reference Axis
The Zero Angle Reference Axis is the 0.0° position. It is defined as
one of the two axes in the plane of rotation. The following table
defines the Zero Angle where the position of the angle is zero for the
three possible planes of rotation.
For angular positions, the following reference axes are defined:
Positive direction of rotation is counterclockwise if the working plane
is viewed in the negative tool axis direction.
EXAMPLE: Angle in the working plane X / Y
Reading head position
The reading head position provides feed back to the 300S that
converts the movement of the machine axes into electrical signals.
The 300S constantly evaluates these signals, and calculates the actual
positions of the machine axes, which it displays as a numerical value
on the screen.
If there is an interruption in power, the calculated position will no
longer correspond to the actual position. When power is restored, you
can re-establish this relationship by using the reference marks on the
provided on the scale. The 300S provides the Reference Mark
Evaluation feature (REF).

300S 5
I - 1 Fundamentals of Positioning
Encoder Reference Marks
Encoders normally contain one or more reference marks which the
300S Reference Mark Evaluation feature uses to re-establish datum
positions after a power interruption. There are two main options
available for reference marks; fixed and distance-coded.
Position Trac (Distance-coded reference marks): Encoders that have
marks separated by a specific encryption pattern allows the 300S to
use any two pair of marks along the length of the encoder to re-
establish the prior datums. This configuration means that the operator
only has to travel less than two inches any where along the encoder,
to re-establish the datums when the 300S is turned back on.
Fixed reference marks: Encoders that have one or more marks on
fixed intervals, have to re-establish the datums correctly. It is
necessary to use the same exact reference mark, during the
Reference Mark Evaluation routine, that was used when the datum
was first established.
The established datums’ cannot be restored from one
power cycle to the next if the reference marks were not
crossed before the datums were set
