Page 16: 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.
Page 17: Absolute Workpiece Positions
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. 300S...
Page 18: Zero Angle Reference Axis
- 270° ... positive Y axis 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.
Page 19: Encoder Reference Marks
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.

Error Messages If an error occurs while working with the 300S, the message will appear on the display, and provide an explanation of what caused the error. See "Error Messages" on page 101.
Page 24: Power Up
If necessary, you can change the application later in Installation Setup under Counter Settings. The 300S is now ready for the remaining setup requirements. It is now in the operating mode “Absolute”. Each active axis will have a flashing “REF” sign next to it. The following section, “Reference Mark Evaluation”, describes setting up this feature.

Page 95: Display Configuration
From an analysis of the error, it can be determined which form of compensation is required, linear, or non-linear error. The 300S provides the opportunity to compensate for these errors, and each axis can be programmed separately with the appropriate compensation.
Page 96: Linear Error Compensation
Linear Error Compensation Linear error compensation can be applied, if the results of the comparison with a reference standard show a linear deviation over the whole measuring length. In this case the error can be compensated by the calculation of a single correction factor. To calculate the linear error compensation use this formula: Correction factor LEC = ((S –...
