  • Page 14: I - 1 Nd 280 Position Display Unit

    I – 1 ND 280 Position Display Unit The ND 280 position display unit from HEIDENHAIN is designed for measuring devices, adjustment and testing equipment, automated tasks, as well as infeed and positioning tasks with one axis that can be moved manually.

  • Page 15: I - 2 Fundamentals Of Positioning

    I – 2 Fundamentals of Positioning Datums The workpiece drawing identifies a certain point on the workpiece (usually 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 16: Actual Position, Nominal Position And Distance-To-Go

    Actual position, nominal position and distance-to-go The position of the length gauge at any given moment is called the actual position, while the position that the length gauge is to move to is called the nominal position. The distance from the nominal position to the actual position is called the distance-to-go (see Fig.

  • Page 17: Absolute Workpiece Positions

    Absolute workpiece positions Each position on the workpiece is uniquely identified by its absolute coordinates (see Fig. I.5). Example: Absolute coordinates of position 1: Z = 20 mm If you are drilling or milling a workpiece according to a workpiece drawing with absolute coordinates, you are moving the tool or length gauge to the value of the coordinates.

  • Page 18: Incremental Position Encoders

    Incremental position encoders Incremental linear and rotary encoders from HEIDENHAIN convert the movements of, for example, a length gauge into electrical signals. A position display unit, such as the ND 280, constantly evaluates these signals and calculates the actual positions of the length gauge, which it displays as a numerical value on the screen.

  • Page 19: Reference Marks

    Reference marks Encoders normally contain one or more reference marks (see Fig. I.9) which the ND 280's 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. Encoders with distance-coded reference marks have marks separated by a specific encryption pattern that allows the ND 280 to use any two pair of marks along the length of the encoder to re-...

    This error can either be linear or non-linear. You can determine these errors with a reference measurement system, e.g. the VM 101 from HEIDENHAIN. From an analysis of the error it can be determined which form of compensation is required (linear or non-linear).

  • Page 50: Linear Error Compensation (Not For Rotary Encoders)

    Linear error compensation (not for rotary encoders) 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 ND 280 can compensate the error mathematically by calculating the LEC correction factor.

  • Page 51: Non-Linear Error Compensation

    Non-linear error compensation  Non-linear error compensation is available for encoders with reference marks and for absolute encoders.  If non-linear error compensation has been defined, no error compensation will be applied until the reference marks have been crossed. Non-linear error compensation should be applied if the results of the comparison with a reference standard show an alternating or oscillating deviation.
