- Page 2 The ND 510 and ND 550 digital readouts accept HEIDENHAIN linear encoders with sinusoidal output signals. These linear encoders have one or more reference marks, preferably of the distance- coded type. When a reference mark is crossed over, a signal is generated which identifies that position as a reference point.
- Page 3 Datum Setting Functions The special functions which your display unit is capable of allow you to define a workpiece edge or the centerline between two workpiece edges as the datum. With the SPEC FCT feature, the display unit takes into account the tool diameter you entered in operating parameter P25.
- Page 4 For every axis compensation values can be entered over 16 compensation points. To determine the compensation values with a comparator system from HEIDENHAIN, such as VM 101, you must select the REF display. Selecting the Compensation Value Table Select the operating parameter P00 and enter the code number 105 296. Use...
- Page 5 Working with Scaling Factors The ND 510 and the ND 550 can display the axis traverse lengthened or shortened by a scaling factor. You enter a scaling factor separately for each axis in the user parameter P12, then activate the scaling factor function with the user parameter P11.
- Page 6 Operating Parameters User Parameters User parameters are operating parameters that can be changed without entering the codes: P00 to P25 Axis assignment Parameters which are entered separately for each axis have axis codes: "1" signifies the X-axis, "2" the Y-axis, and (with the ND 550) "3" the Z-axis. A point separates the axis code from the parameter number.
