Effects of the setting
Based on the example "set reference point" to 300 mm, you can see how this setting shifts
the working range of the axis.
This has the following effects:
● The actual position is set to the value of the reference point coordinate.
● The working range is physically shifted on the axis.
● The various points retain their original coordinates, but are now at new physical positions.
● The SYNC bit is set in the checkback signals.
