Note!

If the drive is to stop at the next zero−pulse after detecting the mark, then an offset must be assigned,

under dnRefOffset .

· Mode 0: dnRefOffset = 65536 (º 1 motor turn)

· Mode 1: dnRefOffset = −65536 (º 1 motor turn)

Function for homing with a reference switch and TouchProbe (TP)

· In this case, the reference offset is set to dnRefOffset =0.

This applies to Modes 0 and 1, for homing with a reference switch and TouchProbe
