The homing procedures (with homing switch and encoder zero mark)
implemented up to V.1.32 are only partly suitable for rotary axis
applications. Elaborate adjustments (adapter gears, etc.) have to be
performed in order to make use of the present homing procedures.
New homing procedures have therefore been implemented:
1. Homing with homing switch only
2. Homing with encoder zero mark only
3. Use of a reversing switch during homing.
9.4.23.1 Homing with homing switch only
Homing and referencing are governed solely by the homing switch. The
zero mark of the encoder is disregarded.
1. New machine datum MD8 for defining referencing
2. 0 = Homing with bero and zero mark (<V1.4x)
1 = Homing with bero only
2 = Homing with zero mark only
