Figure 4-33 Axis referencing in STEP 7 (referencing mode, reference cams and encoder zero mark)
Parameter: U922 index 5 (encoder actual values)
Significance:
The reference value is connected to the encoder interface via U922.i005. If reference cam
and encoder zero mark or encoder zero mark only are used for referencing, then referencing
is performed using the reference point detection in the Motion Control. However, if only a
reference cam is used for referencing, the position measured value memory in Motion
Control is used for referencing.
If reference cam and encoder zero mark or encoder zero mark only are used for referencing,
then connector KK124 (reference point measured value) should be set in U922.i005
(encoder interface reference value).
If only a reference cam is to be used for referencing, then connector KK122 (position
measured value memory) should be set in U922.i005 (encoder interface reference value).
Parameter: U923 index 1 (encoder feedback signal)
