Fig. 8-8: Critical and Optimal Distance Between Home Switch and Reference
Mark
The optimum distance between the home-switch signal edge and the
reference mark is:
0.5 * distance between reference marks
To avoid having to mechanically shift the home-switch signal edge, this
procedure can be taken over by the software in parameter C012, Home
switch offset.

Fig. 8-9: How Parameter C012, Home switch offset works
When setting parameter C012, Home switch offset, always enter 0 the
first time.
Initial Startup with "Evaluation of Distance-coded Reference Marks"
If the encoder has distance-coded reference marks (type 4), C009,
Homing configuration must be set to determine the following:
•
whether the home switch should be evaluated and/or
•
in what direction the drive should move during "Homing"
In parameter:
•
C013, Distance-coded reference offsets
enter the greater and lesser distances between the reference marks.
These values can be found in the encoder specification.
