Initial Startup with "Evaluation of Distance-coded Reference Marks"

DOK-ECODR3-FL*-04VRS**-FK01-EN-P
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.
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.
