whether the final move to the marker is required. Four options are
outlined in the table below.
An example of each option is given on the following pages.
Option 1 Example
When these parameters are set, the axis moves one revolution of the
feedback device in the direction and at the speed that the Home Axis
command specifies when looking for the marker.
Option Final Move to Which Marker?
parameter is set to: Final Move to Marker?
parameter is set to:
1 0 No (0)
2 0 Yes (1)
3 1 No (0)
4 1 Yes (1)
Parameters: Equals:
Final Move to Which Marker? 0
Final Move to Marker? No (0)
If the marker is: Then:
Found during that one
revolution move The current position of the axis is set to the
configured
Home Position ± the distance to the
marker nearest the start position + Home Calibration.
Not found during that one
revolution move The problem is reported to the SLC processor.
IMPORTANT
This configuration is typical for a unidirectional axis
(i.e., axis that only moves in one direction).
