search mode
1 Search left stop switch only.
2 Search right stop switch, then
search left stop switch.
3 Search right stop switch, then
search left stop switch from both
sides.
4 Search left stop switch from both
sides.
5 Search home switch in negative di-
rection, reverse the direction when
left stop switch reached.
6 Search home switch in positive di-
rection, reverse the direction when
right stop switch reached.
7 Search home switch in positive di-
rection, ignore end switches.
8 Search home switch in negative di-
rection, ignore end switches.
Additional functions:
• Add 128 to a mode value for inverting
the home switch (can be used with mode
5. . . 8).
• Add 64 to a mode for searching the right
instead of the left reference switch (can be
used with mode 1. . . 4).
