Setting Up Parameters
is only updated when Index# is run. The direction of the PLS does not matter, the
Index.#.PLSStatus will activate and deactivate the same incremental distance from the start
of the index.
PLS On Point
This parameter is an incremental distance from the start position of the index, at which the
PLS.#.Status will become active. It is an unsigned value in user units. The On Point must
always be less than the Off Point.
PLS Off Point
This parameter is an incremental distance from the start position of the index, at which the
PLS.#.Status will deactivate. It is an unsigned value in user units. The Off Point must always
be greater than the On Point. If the Off Point is larger than the Distance parameter in an
Incremental type of index, the PLS Status will never deactivate until the index is run again.
Example 1:
Index 0 is an Incremental index with a distance of 5 Revs. The PLS On Point is set to 1 Rev,
and the PLS Off Point is set to 4 Revs. A home is completed, and Position Feedback is equal
to 0.0 Revs.
If Index 0 is run, the Index.0.PLSStatus will activate when the feedback position reaches 1
Rev and remain active until feedback position reaches 4 Revs, and deactivate. At the end of
Index 0, position feedback is equal to 5 Revs. If we initiate Index 0 again, Index.0.PLSStatus
will activate 1 Rev into the index, or at 6 Revs. It will remain active until position feedback
reaches 9 Revs, and deactivate. This index could be run over and over again, and
Index.0.PLSStatus will activate 1 Rev from the starting position and deactivate 4 Revs from
the starting position every time.
Example 2:
Index 1 is an Incremental index with a distance of -10 revs. The PLS On Point is set to 4 Revs,
and the PLS Off Point is set to 6 Revs. A home is completed, and Position Feedback is equal
to 0.0 Revs.
If Index 1 is run, the Index.1.PLSStatus will activate when the position feedback reaches -4
Revs (or 4 Revs from the start of the index). Index.1.PLSStatus will then deactivate when
position feedback reaches -6 Revs (or 6 Revs from the start of the index). If Index 1 is run
again, Index.1.PLSStatus will activate and deactivate at -14 Revs and -16 Revs respectively.
Index PLS’s can be used on any type of an index.
If an index is so short (possible in the case of an absolute index) that it reaches the On Point,
or incremental distance, into the index, but never reaches the Off Point, the Index.#.PLSStatus
will remain active until the index is run again.
Similarly, if the index is so short that it never reaches the On Point, the Index.#.PLSStatus
will never activate.
