Deceleration

The Deceleration parameter specifies the deceleration value to be used during the index in

user units.

Enable Index PLS

This check box enables (when checked) or disables the Index PLS function.

An Index PLS is similar to a global PLS (explained in the PLS View section), but is

incremental in nature. The Index PLS has On and Off points just like a global PLS, but the

On and Off points are specified as an incremental distance from the start of the index, instead

of absolute positions. Each index has its’ own On and Off points, and the Index.#.PLSStatus

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.
