Setting Up Parameters

For example, a flying cutoff or flying shear application may use this feature to activate the

PLS to fire the knife only when the axis is moving in the positive direction.

Rotary Enable

This parameter is used to enable the RotaryRolloverPosn for this PLS.

Rollover Point

This parameter is the absolute position of the first repeat position for this PLS. When enabled

it causes the PLS to repeat every time this distance is passed. The repeating range begins at

an absolute position of zero and ends at the RotaryRolloverPosn.

For example, in a rotary application a PLS could be setup with an OnPosn of 90 degrees and

an OffPosn of 100 degrees. If the RotaryRolloverPosition is set to 360 degrees the PLS would

come on at 90, go off at 100, go on at 450 (360+90), go off at 460 (360+100), go on at 810

(2*360+90), go off at 820 (2*360+100), and continue repeating every 360 degrees forever.
