PLS Rollover Position

PLS.#.RotaryRolloverPosn

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.

PLS Source

PLS.#.Source

PLSs can be assigned to three different sources: MotorPosnFeedback, MotorPosnCommand, or MasterPosnFeedback. This parameter determines which position signal the PLS uses to reference its OnPosn and OffPosn in order to determine its PLS.#.Status parameter.

PLS Status

PLS.#.Status

This source is active when the position of the PLS source (motor or master) is greater than or equal to the OnPosn and less than the OffPosn.

Positive Direction

PositiveDirection

This bit is used to select which direction of motor rotation is considered motion in the positive direction. Select from CW or CCW.

Position Command

PosnCommand

Position command sent to the EN drive by the FM-3. This parameter does not take following error into account. See also PosnFeedback and FollowingError. Units are in user units.

Position Error Integral Enable

PosnErrorIntegralEnable

This parameter is used to enable the position error integral compensation. See also Position Error Integral Time Constant.
