FM-3 Programming Module Reference Manual
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.
