Parameter Descriptions
If using negative values for the OnPosn and OffPosn, the most negative value should go in
the OnPosn parameter, and the least negative value should go in the OffPosn.
If the PLS has a rollover point, and the OnPosn is greater than the OffPosn, the PLS will be
active whenever the axis is not between the On and Off positions, and inactive whenever the
axis is between the two positions. However, the PLS.#.Status will not turn on until it reaches
the OnPosn the first time.
PLS On Point
PLS.#.OnPosn
PLS.#.Status will be active when the selected source position is between the PLS.#.OnPosn
and the PLS.#.OffPosn. The terms On and Off assume the motor is traveling in a positive
direction. Assume that the PLS.#.Direction is set to "Both". When traveling in the positive
direction and the position feedback reaches the OnPosn, the PLS.#.Status will activate. As the
motor continues in the same direction, the PLS.#.Status will deactivate when feedback
position reaches or exceeds the OffPosn. If motor travel changes to the negative direction,
the PLS.#.Status will activate when position feedback reaches the OffPosn, and will
deactivate when it continues past the OnPosn. The important thing to remember is that the
PLS.#.Status will be active if between the PLS On and Off points.
If using negative values for your OnPosn and OffPosn, the most negative value should go in
the OnPosn parameter, and the least negative value should go in the OffPosn.
If the PLS has a rollover point, and the OnPosn is greater than the OffPosn, the PLS will be
active whenever the axis is not between the On and Off positions, and inactive whenever the
axis is between the two positions. However, the PLS.#.Status will not turn on until it reaches
the OnPosn the first time.
PLS Enable
PLS.#.PLSEnable
This destination is used to enable an individual PLS. A PLS can be enabled though the
Assignments view in PowerTools FM3 or from a program. If enabled, the PLS will begin to
function as soon as the drive has been homed or a DefineHome destination has been activated.
Master Posn Valid must be active (Master Define Home is activated) if using a master signal
for PLS source.
PLS Rollover Enable
PLS.#.RotaryRolloverEnable
This parameter is used to enable the RotaryRolloverPosn for the individual PLS.
