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.
