Parameter Descriptions

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 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.

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

1 2 ... 128 129 130 131 132 133 134 135 136 137 138 ... 229 230
