Master Axis Feedback Selector
MasterAxis.SpeedFeedbackSelector
The MasterAxis.Speed Feedback Selector parameter determines where the feedback device for the master signal is connected to. Early releases of the

SM-EZMotion Module Temperature
ModuleTemperature
This parameter displays the current temperature measured on the
When temperature reported by module reaches or exceeds 84ºC,the internal fan of the Unidrive SP will be forced to full speed. The fan will remain at full speed until the temperature drops below 79ºC.
Motion Stop
MotionStop
This destination is used to stop all motion operating without stopping programs. MotionStop can be activated through an assignment, or in a user program. This function is level sensitive, meaning that as long as MotionStop is active, all motion will be prevented. If a program has a motion statement, the program will wait on that line of code until the MotionStop function has been deactivated. If motion is in progress when MotionStop is activated, the profile will decelerate to zero velocity at the deceleration rate specified in the Stop.Decel parameter. All motion will stop using a realtime deceleration, regardless of the motions original timebase.

This parameter is used to select the motor type.

Unidrive SP Overload Accumulator
OverloadAccumulator
This parameter gives an indication of the motor temperature based on a simple thermal model. The formula for the thermal model is a function of the current demand and a thermal time constant of the motor (parameter 4.15 and found in .ddf file). This
Note
The overload accumulator is reset to zero on
PLS Direction
PLS.#.Direction
This parameter specifies the direction of motion that a particular PLS output will function. If set to Both, the PLS will activate regardless of whether the axis is moving in the positive or negative direction. If set to Plus, the PLS will activate only when the axis is moving in the positive direction. If set to Minus, the PLS will activate only when the axis is moving in the negative direction. A flying cutoff or flying shear application may use this feature to activate the PLS to fire the knife only when the axis is moving in the positive direction.
PLS Off Point
PLS.#.OffPosn
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 you are 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 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
