FM-3 Programming Module Reference Manual
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.
Motor Type
MotorType
This parameter is used to select the motor type.
Name
Name
User name for this FM-3 axis can have a length up to 12 characters. This can be used to help
differentiate setup files.
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.
