This check box removes the unassigned sources and destinations from this view. It allows the user to quickly see how many
sources and destinations have been assigned.
Assignments that Automatically Use Position Capture
Certain assignments (Sources or Destinations) automatically generate position capture data internally for greater performance
and accuracy. This captured data is used by the FM-3 module, but is not directly available to the user. Following is a list of
assignments that automatically generate or use captured data.
Sources that generate capture data
Module Inputs – The FM-3 Module Inputs (not base drive inputs) are constantly monitored by the processor, and when
activated will automatically capture related data. The processor controls all resetting requirements. The capture only occurs
on the rising edge of an input. When the input is activated, the captured data will automatically be passed to the destination
that it is assigned to. The destination may then use the captured data to accurately initiate motion (if it is a motion-related
destination).
Motor Encoder Marker – The rising edge of the motor encoder marker pulse will automatically capture data. This will allow
the user to accurately initiate motion on the rising edge of the motor encoder marker pulse. The falling edge of the marker
pulse does not capture data.
Master Encoder Marker – The rising edge of the master encoder marker pulse will automatically capture data. This allows
the user to accurately initiate motion on the rising edge of the master encoder marker pulse. The falling edge of the marker
pulse does not capture data.
Index/Jog Command Complete – Activation of the command complete signal at the end of indexes and jogs will
automatically capture data. A subsequent index, jog, or dwell can then use the captured data to start itself extremely accurately
at the end of the previous motion.
Index/Jog At Velocity – Activation of the command complete signal at the end of indexes and jogs will automatically capture
data. A subsequent index, jog, or dwell can then use the captured data to start itself extremely accurately at the end of the
previous motion.
PLS Status – A rising or a falling edge of a Global PLS will automatically capture data for use in initiating motion. In order
to accurately initiate motion from a Global PLS, an assignment can be made from PLS.#.Status to the initiate destination.
Destinations that use captured data:
Index/Jog Initiates – When one of the sources listed above is assigned to an Index or Jog Initiate, the captured information
is automatically applied to the index starting point. This offers extremely high accuracy for initiation of motion, which is
beneficial especially in synchronized applications.
Index.#.SensorTrigger – The sensor trigger destination used in registration indexes can use captured data to accurately
calculate the ending position of the index based on the Registration Offset parameter. The Offset distance is added to the
captured position to get the accurate stopping position for the registration index.
