Setting Up Parameters
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.
