Sources that generate capture data
Drive Inputs 1-15
The Epsilon EP-P 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.
3.28 Selector View
The Selector view is located under I/O Setup in the Hierarchy Tree on the left of the view.
Figure 95: Selector View
The selector allows conservation of the number of input lines by using a binary input conversion to decimal. The binary select lines are set up
by assigning sources to the Selector.Select destinations on the Assignments view. In most cases, hardware inputs are assigned to the
Selector.Select functions (see Figure 96).
Based on the status of the binary select lines, a Selector.Selection source will be active when the Selector.SelectorInitiate destination is
activated.
At the top of the Selector view, the Selector Input Destinations scroll box defines how many binary select lines will be used. The number of
Selector.Selections is a direct result of the number of select lines. The formula is as follows:

# of selections = 2
n
where n is the number of select lines.
