Epsilon EP-P Drive and FM-3/4 Module Reference Manual

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.

Selector View

The Selector view is located under I/O Setup in the Hierarchy Tree on the left of the view.

Figure 69: 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 70).

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

where n is the number of select lines.

The maximum number of select lines is eight.

Once you have determined how many select lines you want, the assignments to these Selector.Select lines must then be made

in the Assignments view.
