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.

Queues View

Many applications require the ability to store data in a temporary memory location as the data comes in. The user then has

access to the data for use in a program or other operation. The FM-3/4 module and Epsilon EP-P drive use an object called a

queue to store data in this way. The queue is a first-in-first-out (FIFO) type memory device. In other words, the first piece of

data put into the queue is the first piece of data to come out of the queue. The user has complete control over what data is

stored in the queue, and when to put data into the queue, as well as when to remove it from the queue.
