Function block instantiation (same instance)
The figure below illustrates how different instances are instantiated. Each in‐
stance has its own status that is visible via the "InVelocity" outputs, etc.

Axis addressing
General information
The function blocks for motion commanding, parameter access and generat‐
ing diagnostic messages are mostly axis-related functions. This is why the
target axis has to be transmitted to the function block as information. For this
purpose, PLCopen has defined an input/output called "Axis" ("AXIS_REF" da‐
ta type). In addition to function blocks for discrete positioning and infinite trav‐
el, there are motion function blocks for synchronous running (synchronous
motion, cam control, motion profile) of a slave axis with a master axis. In ad‐
dition to the slave axis, which in this case is the target axis of these motion
function blocks, the master axis is transmitted to the function block as anoth‐
er axis reference.
