Function
A function calculates a result according to the current value of its inputs.
A function has no internal data and is not linked to declared instances. - Returns the status of the internal generator of the axis.
The status of the Axis generator: acceleration A change in velocity over time.
Because velocity is a vector, it can change in two ways: a change in magnitude and/or a change in direction.
In one dimension, acceleration is the rate at which something speeds up or slows down.
However, more generally, acceleration is a vector quantity expressing the change with time of the velocity both in magnitude and in direction.

This function or function block
A function block groups an algorithm and a set of private data.
It has inputs and outputs. returns cached data.
