+/* LA: Theory of Operation.
+// ========================
+//
+// once Encoder/Axis is Homed and Cycle Condition's Sussist, AC_Pos_Positioning is alloweed to take Control.
+// This is done by keeping "STW1_Control" true.
+//
+// if Servolock is off, The Axis is then Set to "Free Wheel Axis"
+// Otherwise, the System Keeps Actual Position (ServLock works inside the Tolerance window, if there's move),
+// or a New Move is Started if Target is != Actual Position.
+//
+// if ServoLock is true and movement is alloweed, after the positioning will have Actual = Target, Tolerance
+// flags active and a constant control to keep this.
+//
+// if "Axis" is Not Homed, All Positioning Flag(s) are kept clear
+*/
+
+/* LA: Verifica di coerenza del Profilo:
+// =================================
+//
+// Se Lo spazio di Accelerazione sommato a quello di Decelerazione, ad INIZIO MOVIMENTO, supera la distanza (in Modulo) da percorrere,
+// allora il profilo và corretto (Non è più un trapezio ma diventa un triangolo).
+//
+// Per correggere il profilo occorre:
+//
+// 1) Calcolare le equazioni di entrambe le rette (Accelerazione e Decelerazione)
+// 2) Ricavare il punto di intersezione delle due rette (La cui "Ascissa" sarà la velocità massima raggiungibile, l'"Ordinata" il punto a cui la raggiungerà)
+// 3) Sostituire all'Accelerazione il valore "Ordinata"- Punto di Partenza (Verificando il segno dell'operazione in base al verso)
+// 4) Sostituire alla Decelerazione il valore Destinazione - "Ordinata" (Verificando il segno dell'operazione in base al verso)
+// 5) Sostituire alla Velocità di Movimento l'"Ascissa"
+//
+// Avendo già le equazioni di RettaxAcc e RettaxDec:
+// =================================================
+//
+// RettaxAcc: Y = (m * X)+ q
+// RettaxDec: Y = (n * X)+ t
+//
+// Il punto X a cui le Y si equivalgono è X = (t- q)/ (m- n), la Y è ricavabile, indifferentemente, da entrambe le equazioni al punto X.
+// Questo permetterà la corretta esecuzione del "Triangolo", col vertice alla "velocità massima calcolata" e rampe teoriche equivalenti a quelle programmate.
+//
+// ****
+// ****
+// ****
+// ****
+//
+// Se non ho il "tempo" per calcolarlo uso un trucco:
+// Se il profilo è da correggere (Acc+ Dec > Distance) carico in ActualSpeed la Velocità di Servolock e lascio che l'asse si muova alla "Minima".
