/* 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".
