∆Y = 360/ R*(1-1/ Vc)
Calculate constant
speed area
Ynew = Y-∆Y
0 ≦ P5-94 ≦ Ynew
Select new constant
speed area
Ynew < Y
∆Y = Y - Ynew
0 ≦ P5-94 ≦ Ynew
Calculate Vc
Vc = 360/ (360 - ∆Y*R)
Renew the waiting zone
P5-93.L = Wnew
= (Wd+∆Y) /2,
Covert to Hex.
Calculate P5-95 & P5-96.
P5-95.H = A*C, (Hex.)
P5-95.L = B, (Hex.)
P5-96 = 1000000*R*Vc
P5-97 = 7
