How to calculate the frequency of each segment and the number of output pulse:
1. Destination: Draw a clockwise arc to (50000,50000) with 10 segments as shown as follows:
(0,0)
(0,Ry)
(Rx,0)
(x10,y10)
(x1,y1)
(x2,y2)
(x3,y3)
(x4,y4)
(x5,y5)
(x6,y6)
(x7,y7)
(x8,y8)
(x9,y9)

Y axis
2. Rx is a target value of X axis; Ry is a target value of Y axis; N is the number of segments;
π
=3.1416
Step 1: Calculate the position of each segment
X axis Æ
x1 = Rx – Rx*sin
[
(N–1)*
π
/(2*N)
]
x2 = Rx – Rx*sin
[
(N–2)*
π
/(2*N)
]
