b. The length of bobbin is changed and the width of tape remains.
See Figure 3.2.21. Assume the length of bobbin is changed from 190mm to 150mm and the
width of tape and the interval remain at 15mm and 0.2mm respectively.

∆Y, adjust the parameter of E-cam distance:
150mm – 15.2mm=134.8 mm;
134.8mm / 5 (mm/rev) = 26.96 rev, the cycle the ball screw travels;
26.96 * 2 = 53.92 rev, converse to motor by E-cam;
PR#2: P5-19=53.92.
∆X, adjust the pulse number sent by master axis:
150mm / (15mm + 0.2mm) =9.8684 cycles;
(9.8684-1)cycle * 14400 (pulse/cycle) =127704 pulse;
PR#4: P5-84=127704/2=63852;
PR#5: P5-89=63852;
PR#11: P5-84=127704;
PR#12: P5-89=127704.
