Agitation Cycle

During agitation, the motor switched between the 250 rpm and -250 rpm setpoints 20 times. The results, shown in Figure 5-2, demonstrate that InstaSPIN-MOTION more closely matched the reference profile. Additionally, the maximum error for PI was 91 rpm (341 - 250 = 91 rpm); whereas, the maximum error for SpinTAC was 30 rpm (280 - 250 = 30 rpm).
