number of output pulses is smaller or larger than the calculated number of output pulses
(taget number of feedbacks x percentage value/100), this can be improved by adjusting
the percentage value, acceleration/decelartion time or the target frequency.
Program Example:
1. Assume we choose X0 as the external interrupt, with I001 (rising-edge trigger) interrupt; target
number of feedbacks = 50,000; target frequency = 10KHz; Y0, Y1 (CH0) for the output pulses;
start/end frequency (D1340) = 200Hz; acceleration time (D1343) = 300ms; deceleration time
(D1348) = 600ms; percentage value (D1198) = 100; current number of output pulses (D1336,
D1337) = 0.
