RS has to be adjusted so that the applied voltage
VM is suitable for a given motor, the speed is then
linearly adjustable varing RB.
The value RT is calculated so that
RT (max.) > K(min.) * RM (min.)
if RT (max.) > K * RM, instability may occur.
The values of C15 (4.7
F typ.) and C14 (1F
typ.) depend on the type of motor used. C15 ad-
justs WOW and flutter of the system. C14 sup-
presses motor spikes.
