try to follow and center about the reference voltage setting
if it is within the input common−mode voltage range of
Pin 3; Figures 4 and 5. Initially consider that the feedback
input voltage level is somewhere on the dashed line between
V
defined above and the motor will be off. Now if the reference
voltage is raised so that V
will turn−on [3] enabling Q Drive, causing Drive Output A
to sink and B to source motor current [8]. The actuator will
move in Direction B until V
Comparator B will turn−off, activating the brake enable [4]

and Q Brake [6] causing Drive Output A to go high and B to
go into a high impedance state. The inertia of the mechanical
system will drive the motor as a generator creating a positive
voltage on Pin 10 with respect to Pin 14. The servo system
can be stopped quickly, so as not to over−shoot through the
dead zone range, by braking. This is accomplished by
shorting the motor/generator terminals together. Brake
current will flow into the diode at Drive Output B, through
the internal V
transistor at Drive Output A. The end of the solid line and
