The timing can be divided into several parts starting from
a steady state (see Fig.5, the starting point, and Fig.10 for
the application diagram): in this state (until T
reference current is active, indicated by the dotted lines.
When the setting potentiometer is rotated (started at T
and indicated by V
higher than the reference current I
will start and the input current will decrease. At the same
time the reference current is switched to a low level.
During rotation of the motor the input current will decrease
until it becomes lower than this low reference current;

this occurs at time T
active, the motor will stop and the reference current is set
to the higher value. The brake is realized by
short-circuiting the motor. In general: this system does not
use a linear adaptation strategy but an on-off strategy.
This results in high accuracy and low noise sensitivity.
The brake is active at any time during normal operation
when the motor is not active. The polarity of the feedback
potentiometer should be such that the voltage at the slider
of the feedback potentiometer increases when OUT1 is
high and OUT2 is low.
