Activation & control of motor potentiometer
When
bInAct
is set to FALSE, the motor potentiometer is activated.
The currently active function depends on the current output signal
nOut_a
, the limit
values set and the control signals at
bUp
and
bDown
.
When the
nOut_a
output signal is outside the limits set, the output signal runs to the
next limit with the Ti times set. This process is independent of the control signals at
bUp
and
bDown
.
When the
nOut_a
output signal is inside the limits set, the output signal changes
according to the control signals at
bUp
and
bDown
.
