10.1.1 Activate & control 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.
