Activate & Control Motor Potentiometer - Lenze 8400 StateLine C Reference Manual

16.1.23.1 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.
