Dear hinddhindsa.
Without knowing your program I can only make some guesses.
I assume you are using the analogue comparator function block A to start the motor.
Within this function block the input value I1 or I2 and the hysteresis value HY have to be
changeable and not a constant, for example by using a word value MW.
These values MW you can show on your display by using a text function D and mark them as
editable.
I propose to upload your program or at least the important part to give to you more detailed advice.
Regards
Maikky
