Hello,:
I´m working in the position control of an antenna. A feedback pot (multiturn) will be linked to the antenna rotor. My question is how could two single turn pots,
be wired to the feedback pot in order to get a variable range of end stops.(min and max positions)
Thanks for your help

Yes,that´s exactly what I need..
I just need to think on how to translate this circuit into wiring my multiturn feedback pot with other two single turn pots that set the voltage limits,
and take advantage of the output to inhibit power to the motor, but
since the motor driver has an inhibit input,this wouldn´t be a problem.
I will appreciate any help with the 3 pots thing before I see smoke.
Thank you!
