Setting up a couple of feedback loops

11 years 9 months ago #29527127 by birddawg
Hello,and thanks for reading. I have a mdc2250 controlling a couple of motors via a 2 channel Futaba transmitter/receiver. The transmitter is a surface controller meaning it has a trigger throttle brake control and steering wheel control. Channel 1 is the steering control reading an quadrature encoder that outputs 360 pulses per revolution. When I turn the wheel on the controller, the motor turns. What I would like is for the motor to return back its original position.
The second motor uses a feedback potentiometer but but the motor only rotates about 270 degrees from min to max, so when I release the trigger trottle control I would like for it to return to the center or 135 degrees.
How do I do this?
