I have a composite DC drive that uses two motor controllers, one
for the armature and one for field. The original input devise for the speed control was a tandem pot that is no longer available. This was unique in how it was configured. The assembly rotated 320 degrees and the first half of rotation one pot changed value linearly and then remained at the high value through the rest of the sweep. The other pot has an inverse function where the start value is high and remains high for the first half of rotation and then drops in linear fashion to full travel.
I would like to use something to recreate this relationship of value with something that can produce a 0-10 VDC signal output. Driven by a single pot variable DC 0-10 volt input. The current requirement is signal power in the low mil amp range.
Sounds easy enough? Where do I start?
