I'm about to hook up my UC300ETH to an IDC16 breakout board to gain access to the analog inputs. My intention is to use PWM from the UCBB to the VFD to control my spindle's rpms but to have an override potentiometer on the analog pins on the IDC16 port.

On page 19 on the UC300ETH manual it says "The board also has an IDC16 analog I/O port with 2 analog inputs and 2 analog 0-10V outputs" yet on page 21 it doesn't mention the 10v, it only mentions 12v outputs, ground and the analog inputs and outputs. I'm assuming the analog inputs and outputs are running at 10v, am I correct?

As I'm ordering extra bits for this control box I'm after ordering a set of potentiometers to adjust both feeds and spindle rpms yet I'm not sure what resistance the potentiometers should be. Should they be 1K, 5K, 10K or does it not matter? Which pins do I connect each potentiometer up to?

Any help would be greatly appreciated.
