Scaling GE PME PID output

Hi, I've got a PID block in my RX3i program wherein the setpoint is 390, my feedback is 200, and the CV is the difference, 190. When I change PV manually, my CV will always be the difference between the PV and CV.

Do I need to scale the PID output to 0-32000 to control my VFD? What am I missing here?
