I have a problem with the AREF INPUTS on the old 454 GT Drive. I have been over the settings a thousand times in the menu's, but the Analog inputs are being held at 11ma. No change with simulator, Pressure TX, EVEN when no input is hooked up at all!
As a result the VFD runs at one speed in Auto. I can speed up and slow down the VFD in manual however. I am useing a 4-20ma singnal from a PT to control the VFD Speed. REAL SIMPLE (or it should be) Are the VFD inputs toast? Or am I missing something?
