atv28 to atv320
using an atv28 3 wire with a potentiometer to set our speed and maintaining speed with an input 4-20ma signal using AIC-PIA on a center winding machine. I am trying to have the atv320 do the same thing.
With the potentiometer i turn till speed is running at 136' per minute, as the roll increases in diameter the web is speeding up, with a frequency generator the ma's increase and slow the machine down to maintain the speed of 136' per minute.
