I have 3 machines equipped with 30 hp AC Mtrs and VFDs. (2 mitsubishi and 1 reliance)
machine 47 is set at 120 hertz and runs at 61 hz with a draw of 17 amps while running product at 1800 fpm
machine 48 is set at 60 hertz, runs with reostat maxed, draws 16.9 amps @ a speed of 1830 fpm
machine 49 is set at 70 hz (reliance) with a similiar amp draw at approx 1800 fpm.
I am trying to gain a 10% increase in speed (approx 2000 fpm).
What are the risks v. rewards in running this way?
Machines are run 24/5.
Looking for advice, opinions, experience.........
