DSE & Marv
I installed a vfd today on machine in album link. Will have pics tomorrow. All works great but I am using vfd at fixed 60 HZ frequency and varispeed sheave drive. I no longer need rotophase. 220 single phase in. 5 hp vfd.
One critical point. Do not design system that utilizes any power from vfd for control of switching device. This includes relays, holding coils, solenoids. Today I initially ran vfd output power thru motor starter. Burned up reverse coil in about 2 minutes.
