If your VFD's whine, up the setting for carrier frequency. My 17", 7.5hp lathe ramps up to speed in 3.0.seconds on a 30a single phase breaker and runs quite with no issues.That does get annoying, so does the high pitched whine of the VFD while I still have some hearing. My new shop will have the motor in another room. Won't ever hear it.
I too am in SW Boise... pm inboundI have a 40hp and a 60hp phase converters. You guys whining about listening to a measly 7.5hp is funny.Nothing like running 5 motors for 3 CNC's.
