Im in the middle of rebuilding a southbend lathe. I purchased a new invertor class 3 phase, 2hp motor. I also purchased a hitachi wj200 3hp VFD. I have been trying to find out a way to quiet the loud pitched whine that you hear caused by the pwm. I read everywhere and was told that a load reactor would quiet the system down. I purchased a load reactor and it makes the noise worse.....
I have everything grounded good and am using good "VFD" cable that is double shielded.
any suggestions?
Thanks
