Yaskawa V1000 - 5hp motor squeal?

[jareese]

Is there a way to “tune” it out?
I watched a video with Clough42 on U-Tube and tuning his VFD to get rid of the squeal in his motor. (6:25 in this video. Can this be done on the Yaskawa?

@mksj do you have any input on this?

220 Single Phase to VFD on L1 and L2

You need to increase the carrier frequency parameter C6-02, if you set it to 05 it should be 12.5kHz which is what I use. The noise will increase as you turn down the speed.
