Since I am using the same spindle and VFD as the OP (2.2Kw 220v 400Hz Water Cooled spindle and 3.0Kw VFD) I am assuming that this is the correct parameter list. I noticed that PD006 @190 and PD009 @ 102 appear to be much larger numbers than in previous posts from you over the years. Just wanted to make sure these weren't typos.
Just a FYI that I purchased the spindle from Amazon at the Huanyang factory store and the ground pin was actually hooked up direct from the factory.
Thanks for the help
I have my spindle and VFD operating using the parameters in the previous post. The one thing that is concerning is a high pitched warbling sound the spindle makes until the spindle warms up in about 15 minutes to a half hour. After that the noise goes away and it sounds normal. Sometimes I can make the noise go away if I stop the spindle then restart it. I have ran the spindle at varying speeds for a few hours to break the bearings in but once the spindle cools down the noise returns until the spindle warms up again.Is this something that will go away in time or should I exchange it.I have a few more weeks before the 30 day return period on Amazon. The link below is a short video of the noise.

I made the above changes and the spindle runs and cuts fine however the noise is still intermittently there. Yesterday the spindle was perfectly quite thru it's entire RPM range even when cold but today the noise returned and won't go away no matter how long I run it. I am debating ordering another spindle from Amazon to see if I have a bad spindle.
Are you using a EMI Rated Power Filter on the input power and is the Grounding for the spindle correct, Spindle 4th Pin to VFD Drive Shielding also Grounded at Both Ends, do you have a good 240v supply to the VFD Drive Power connected to R and T and Ground Terminals connected
Try PD41=10

The only thing I don't have is the input power filter. I have a 14ga 4 wire shielded servo rated cable with the shield grounded at both ends.The 4th pin on the spindle is grounded to the case. I have a chassis ground from the Z slide back to the central star ground.The 240vac supply is wired as described above.The video was taken with the carrier frequency PD41 already set to 10.Changing PD41 to 10 didn't have much effect on the strange sound but it did make the spindle noticeable quieter.
I have a photo tach, works on light bouncing or reflected back from either a white mark or reflective tape on the target. I used it to calibrate my speed control pot I have mounted remotely
on my CNC machine. I think I got it from Harbor Freight a few years ago. Its pretty accurate as I have checked it again a known RPM. Its possible your motor speed is varying and the read out is not
showing it because its mechanical.
