Coils,

Within the drive parameters you are going to need to do a hertz to rpm conversion. This reason is due to a standard AC motor runs at 1800 rpms @ 60 Hz. I am running a 24000 rpm spindle @ 400 Hz. If you have CT Soft on your computer you can easily change the parameters, and or directly on drive. These are the parameters you need to change.

par. 00.07 change from 1800 to 7200
par. 00.08 change from 230 to 220
par. 00.39 change from 50 to 400hz
par. 00.40 change from auto poles to 2 pole
par. 00.41 change from ur1 to fd

At all this is complete I would then power off. Let is fully power off and re-energize.
I would then recommend to purchase a tachometer and test run your spindle.
So your numbers should come in around.

400 hz =24000
300 hz=18000
200 hz=12000 etc.

Let me know what else you need. This should put you in the ball park. If not right on.

Thanks Brooks

I did install the CT Soft, but I couldn't get it to communicate with the drive, I'll see if there's a manual on the disc (yes I did the guy thing and didn't look for / at the manual yet). All I did was hooked up a network wire from the pc to the drive and messed with the program a little but that's as far as I got.
All I did so far was set a few of the parameters using the buttons on the drive itself.

I'll look into those parameters you listed, I'll just have to change the setting a little from yours since my motor is rated at something like 3360 rpm and should be around 120hz set in the drive to get 10k rpm, I've just kept the drive set to 60hz for now until I get this stuff figured out.

And yes I was planning to get one of those hand held tachometers, maybe I should do that tonight so I'll have it by the end of the week.

Sounds good I posted a couple documents for you to look at. One is the advanced user manual for SK Commander, and the other is a write up on High Speed Spindles and VFD's. Hope everything works out for you.

Note: I have never used a ethernet cable from PC to Drive. The drive RJ45 jack is Modbus RTU. I purchased the programming cable to interconnect program to drive. The parameters I gave you on last reply were all available to change directly from your keypad on drive just so you know. I like to be able to see the other parameters in drive, that is why I got the cable.
