VFD/motor setup issues - no torque, whining

You can hear it in the video, it's just whining like crazy. I let it go quite a ways until I was certain the motor would pop, but it never has any torque.
HY0D223B w/ 1.5HP 3PH motor, 3450 RPM

I've double checked all the inputs and outputs, and am starting to question the motor itself.
I've set PD141,142,143,144,176
 
I'd also run through the rest of the parameters and make sure everything is set properly. MOST of them will remain at their factory defaults, but there are a couple up front that may need adjusted IIRC.
 
VFD manual and motor data plate photos are a minimum

Do you have known good motor and vfd ? swap each out with the other
 
My guess is that your motor is wired incorrectly. What voltage are your running? I assume 230V? How are your wires connected to the VFD? WYE connection I'm guessing?

If so-
Wires 4-5-6 tie together
7&1 tied to one wire from the VFD
8&2 tied to one wire from the VFD
9&3 tied to one wire from the VFD
Make sure it's grounded also.

If this is correct I'd try another motor.
 
Yes, I have everything set according to the manual, 240V single phase, both hot wires to RS and ground to E, UVW out to the motor. Just rewired the motor 1/7, 2/8, 3/9 with fresh crimps. I'll have to check with a different motor tomorrow afternoon.
 
Definitely not a motor issue, my nearly identical Baldor does the same thing. I know this is going to be something simple, just not sure what.
Manual:
http://www.jinlantrade.com/ebay/invertermanual.pdf

First, I followed the inital setup:
Firstly, adjust the PD013 to 8 (set the setting to factory setting)
Secondly, adjust the PD005 to 400
Thirdly, adjust the PD004 to 400
Finally, adjust the PD003 to 400
Finally, adjust the PD144 to 3450 (RPM)

Then, I checked all these and found them to be satisfactory:
PD000=0 for Parameter unlock ( 1 ) for Parameter Lock
PD001=0 (1 For Remote Control)
PD002=0
PD003=400
PD004=400
PD005=400
PD007=20
PD008=220
PD011=120 (Minimum Setting 120)
PD009=15
PD010=8

PD014 Accel=12 ( Adjust to suit)
PD015 Deccl=12 (Adjust to suit) ( PD15 is ignored IF PD26=1 Then the Spindle will Coast to a Stop)
PD141=240 ( Motor Rated Voltage )
PD142=4.6 ( Motor Max Amps) (Set for your motor Amp Rating 2.2Kw Spindle 9 amp Max)
(Set for your motor Amp Rating 1.5Kw Spindle 7 amp Max)
PD143=2 ( Motor Number of Poles)
PD144=3450 (Max Motor RPM) =3,000= (24,000)

I do not understand how it is possible to stop with hand motor that rotates at high speed ?? Just rotor weight gives high torque at that speed , even after power is off ?? Are you sure that drive wheel not slip on motor shafts ?

Set P003 and P004 to 60.00 (assuming you live in the US, 50Hz if elsewhere; it should match your motor's nameplate). P005 can stay at 400 if you wish.

That's likely your issue.
 
I'd also set PD005 to 120 (or 90) depending on how much you wish to overspeed your motor. PD003 and PD004 are for the operating freq of the power line, which as Drew said above.
 
PD 3,4,5 & 7 are all set for a 400 Hz high-speed spindle motor (24000 RPM). Set them to suit the rating plate values on your motor and all should be well.
 
Also, if you are using a speed control pot, you'll need to set PD 72 & 73 to suit. There's something odd about them: I can't remember whether the parameters or just the descriptions in the manual were the wrong way round.

What made you choose this VFD ?

Was it "cheap on ebay" ?

How much was it?

Yep, that is one of the $110 to $120 shipped VFD's on ebay that work so good. Just a bit of setting up, and there are pretty good manuals around to help with setup. I've helped setup several of them, and have personal experience with a couple (3?) and they do a good job. When used for a grinder they need to be installed in a dustproof box, OR (as I've done) put a filter over the air inlet to keep steel dust from insides.

Thanks, there's definitely less whining and a lot more torque. Count, I really don't remember on this VFD, but they are around $100 and it will handle up to 3HP so probably price. It's configurable out the wazoo, which isn't a bad thing once you get it figured out. Also, it can be remotely switched for stop/forward, which I like. Yes, I plan to build a filter box for it.

Strange,I would have thought setting PD176 to 1(60 HZ) would have set everything to 60HZ. Then again, like Tim pointed out, most message boards discuss this VFD with a 24k spindle instead of a 3450 Baldor.
 
I was curious about your drive, so I went on the webz and looked around, someone said this;

random internet said:
Note: you should set PD013, PD005, PD004,PD003, PD144 in order. It mean you should firstly set PD013, then PD005, then PD004, then set PD003, finally set PD144.
Note: after you set the all above parameter, then please recheck the PD005, PD004, PD003 value is 400 or not to confirmed that you already set it. (note: please do not check the PD013, or all the setting will go to factory setting)

Yes, that's correct IF you are using a 24000 RPM spindle that runs at 400 Hz. That comment was taken from a machining forum where they were setting up a CNC mill which runs at much higher RPM. It works great if you set PD003 and PD004 to 60, if you have a 60 Hz motor instead.

It was the specific order of operation I was wondering about. Since you listed your steps in numerical order. Quite a strange post about the drive you have. I've never seen non-sequential out of order setting requirements before.
