Hi,
Advice of the day: don't wait 3 months before testing your fresh received toy...

So disappointed.

Have you set the parameters in the VFDQuote:

Think I might be buying another from the same place and sending the old one back for a refundQuote:

I hope return address is the same as sending address (deuchland). Shipping cost could be a pita :mask:
This advice goes for anything related to CNC, esp electronics. This is the biggest mistake new builders make next to buying stepper kits.Quote:

Very sorry to read about your problems.
Clearly the ideal solution is replacement by the supplier or manufacturer. If you bought it within the EU you should have some protection (unlike our pommie friends since Friday :excitement:) and it may be worth checking if your method of purchase offers any protection or insurance.
If they refuse to help you then there may be people on this site with experience of dismantling and repairing these spindles who can advise you. It sounds like a bearing problem which is something you may be able to repair yourself with the right help.
Thanks a lot Kitwn, you're right, speaking with my seller makes me understand than it will be a DIY story...
Well, little humor story just for fun:
Just finished my CNC and started the spindle; this one makes a very bad bearing noise. I can upload a video for you. Very disappointed...
Best regards

Dear friend,
don't worry,our engineer tell us ,that is no problem, and he said: when the spindle bearing in the high-speed operation, the start state is unstable, may be possible to produce a variety of noise, the noise is the product in the transport process in the accumulation of grease caused by the side,until the grease dispersed after the spindle no such, you can use it ,
Thanks
Kind regards
Cher ami,
Ne vous inquiétez pas, notre ingénieur nous dit, ce n'est pas un problème, et il a dit: lorsque le roulement de la broche dans l'opération à grande vitesse, l'état de démarrage est instable, peut être possible de produire une variété de bruit, Le bruit est le produit dans le processus de transport dans l'accumulation de graisse causée par le côté, jusqu'à ce que la graisse se dissipe après la broche, vous pouvez l'utiliser,
Merci
Cordialement

Dear friend,
I don't think, it's a grinding noise, when you turn the spindle by hand you can hear a grinding noise. Even when you run it at 6000rpm. Do you have a mail address to upload you a video?
Thanks by advance
31/01 09:21
I'll upload the video on youtube and send you the link later.Best regards.

Dear friend,
many thanks for your buying,
pls follow this information :VFD input R,S,T port,any two ports connecting mains 220 V/AC and on the spindle motor connerter 1,2,3, connection to on the inverter :U,V,W, the mean is 1=U,2=V,3=W, 4 is blank, can't connection to GND, The minimum speed of the spindle should not be less than 9000rpm .and the VFD don't need any setting, that will be to work,
if you need any help,pls let me know,
Kind regards
Cher ami,
Merci beaucoup pour votre achat,
Veuillez suivre ces informations: entrée VFD R, S, port T, tous les deux ports connectant le secteur 220 V/AC et sur le connecteur de moteur de broche 1,2, 3, connexion sur l'onduleur: u, V, W, la moyenne est 1 = U, 2 = V, 3 = W, 4 est vide, ne peut pas se connecter à GND, la vitesse minimale de la broche ne devrait pas être inférieure à 9000 tr/min. Et le VFD n'a pas besoin de réglage, ce sera pour fonctionner,
Si vous avez besoin d'aide, veuillez me le faire savoir,
Cordialement
pls notice The minimum speed of the spindle should not be less than 9000rpm
Veuillez noter que la vitesse minimale de la broche ne doit pas être inférieure à 9000 tr/min

Dear friend, https://youtu.be/pfNIaMwcSyo Just checked of course, my wiring is ok. Each minute of running becomes worst and worst. Even the speed is not stable, a faulty bearing I think.It's clear for me, this one is defective...
Best regards.

Dear P....e, Confirmed through numerous forums as cnczone and mycncuk; is there any warranty?
Best regards

The spindle motor no any problem, i don't understand, , what you need warranty ?

so, What is my problem?
you don't have any problem of your motor, you can use it
Vous n'avez pas de problème de votre moteur, vous pouvez l'utiliser
!!!!!!! It spins, so it works!!!!
Oh, you just need to translate the noise into Chinese so that they can understand it!
For sure, perhaps it's just out of tune :listening_headphone:
Mandarin chinese 它使他妈的他妈的噪音 translated roughly 'it makes f*cking grinding noise'.

It sounds like they try to play stupid and hope you loose interest.
I must say i have had good service when i had a problem with my bearing blocks.
Must be said i also announced me being on this forum.
Grtz Bert.

Thank you all for your involvement, the fact that it's one of the bigger seller disappointed me. I had a very good experience with the BST Automation after sale service and thought it will be the same... Thanks again. News from my old friend, just one sentence: "The sound of grease".
The sound of 'missing' grease for me...:whistle:
Attachment 27374
Some news: solded as a 4 bearings unit, well well well.
Yeah. What you're missing is that there's probably only four ball bearings in that!
Yes, four square balls .:tennis:
Just listened to the video and I have heard people talk about the settling of grease in bearings (clough42 channel where he showed a very nice spindle with PDB made in the US that had a small amount of chatter). So my own view is that it can be a cause but this sounds too loud.
My bet would be the bearings are skipping around as the noise is quite loud. Are the bearings a press or good fit on the spindle shaft and housing? Wonder if they are machined out of spec?
Do you have tools to measure the fits ?
If the bearings spin nicely in your hand try loctiting them place if you are looking to try and repair it yourself.
I've been looking for the difinitive "How to dissassemble, re-grease and reassemble your 2.2Kw water cooled spindle without breaking it" thread but haven't found it. I'm sure a list of key pointers to what you must and must not do and what tools you must have before you begin would be much appreciated by many readers contemplating a check of their bearings. Is this something the pro users do regularly?
Spindle: 1 Me: 0
It's a pita because you must fabricate your tools, and even they easily breaks (only 2.5mm pins...). You must heat at least 3 minutes in full power with your heater before trying unscrew this "#&@% full of holes". I enlarged them to 5mm,. But after this first victory, there's another flange. End of the story for me.

The 6002 bearing must have the large side pointed to the top. It's not a radial bearing.
Hi Jonathan,
I have just put together WorkBee 1000 x 1000 mm CNC machine. I am totally intimidated by the electronics. I purchased this machine from a firm in China and the directions for electronics are either nonexistent or (for me) undecipherable. Can you put me in touch with anyone who can walk me through this electronic challenge?
I have a Huanyang GDZ-80-1.5 11V 1.5Kw 5A 400Hz spindle, an HY01D511B , an LRS-350-24, a UNO cardstepper card.
Thank you for your time.
I'm using a 400Hz 220V 24,000RPM Spindle motor from Vevor
Can anyone remind me of the Mitsubishi FR-D720 parameter settings for this motor please.
