800w spindle - noise & controlling remotely

[Boyan Silyavski]

I guess my quickest way forward here is to buy another 800w spindle & hook that up ...if it works, then my old spindle was faulty (which I think it is), if it still trips then I can sell it on!

Some of these water cooled spindle adverts tout themselves as 'four bearing' ...do I need this if I'm only milling pcbs & acrlyic? (in other words what does four bearings bring to the party - they're about £30 more vs the cheapest 800w water cooled spindles on Ebay)

I believe all are 4 bearing, forget the crap the sellers are telling.

I decided to read a bit again the manual, to check what the problem could be.

Lets troubleshoot a bit:

1. check if by error you programmed 230v 60HZ instead of 50HZ

2. check if you properly established accelaration and deccelaration time , i use 10 seconds

3. check 5.4 of the manual , setting your motor
AU2 should be set to 0 instead

As far as i remember, some motors had problems with the auto tuning, so don't use it anywhere for now

uL: Base frequency 1 (rated frequency) set to 400
uLu: Base frequency voltage 1 (rated voltage) set to 230
F405: Motor rated capacity set to 0.75
F415: Motor rated current set to 3.4
F417: Motor rated speed 1410 / I am lost why i set it like this/

4. 5.9
UL=400
LL=0.0

5. 5.11
Pt=0

make sure F416 is set to 60


In general avoid the stuff like boosting and so untill you make it work.

if you doubt a particular parameter just drop a line here, i will check and report

You did not mention what the trip says exactly?
