Need Help!- Water cooled spindle 2.2kW settings

[lolos1979]

Hi
Can You help setup my water cooled spindle 2.2kW.
I have got inverter
ABB ACS 100 ACS101-4K1-1 2.2kw 230v 1to3ph https://www.inverterdrive.com/group/...V/default.aspx

Spindle
1) Spec:φ80*205 mm (Diameter:80mm x Length:205mm)
2) Power: 2.2 KW
3) Voltage: 220V
4) Frequency: 100- 400 Hz
5) Current: 8.5 A
6) Speed: 8000-24000 R/min
7) Water Cooling

This inverer has 250Hz max. Can I connect this spindle with him? (lower speed)
RPM on inverter is only 3600 so How Can I get 24000RPM?

can you help me to setup parameters for this spindle on inverter.

Hi Pawel,

For 2.2 Kw spindle to run at 24000 rpm you will need 400 hz, with 300 hz you can go upto 18000 rpm, which would be suitable for normal mode of operations on wood. But i prefer you to go for delta vfd with 400 hz to attain maximum speed. What kind of spindle control are you using to explain the setup on the vfd.

At this time I have to use this inverter https://www.inverterdrive.com/file/A...l/default.aspx
I think that speed will be enought for me.
Spindle I bought from solar.jean http://cgi.ebay.co.uk/ws/eBayISAPI.d...=STRK:MEWNX:IT
On a inverter Max RPM is only 3600 rpm, Can u tell me how I should set 18000RPM.
I dont know really how to setup inverter to control spindle?
cheers

Have you set the vfd group 2 settings.?

They should be set something like this
201=220
202=50
203=9.5
204=3600
205=8.5
206=400
207=100

I,m not too clear on 203 i think it's used with another setting 502 to monitor thermal protection and needs to be set slightly higher than the max current 205 so if the motor draws more than this amount it shuts down.?

Hope this helps.

Just realised the vfd wont probably let you set 206 to 400 and it's max will be 300. This will just mean that the max speed will be 18000rpm

It doesn't work properly. On inverter's screen AL10 "overcurrent controller active"
Spindle is working but very slow on screen is 2.7Hz frequency and current 9.2A.
My setting:
101 - 108Hz
201 - 220v
202 - 50Hz
203 - 9A
204 - 3600rpm
205 - 8.5A
206 - 300Hz
207 - 100Hz
208 - 2
209 - 0
301 - 1
302 - 0
303 - 5s
304 - 5s
305 - 1
306 - 10
307 -0
308 -1
401 - 0
402 - 100
403 - 100
404 - 300
405 - 1
406 - 5
502 - 300

I conected pot 4.7k ohm but doesn't work.
You have any ideas why?

[lolos1979]

I change parametrs like this:
202 - 300Hz
206 - 50Hz
207 - 50Hz
306 - 0
403 - 0
404 - 50
Is working no errors but I cannot go to fast.
For what is 306 parametr?

[hemsworthlad]

Try changing 206 to =300 this is limiting the speed to 3000rpm or 50hz.
Then i think you'll find youcan turn the Freq upon the control panel to a max 300hz or 18000rpm.

[lolos1979]

If I reduce the output frequency to 75 hz the inverter runs ok. If is more I have the overcurrent fault. Can I do enythink to set higher speed?

[lolos1979]

I have got 74Hz and current is 7.9A, is it correct ? 100Hz and current is 9A. Doesn't matter what will be setup (250 Hz) I have got AL10 "overcurrent controller active". Can I drop down current ?
