2.2KW water cooled spindle and Altivar 12 2.2kW 230V 1ph to 3ph

[paulus.v]

Edited: Here are the Schneider ATV12 settings for the Chinese 2.2kw water-cooled spindle:

bFr - 50 Hz
HSP - 400 Hz
nPr - 2.20 kW
nCr - 0.8 LN (8.0 A)
Allt - 10V
UnS - 220 V
FrS - 400 Hz
nSP - 24000 RPM
tFr - 400 Hz
Ctt - PErF

personal choice:
ACC - 10 s
dEC - 10 s
LSP - 1.0 Hz
rPt - LIn
nrd - yES
SFr - 16 kHz
SFt - HF2

Edit: regarding the low minimum frequency I like to have it from zero. If I need to touch the material in the old fashion, with a piece of newspaper, I feel more safe running the spindle at 1-3 Hz with almost no torque. On the other hand I managed to cut 9 holes in 20mm pinewood with this tool at 1500 rpm with 10 mm/min :)

I got everything running as it should be.

Thank you Dean and Paulus V.

Many thanks

Since my spindle cable is floating I would like some opinions about how I mount that on the router without affect the stepper lines.

Many thanks

I went for the 'safe' option of not running in the router frame at all, although I've noticed that Dean's machines tend to run the spindle cable in some energy chain back to the Y carriage so if you take the precautions you can run it on the machine frame.

Here is my very old machine but you can see the simple hook arrangement which allows the machine to move around:


BUT - if you have this sort of GX16 screw-on connector to the spindle it will work loose on the pins over time and in case you don't know you must not allow a break in the circuit when under power. It will almost certainly kill the VFD stone dead - ask me how I know! :


So you can replace the connector with a strain relief grommet (see top of spindle):


Plus solder the cables direct to the motor by removing the end cap.

Yes when done correctly using shielded cables with correct grounding precautions taken then running VFD cable loosely along side other cables isn't a problem. I do try to run some separation by placing water pipes between cables but still there are places they rub and meet which can't be avoided.

Regards the Spindle connection then I suggest making some form of bracket to help take the strain off the connector and cables. Here's how I do it.!
