I have aquired a few of these spindles and I would like to hook one of these up to my own CNC.

In order to do this I need a VFD for this, and I have got 2 different ones to try out.

I have a Control techniques Unidrive UNI2402 and a Hitachi WJ200-150HFE drive to play with.

I'm trying to test it out on the bench, with a speed potmeter attached, to the Hitachi drive, and it keeps going into overload.

I have set these paramters for now

A001 - 00
A002 - 2
A003 - 50Hz
A004 - 400Hz
A044 - 1
A082 - 380v
B012 - 16A
H003 - 7,5kw (goes in speciel increments so 7,5kw was the closest)
H004 - 2 poles

Am I missing something??

The Unidrive VFD was the one that was placd on the Biesse machine the spindles came of, I cannot get into controlling the speed manually with a Speedpot..

I have tried most anything already, and I'm looking for some serious help now.

So if anyone is really good at the one or the other, then please help me out.
