What did you edit it with?
The error message is:

Which looks like the hal file is not a plain text file any more.

Having looked at the config which you attached, I am rather puzzled.

I see. I'll stick with 24 V for now, the power supply is a 350 W

The present configuration is 'qh'(use encoder input, use hall sensor

Hi,
an brief update, because my current measurement was wrong.
I now used a normal ampere meter (Flue 87V) and measured a maximum
current of 3.5 A. (I commanded the motor to a position where the phase I
observed was at maximum current under low load and than increased the
load until the motor stal
Hi Peter

The 600 mA was mistake, current reaches 3.5 A actually.

I'll try.
What would be the best setting? The drivers have 3 hall sensors and a
4000 CPR encoder with index.

qh is almost certainly the best. You could try qhi if, and only if,
you are sure of the index pulse orientation.

OK, now the jumper are moved from left to right and I reached 6 A max.

I don't know the orientation aka offset, but I tried to measure it, by
observing the index signal, the encoder counter and the hall sensors in
hal scope. I think I got it r

I would have thought so.
3hp sounds like plenty to me. My 2hp mill never slows down even with the big
cutters.
