Having looked at the config which you attached, I am rather puzzled.
There seem to be many more files than I would expect, files named the

Hi Peter,
thanks for you reply.
Its hard to tell with motor specifications, sometimes they are RMS and
sometimes they are DC (for example lots of large BLDC motors are rated 320V
which actually means they are 220V AC motors)
I see. I'll stick with 24 V for now, the power supply is a 350 W
Hi Andy,
I decided to put the system on my desk to investigate the case, this
took a while.
How are you commutating?
The present configuration is 'qh'(use encoder input, use hall sensor
input). I didn't override the default commutation setting, so I think
its sinusoidal.

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
Hi Peter
Where did you measure the current?
I measured one phase.
(you may indeed measure 600mA in the power
leads with current limiting (7.5A) in the driver)
The 600 mA was mistake, current reaches 3.5 A actually.
If you see a red LED light on the 7I39, you have reached the current

Hi Andy
It is probably worth checking that it works properly in plain
h mode as a test that the hall pattern is correct.
I'll try.
What would be the best setting? The drivers have 3 hall sensors and a
4000 CPR encoder with index.
But the 600mA at stall looks like the real issue.
No, this

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.

Hi Andy

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
