L6470 MIN_SPEED register

Hi,

Description of this Register is confusing me all the way.
It is written:
"When the LSPD_OPT bit is set high, the low speed optimization feature is enabled and the
MIN_SPEED value indicates the speed threshold below which the compensation works. In
this case the minimum speed of the speed profile is set to zero.
"

So, what i did is set the MIN_SPEED at zerro and set the LSPD_OPT high.
But somehow i dont see any difference.

I am running at low Speed and low voltage.
The Speed where i want that compesation will be active is 2,228 steps/sec

On one Hand it is written that min_speed is a treshold below which the compesation works and at the other Hand ist written that Setting LSPD_OPT hight will set this value to zerro.

So which Value schould I set at MIN_SPEED so that my stepper can run at 2,228 steps/sec and have the compensation working?

Regards
Igor
