L6470 int_speed limitation - not compatible with my motor

Hi,
I'm exploring the EVAL6470H with my stepper motor.
according to the motor electrical parameters, the INT_SPEED should be around 2000 steps/s. The problem is that the L6470 has a maximal limitation of 976 steps/s for this parameter.
So if I want my application to work at 6000 steps/s, I cannot get a steady current while accelerating to that point (I can, though, "trick" the parameters so I would get the wanted current at 6000 steps/s).
Why do you limit the INT_SPEED parameter so low, and do you have a workaround solution for me, or is it impossible to use this motion control with my motor?

Thank you.
