L6470与我的电机不兼容

嗨，

我用步进电机探索EVAL6470H。
根据电机电气参数，INT_SPEED应为2000步/ s左右。问题是L6470对此参数的最大限制为976步/秒。
因此，如果我希望我的应用程序以6000步/秒的速度工作，那么在加速到那一点时我无法获得稳定的电流（但我可以''欺骗''参数，这样我就可以获得6000步/秒的所需电流）。
为什么要将INT_SPEED参数限制得那么低，你有一个解决方案吗？或者我的电机不能使用这个运动控制？

谢谢。

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.
