FOC开环模式来调试硬件出现反向

你好，


我目前正在使用开环模式来调试我的硬件，当前读数等。

我通过反复试验找到了V / f曲线的偏移和斜率的最佳值，这样电机就可以在整个速度范围内工作。

但是，当我通过MCI_ExecSpeedRamp（MCI，Vel，time）设置负速度时，电机的行为与正方向的行为不同。

如果我用默认值替换偏移和斜率值，则电机在两个方向上的行为相似。

我是否错过了使用V / f曲线使Open循环工作的一些步骤？

关于另一个话题：
如何获取FOC SDK的机密分发？
我打电话给ST的销售，这导致我去当地的经销商。
我联系过我国的几家经销商。一对夫妇没有帮助，其他人不知道我在寻找什么。其他几个人说他们会将我的请求重定向到ST。
到目前为止，我找不到任何可以帮助我的人。

我如何联系ST以帮助我获取SDK？

最好的祝福

Hello,


I'm currently using Open loop mode for debugging my hardware, current readings and such.

I have found by trial and error the best values for the offset and slope of the V/f curve, such that the motors work on the full range of speeds.

However, when I set negative velocities through MCI_ExecSpeedRamp(MCI, Vel, time), the motors do not behave the same as in the positive direction.

If I replace my offset and slope values by the default ones, the motors behave similarly in both directions.

Am I missing some step to make Open loop work with my V/f curve?

On another topic:
How can I obtain the confidential distribution of FOC SDK?
I've phoned ST's sales, which directed me to my local distributors.  
I've contacted several distributors on my country. A couple were unhelpful, others had no idea what I was looking for. A couple others said they would redirect my request to ST.
So far I was not able to find anyone who could help me.

How can I contact in ST to help me obtain the SDK?

Best regards
