这是lab11e中的一段程序，上面是变量地址的计算，目前是正转，我修改了gHall_State_delta = gHall_PwmIndex[gHall_PrevState] – gHall_PwmIndex[gHall_State];按照程序可以实现反转，但是还是正转，为什么呢？

在目前gMotorVars.SpeedRef_krpm为正的时候，运行比较平稳，但修改为负数，会出现过流现象，这是为什么呢？

K Mr：电机速度的参数修改为负数即可实现电机反转，但是出现过流是不是硬件上存在问题？

过流有可能是hall角度估算错误引起的。
另外，建议你这边整理一下问题后在英文版的E2E上发帖咨询一下。那边有专门针对电机控制的工程师可以为你辅导。

使能了PWM就好了，之前的程序禁用PWM
