点选 on the fly startup 后依然失败，顺风成功逆风失败，想请教这个问题该怎么解决，多谢

是否有报错，有报错按照错误代码查找问题

主要是逆风煞车没什么用，一样在逆转，自然就产生启动失败，或 speed error ，感觉没有煞车的功能，顺风跟静止启动经过调适皆可以成功，但是逆风完全失败，多谢帮忙

Workbench 上没有调适煞车力道的地方，只有时间，请问有人知道对应到代码的哪里吗 ? 多谢

workbench里面的刹车只是将MOSFET关闭，让其自由停机，这个你需要自己写刹车功能程序了

Typically, this fault message appears because there is insufficient current provided to support the required speed acceleration.


1、 Decrease the speed acceleration rate :
      Increase the “Speed ramp duration” parameter;

      Set the “Speed ramp final value” parameter to 30% of your maximum application speed.

2、Increase the start-up current :
       Increase the “Current ramp initial value” parameter;

       Increase the “Current ramp final value” parameter up to the “Nominal Current” parameter of the motor;

       Check the “Include alignment before ramp-up” box to make the start-up phase more deterministic, and follow the FAQ on "Basic parameters settings for the ramp-up"
