STMC Workbench欠压故障和过流故障

Ciao Christian
 
 
 如果在故障确认之后错误仍然存​​在，则这意味着微观仍然看到这些错误。
 
 您没有提到的一个修改是关闭SB16以将紧急输入连接到PI6（可能您还必须卸载默认连接到该引脚的相机模块）
 之后，您可以验证PI6上的电压是否上拉至3.3V，这将清除过流错误。 （故障确认后）
 
 Regardind的undervolatge，似乎很奇怪。
 设置到WB的阈值是125V。使用WB的“监视器”功能，您可以验证测量的总线电压（您还可以使用万用表验证测量的总线电压是否与实际总线电压一致）然后如果此值高于125V则欠压错误将消失。

If the error remains after the fault ack this mean that the micro sees these error still in place.

One modification that you don't mention is to close SB16 to connect the emergency input to PI6 (and probably you have to unmount also the camera modue that is for default connected to that pin)
After that you can verify if the voltage level on the PI6 is pullup to 3.3V and this will clear the overcurrent error. (after the Fault Ack)

Regardind the undervolatge, it seems very strange.
The threshold set into the WB is 125V. Using the ''monitor'' feature of WB you can verify the measured bus voltage (you can also verify if the measured bus voltage is coherent with the real bus voltage using a multimeter) then if this value is above the 125V the Under Voltage error shall disappear.

嗨，
 
 
谢谢，你是对的，我忘了关闭SB16。
 
问候

Hi,


Thank you, you were right,  I forgot to close SB16.
