[参考译文] MCT8329A：电机锁定和同步丢失故障有时会通过 I2C 清除#39；t CLEAR

工具与软件：

尊敬的德州仪器(TI)支持团队：

我遇到了 MCT8329A 高速无传感器梯形控制三相 BLDC 栅极驱动器在基于评估板原理图的定制电路板上的问题。 设置详细信息如下：

1. 驱动器配置为仅在开环模式下运行电机。
2. I2C 用于与 IC 连接。
3. 最后列出了完整的电机配置设置

问题描述： 当电机运行并且我命令电机转速为零时、控制器故障寄存器会报告故障代码0x80500000。 此故障代码对应于以下故障：

• 检测到控制器故障情况
• 检测到 SYNC 丢失故障
• 检测到电机锁定故障
• STL 失败(尽管我们禁用了 STL)
• 应用程序复位失败

通常、我可以通过写入 CLR_FLT 寄存器来清除故障。 但是、在某些情况下、此方法不起作用、并且故障仍然未清除。 在这些情况下、电机停止旋转、但故障仍然存在、表示检测到同步丢失和电机锁定。 我在 nFault 引脚上有一个示波器探头、即使通过 I2C 将 RESET 置为有效、该引脚也一直处于低电平。 在这种情况下、我唯一能够清除故障的方法是对电路板进行下电上电、这不是可接受的解决方案。

请您协助解决此问题。 如果您需要任何其他信息、或者我可以采取任何故障排除步骤来解决此问题、请告诉我。

感谢您的支持。

此致、
