[参考译文] MCF8315EVM：电机不会旋转、电机驱动线永远不会被驱动、如何诊断故障

您好！

感谢您发布您的问题、我今天不在工作中、明天我会给您回复。

谢谢、此致

尊敬的 John：

您能否确认是否应用了所有配置？  

您能否共享您使用过的电机数据表和 JSON 文件？

谢谢、此致

我添加了电机数据表和 json 文件

我相信我应用了足够的配置来使电机运转

尊敬的 John：

感谢您分享详细信息、我将核实这一点并进行回复。

谢谢、此致

尊敬的 John：

我查看了 JSON 文件、还想检查您使用的 GUI 和 EVM 版本。

在详细了解我的问题之前、我 想您正在使用的是 MCF8315A GUI、它不是基于新的 GUI 格式的 MOTOR Studio。

我看到 SPD_LOOP_KP、SPD_LOOP_KI 为零、这可能触发 MPET、或者速度环路的 PI 环路没有扭矩命令、不会生成任何扭矩基准。

我建议您迁移到 Motor Studio、我将共享参考 JSON 文件以运行 MPET 并对其进行测试。

您需要根据此链接、使用与 Motor Studio 兼容的固件更新 EVM  

(+)[常见问题解答] Motor Studio GUI - EVM 固件兼容性-电机驱动器论坛-电机驱动器- TI E2E 支持论坛

步骤1：使用新的固件更新 EVM

步骤2：安装 Motor Studio

步骤3：Test Motor Studio 会自动检测该设备。

 确认所有设置后、我将创建 一个运行 MPET 的参考 JSON、然后继续测试。

谢谢、此致

电路板版本为 MCF8315EVM Rev 1.0  M0070-001

MCF8315A_GUI 版本1.0.1  

尊敬的 John：

好的、您可以更新到 MOTOR Studio GUI、一旦可以更新、让我知道。

谢谢、此致

您好、Venkatadri

 现在情况要好很多。  我已经能够使电机以大约200rps 的速度驱动。  不过、它不是很稳定、需要很长时间才能加速。

欢迎提出任何改进这一点的建议。

谢谢

John
