器件型号：MCF8329EVM
主题中讨论的其他器件： MCF8329A

您好！

我们在调整 MCF8329EVM 以使用(低功耗) Maxon 电机时遇到问题。

(请注意、我们仍在评估电机、我们选择了 MCF8329而不是 MCF8316、因为它在电源输出和最大总线电压方面提供了更大的灵活性)

我们无法获得 MPET 来正确估算参数、但幸运的是、我们提供了数据表参数作为参考、具体如下：

经过试错后、我们似乎有一致的启动和开环加速(空载)、但是电机达到特定的 RPM 并停止、然后我们在 Motor Studio 中遇到以下故障： 控制器故障 ， ABN_BEMF ， 广播_ LCK 。下面的日志片段：

15:46:33:955 | : Accelerating motor in open loop control...

15:46:32:944 | : Performing motor stationery startup...

对于如何调试/调整这个斜升/切换、是否有任何建议？

这是我们的.json 文件、供参考。

您好、J：

查看发送的寄存器配置后、我建议进行以下更改：

将 THETA_ERROR_RAMP_RATE 降低至 0.5度/MEG
异常_BEMF_THR 下限高达70%
将 AUTO_CHANDOFF_MIN_BEMF 降至100mV

如果这些变化仍然会导致 ABN_BEMF 故障出现、请禁用 LOCK2_EN、并查看电机是否能够在没有遇到故障的情况下进入闭环。如果禁用 LOCK2_EN 后它未发生故障、则需要更多的转换调优、否则可能需要首先校正不同的问题。

我将在周五回复您。

感谢 Joshua 的快速响应、

好消息、在您的帮助下、我们已经通过以下更改使电机持续旋转闭环：

将 THETA_ERROR_RAMP_RATE 降低至 0.5度/MEG
异常_BEMF_THR 下限高达70%
将 AUTO_CHANDOFF_MIN_BEMF 降至100mV
禁用 LOCK2_EN
将 ALIGN_SLOW_RAMP_RATE 更改为10A/s
将 ALIGN_OR_SLOW_CURRENT_LIMIT 更改为30%
将 IPD_CURRENT_THR 更改为30%
将速度环路的 Kp 系数更改为2.55
将速度环路的 Ki 系数更改为0.01

我们仍有以下问题：

在启用 LOCK2_EN 时电机不会启动(与上述错误相同)
电机的运行速度不会低于~30%(可能需要增大分流电阻？)
电机开环切换速度相当高

您好、J：

您能否提供从空闲开始直到器件发生故障或进入闭环的相电流的捕获数据？

您能让 MPET 测量 BEMF 以及速度增益 KP 和 KI 吗、看看结果是什么。在运行 MPET 之前、请确保电机无负载。若要运行 MPET 以便它只测量 BEMF 和速度增益、请使用 MPET 页面并在"MPET Select"下切换底部的两个开关、如下图所示：

请确保未启用电机电阻或电机电感、因为这些测量在 MCF8329A 器件上不起作用。 MPET 测得的速度增益和 BEMF 常数应该相对接近您正在使用的值、如果它们不是、我建议使用 MPET 测量值。

此致、

约书亚

我们已经花了一些时间尝试使 MPET 正常工作(测量 BEMF/机械参数)。

我们不断遇到一个奇怪的问题、即电机开始旋转(算法状态：MOTOR_MPET_KE_measure)、电流将继续斜升(~100mA 每秒)、直到达到电源 OC 设置(24V 下~1.5A)。

是否有关于导致此行为的原因有任何建议？

谢谢、

J 您好、

OL_ILIMIT 设置为 BASE_CURRENT 的20%、即9.375A *.2 = 1.875A。在开环模式下、电机将继续增加提供的电流、直到达到 OL_ILIMIT。我建议将 OL_ILIMIT 设置为10%、以便将开环电流限制设置为 0.9375A。

更新 OL_ILIMIT 已修复过流问题。

我们的下一个 MPET 问题是、转子仅以特定速度旋转、然后锁定会导致电机振动。

我们已尝试减小 MPET_OPEN_LOOP_SLEW_RATE 和增加 MPET_OPEN_LOOP_CURR_REF、但未成功。

是否有任何其他可调节 MPET 斜升的参数？

J 您好、

您能否提供 MPET 运行时的相电流捕获？
电机的最大额定电流是多少？如果电源设置为1.5A、我假设这接近电机的额定最大相电流？如果1.5A 接近电机的额定最大电流、我建议更改所用的 CSA 增益和 R_sense、以便 base_current 更接近电机的额定最大电流。

谢谢 Joshua、

我将回顾该视频、并着手获取一些相电流捕获。
我们还将安装值更高的分流电阻器、以便针对目标电机更合适地配置 base_current。

我会在收到更多信息后办理入住。
