器件型号：MCF8316AEVM 您好！
即使在断开电源后、电机有时也运行良好、有时电机根本无法启动、或者启动不佳、并且会显示错误消息。
电源设置尚未更改。 所有设置应存储在 EPROM 中。 什么可能是错误、什么是错误的做法？
此致！

您好、Hong：
当然可以。 对发动机进行参数化后、发动机启动良好。 甚至在我断开电源并重新连接后、一切仍然正常。 但是、如果在相同条件下不使用一天、它并不总是能可靠地启动。 另外、启动行为改变了这种情况、不再像编程那样缓慢、而是非常粗略。 有时它根本不会启动、并显示错误消息"Abnormal BEMF Fault (异常 BEMF 故障)"。 我在干什么？
此致！
利纳斯
您好、Hong：
我已经附加了两个文件。 该文件之一是寄存器的状态、在该状态下、即使在断开电源后一切都已经顺利运行。

我只能想象它与组件中的温度有关。 其余条件相同。
也许您有其他想法。
此致！
利纳斯
您好、Linus：
我们注意到、您的 IPD 电流阈值(GUI 中"电机启动固定"下的 IPD_CURR_THR)和闭环电流限制(GUI 中"闭环"下的 ILIMIT)设置为6.0A、但您的开环电流限值(GUI 中"开环"下的 OL_ILIMIT)设置为1.5A。 这可能会限制驱动器提供扭矩的能力、从而导致启动不一致和电机取消同步、从而导致异常 BEMF 故障。 尝试将开环限制设置为更接近闭环限制的值。 此外、我们建议您将 IPD 电流阈值设置为电机峰值额定电流的一半(设置为8.0A/2 = 4.0A)。
此外、您是否通过 MPET 获得了 R、L 和 Ke 的值？ 如果尝试上述操作后仍出现异常 BEMF 故障、则电机可能很小 、可能必须手动测量参数。
如果上述操作不起作用、您能否提供电机启动、加速和闭环(成功和失败的尝试)时的相电流捕获？
此致！
