TI中文支持网Other Parts Discussed in Thread:TMS320F28027, BOOSTXL-DRV8305EVM
我使用的是基于BOOSTXL-DRV8305EVM和TMS320F28027板子，电机最大电流25A，Kv2000，在使用lab02c时，电机总是在RampUp阶段不转动。
按照User Guide里说的，逐渐加大USER_MOTOR_RES_EST_CURRENT，到达2A以上时，板子上的nFault指示灯就会亮起；
然后识别的参数误差会很大，电机也不转动；
当我仅使用航模所用的电调，输入PWM信号时，电机可以转动，电流达到1.2A左右，但是使用识别电路板，电流到达1.1A左右或者以上时，nFault灯常亮；
想问一下，怎么查找nFault灯亮的故障码？在程序里哪个变量里可以看到？
其次，怎么继续增大USER_MOTOR_RES_EST_CURRENT，nFault指示灯才不会亮，并且电机能够转动，完成电机识别过程呢？
以下是我的user.h文件 内容：

Susan Yang：
1.请设置正确的增益，并在user.h中设置相应的USER_ADC_FULL_SCALE_CURRENT_A和USER_ADC_FULL_SCALE_VOLTAGE_V。
2.根据您的电动机设置正确的USER_MOTOR_RES_EST_CURRENT，USER_MOTOR_IND_EST_CURRENT和USER_MOTOR_FLUX_EST_FREQ_Hz。另外对于电机识别，电机需要在空载或轻载下工作，尤其是对于Ls和磁通量识别
,
Alex He：
我确定我所设置的USER_ADC_FULL_SCALE_CURRENT_A和USER_ADC_FULL_SCALE_VOLTAGE_V均根据硬件设置正确，且USER_MOTOR_RES_EST_CURRENT，USER_MOTOR_IND_EST_CURRENT和USER_MOTOR_FLUX_EST_FREQ_Hz的设置也按照手册设置，区别在于我所使用的电机是不得不带负载的油泵电机，按照使用手册需要更大的USER_MOTOR_RES_EST_CURRENT，但是我将此数值增大到2A以上时，电机仍然不转动，且在RampUp阶段，板子的nFault指示灯常亮。
我联系了设计电路板的人员，基本排除硬件的限流原因，现在想知道在软件中，是否有对估算电流的限幅？如果有的话，在哪里可以更改呢？
,
Susan Yang：
根据手册说明
另外请参考E2E上相关帖子
,
Alex He：
我从1.0A开始设置，以0.1为增量逐渐增加，当电流达到2.0A时，电机依然没有转动，继续增大该值，就会出现板上nFault指示灯常亮，识别过程还在继续，但是电机不转，识别出的参数数值很小，严重偏离实际值。
,
Susan Yang：
谢谢您的反馈，我们会在研究确认后给您回复。
,
Susan Yang：
看起来是未正确识别电动机。请在电动机上不加任何负载进行识别，并根据电动机的规格在user.h文件中设置正确的识别变量值，以确保在磁通量测量和Ls识别状态下电动机平稳旋转。
#define USER_MOTOR_RES_EST_CURRENT(1.0)// A - 10-30% of rated current of the motor#define USER_MOTOR_IND_EST_CURRENT(-1.0)// A - 10-30% of rated current of the motor, just enough to enable rotation#define USER_MOTOR_MAX_CURRENT(5.0)// A - 30~150% of rated current of the motor#define USER_MOTOR_FLUX_EST_FREQ_Hz(20.0)// Hz - 10~30% rated frequency of the motor
,
Alex He：
我的电机需要带动油泵才能够正常运转，不得不带负载运行；
根据所给定的数据，以及我自己调试的数据来看，电机无论在哪个参数下都无法平稳旋转；因为电机根本就没有在旋转；根据使用手册，我应该增大
#define USER_MOTOR_RES_EST_CURRENT(1.0)// A - 10-30% of rated current of the motor但是，增大该变量到2A，电路板上报错，就无法再驱动电机了。
