Original question:

DRV10974: DRV10974启动运行几秒钟就停

DRV10983: 电机启动10秒左右后就停下

Part Number: DRV10983


我们在使用drv10983作为无刷电机的驱动板，原理图使用的是规格书上的示例，目前正在验证，出现了如下问题：

1.接入3.6V 50KHZ 占空比为50%的pwm波以后，电机启动加速了约10秒便停下，之后过一会又会自己启动。其他频率的PWM都有这样问题。

2.通过iic配置芯片，芯片在接收地址以后无应答，依旧重复上述的问题。

急盼解答！十分感谢。

下图为iic scl和sda的波形。

    您好为了更好地解决您的问题，您能否提供以下信息：

    1. EEPROM设置

    2. 电机停止转动的时候，有没有任何故障出现？

    3. 当电机在 10 秒后再次启动时，启动速度是怎么样的？正常吗？

    您好，目前芯片I2C已经通讯正常了，但电机还是无法正常运动。

    1.我将I2C写入读出的寄存器值放在这里

    2.没有故障出现

    3.启动速度与之前加速的速度一样，可以视其为正常。

    您好，启动问题可能是和tuning有关，如果您可以从寄存器 0x20-0x2B 中获取数据的话，您能否提供 EEPROM 设置？

    wu qingwei 说：
    2.没有故障出现

    那么当电机在停止运行前的那十秒，是否存在任何故障？ 再次启动时电机是否出现故障？

    同时您也可以参考DRV10983 tuning guide： https://www.ti.com/lit/ug/slou395d/slou395d.pdf
