DRV10987EVM: Software interface font exception

Cherry Zhou

Part Number: DRV10987EVM

Hi team,

1) DRV10987EVM Software Interface Font Display is incomplete, what could be the possible cause? Windows 11 and Windows 7, 64-bit systems are used. 

2) Software interface to set up the analogue speed to control motor, the motor will turn for a few seconds and then stop, and turn and stop again (repeated stalling). Also, the speed is low and the analogue resistor speed is unchanged. Is it a software issue? 

Could you help check this case? Thanks.

Best Regards,

Cherry

    Hi Cherry,

    The GUI screenshot that you shared is just an interface to send I2C commands to the device on the EVM. I see that the GUI is in Demo mode and some of the parameters are programmed as zero. Device registers have to be tuned to spin the  ktor in closed loop. Please refer to the User's guide and tuning guide for the setup and tuning instructions.

    您好！
           感谢提供的调优文档，  我对GUI的参数设置不是很了解，我会仔细研读。参数设置如下图，风机转子在颤抖，但是转不起来，模拟量调节需要设置哪些参数？另外还有两个问题，1.Display界面 Supply voltage (V) 是205，但是我使用的电压是24V ，这个是软件问题吗？  2.界面参数名称字体太大，不能现在完整，字体大小怎么调节？

    Hi Peter,

    I see that the software current limit is set too low. For now, please disable it. Can you check the lock code in "Display" tab and check what fault is getting triggered? Can you also share the phase current waveform? What is the end equipment that you are working on? Supply voltage is read back only when the device is spinning the motor. 

    Regards,

    Vishnu
