Hi, 

I am kumari. I am using drv10983 for bldc motor. Using Usb2any explorer board i configure the setting of drv10983 its working perfectly. but after switch off the board. the settings will be changed. again if i give the power means motor is not working. So after power on the board i need to configure the settings again. Can u tell me the solution of problem

    Hey Kumari,

    When you configure the settings using the USB2ANY, you are programming the values into volatile memory which means the contents will be lost after power cycling (as you described).

    Clicking the "eeWrite" button on the Basic Settings tab below the Motor Parameters section will program "most" of the content (only the registers SysOpt1-SysOp9) of volatile memory into EEPROM, which is nonvolatile memory. Then, your settings will be saved even if you power cycle because EEPROM will load the settings into volatile memory during power up.

    If you are not using the USB2ANY or what to learn more about programming EEPROM, check the Non-Volatile Memory section in the datasheet.

    Best,

    -Cole

    Edit: Make sure VCC = 24V when programming, the EEPROM circuit requires 24V to successfully program registers into EEPROM.
