INA226: stop giving current data when load is applied on the motor

Part Number: INA226

Hi,

I am having trouble in getting current data. I am running a small 3-phase DC motor and reading current values for the same. When the motor running freely without any load, the current data is fine but as I am applying load slowly, the current data becomes 0 and there is no further change in values.

What can be the possible reasons for it? PLease let me know.

Thanks in advance.

    Hello Rishabh,

    This sounds to me like the the wrong value may be being used for the calibration register.  Can you send me the values of all registers at a point when it fails? I will also need to know the shunt resistor value, and the maximum expected current.
