  • I'm using this driver to run a stepper that's connected to a physical arm that spins around. I'd like to detect whether or not the arm is bearing any weight. I don't want the motor to stop or anything like that, I'd just like to know how hard the motor is working to spin the arm. I though I could do this by measuring how much current the stepper is drawing. The L6470 measures the current draw for its overcurrent detection, but I can't figure out if/how to read the actual current draw. Any help is greatly appreciated. Thanks !
