I am trying to set a current limit for the stepper motor (full step mode), but not sure if this is the right way I am doing it. I just want to be sure that I get everything out of this motor that i can.
I use LDO-42STH47-1684AC stepper motor and the specifications of this motor can be found here: http://i00.i.aliimg.com/img/pb/573/914/609/609914573_464.jpg
Stepper motor I use have a maximum current rating of 1.68A/phase. In full step mode, the current through the coils is limited to 70% of the current limit, so to get a full step coil current of 1.68A, the current limit should be 1.68/0.7 = 2.4A, which corresponds to a VREF of 2.4A/2.5 = 0.96V
I used potentiometer on the board to set a VREF to 0.96V and I checked it from the + probe on the turnpot and - on a ground pin with multimeter.
Is the right way of setting the current limit?
