Check my thinking here: Using the ProV3 controller, NEMA 23 steppers and 24VDC power supply. Stepper Motor data says the rated current/phase is 2.8A and the resistance/phase is .9 ohms. The resultant voltage (I X R =E) is 2.52volts. So do I adjust the trim pot to approximately that voltage to achieve the rated current to the stepper motor? Thanks!
