Nearly all stepper drivers deliver a constant current to the motor. While the nominal voltage needed for a stepper is essentially “irrelevant”, setting the correct voltage determines the current available for the stepper, by the driver. Ohms law is only really applicable to a stepper motor when it is not moving.
A minimum voltage is still required to overcome back-EMF.
Without going into the maths, your voltage settings determines your available current, basically.
