| In some microstepping drivers the frequency is dependent on the supply, and the stepper inductance. On others it is a fixed fixed value, or may change dynamically depending on speed and current setting. Why do you want to control it? Just drive the step pulses to the speed you want to go, within the specs for the driver/motor/voltage combination. Above some minimum speed the acceleration/deceleration need to be controlled so steps are not missed because the inertia of the machine becomes an issue.
