ABSTRACT:
A control circuit for driving a step motor with at least first and second phase coils each having corresponding phase control elements. A memory stores phase switching data and is connected to the phase control elements. A first counter supplies phase switching data addresses to the memory to identify the coil or coils and phase thereof to be driven in response to step driving pulses and a second counter supplies data addresses to control the ON/OFF of the phase switching data and hence the phase current value. An oscillator drives the second counter at a frequency greater than the frequency of the step driving pulses.
