Abstract
A stepper control circuit includes numerical controlled oscillators configured to provide step signals for multiple axes of stepper motor movement. The numerical controlled oscillators are configured to be operated at a same frequency provided by a synchronized clock signal.
Claims18
A stepper control circuit comprising:
- a first numerical controlled oscillator configured to provide step signals for a first axis of stepper motor movement;
- and
- a second numerical controlled oscillator configured to provide step signals for a second axis of stepper motor movement;
- wherein the first and second numerical controlled oscillators are configured to be operated at a same frequency provided by a synchronized clock signal.
