Conclusion
Conclusion
Although they were not designed specifically to implement microstepping, many of the
integrated motor control/drive circuits can be used to implement microstepping stepper
motor drives. The limits imposed by a peak detecting current control technique and the
selected decay mode will directly affect the performance of the motor drive, specifically its
ability to follow the desired current waveform. So long as these limits allow the designer to
achieve the desired resolution in the microstepping application the devices provide a cost
effective implementation.
