For additional stepper motor drivers see the Links below Further it is advisable to allow the stepper motor to remain at full current for at least 0. No availability reported, please contact our Sales office. The motor can be driven in half step, normal and wawe drive modes and on-chip PWM chopper circuits permit switch-mode control of the current in the windings. This item was manufactured prior to August 31, Since the phase are generated internally the burden on the microprocessor, and the programmer, is greatly reduced.
