Communication interface of intelligent subdivision controller of stepper motor

The communication interface of sine constant current of high subdivision drive controller of stepper motor is proposed based on the technology of microprocessor and communication. The microprocessor and computer can communicate with each other, which can realize the real-time monitoring of running conditions of stepper motor. The running information includes the operational status, real-time waveform of phase current of motor, and so on. All these information of the stepping motor can be uploaded to the upper PC. The subdivision controller of stepper motor has the function of communication. The low-pass filter of hardware and anti-interference filter of software are designed. The sampling information is processed. The accuracy of sampling information is enhanced.
