CPU214 has two pulse outputs that can be used to generate pulses for controlling stepper motor drivers. The power driver converts the control pulse into the current of the stepping motor coil according to a certain mode, generating a rotating magnetic field, so that the rotor can only change its position according to a fixed number of steps (step a)

A continuous pulse sequence generates its corresponding synchronous machine step sequence with the same frequency. If the control frequency is high enough, the rotation of the stepper motor can be regarded as a continuous rotation—-

This example describes the use of Q0.0 output pulse to trigger a stepper motor driver. When the input terminal I1.0 sends a “START” signal, the controller will output a fixed number of square wave pulses, causing the stepper motor to rotate according to the corresponding number of steps. When the input terminal I1.1 sends a “STOP” signal, the stepper motor stops rotating. The direction switch position connected to input terminal I1.5 determines whether the motor is rotating forward or backward
