Tips for servo motors: Generally, PLC sends pulses, which are PLS pulses with fixed pulse width and interval. The number of square waves can be understood as "step pitch", which means that after one pulse, the servo motor needs to take "one step" (i.e. how many angles it rotates). Therefore, the more pulse square waves there are, the more angles the servo motor rotates. Therefore, the servo driver needs to output a waveform that can make the servo motor rotate by how many angles. However, servo motors cannot be simply completed by the motor structure like stepper motors. They need a position loop to do a closed loop, which is to measure how much the current motor angle changes by the pulse of the encoder, and then adjust the output voltage and output frequency through PID.

Servo motor tip 2: The servo driver needs to compare the received PLC pulses with the encoder pulses fed back by the motor (which can be simply understood as subtraction), and then output a value after PID calculation, which is then given to the so-called speed loop and current loop. After calculation, the IGBT module is controlled through PWM means, and a certain square wave is output to simulate a sine wave to control the speed of the servo motor to meet the desired angle and position of rotation. From a bottom-up perspective, the control of servo drives is similar to that of vector inverters.
