Analysis of the working principle of servo drives and considerations for selecting servo drives

Servo drive is an indispensable component in modern industrial automation, mainly used to control the operation of servo motors

. Its core function is to convert input control signals (such as voltage and current signals) into mechanical motion of the motor.

The following is an introduction to the basic working principle of servo drives:

Input signal processing: The servo drive receives command signals from the control system, which may be analog signals (such as

voltage or current) or digital signals (such as pulse sequences).
Signal conversion: The control circuit inside the driver converts these signals into control signals that the motor can understand, such

as PWM (Pulse Width Modulation) signals.
Current control: The servo driver controls the speed and torque of the motor by adjusting the current output to the motor. This is usually achieved through internal power transistors.
Speed and position feedback: Servo motors are usually equipped with encoders to provide actual speed and position feedback of the motor.

These feedback signals are sent back to the driver for comparison with the expected position or velocity.
Closed loop control: Based on feedback signals, the internal control algorithm of the driver (such as PID controller) will adjust the output signal to

reduce the deviation between actual and expected, achieving precise control.
Protection function: The servo drive also has overload, overheating, overvoltage and other protection functions to ensure the safe operation of the motor and drive.
