Working principle of DMC2 50412P-CAN

The working principle of servo driver mainly includes signal processing, PID regulation, current control and drive output:

Signal processing: The servo driver first conducts signal processing on the received instructions of the upper computer, including decoding, filtering, sampling and other operations, and converts the instructions of the upper computer into signals suitable for the control of the servo motor.

PID adjustment: According to the signal after signal processing, the control parameters of the servo motor are adjusted through the PID (proportional-integral-differential) regulator. The PID controller calculates the corresponding control amount according to the size and change trend of the error signal, so as to realize the precise control of the servo motor.

Current control: According to the output of the PID regulator, the current of the servo motor is controlled by the current controller. The current controller adjusts the current size and direction of the servo motor to ensure that the motor operates in a predetermined manner.

Drive output: The output signal of the current controller is converted into a drive signal, and the servo motor is driven by the drive circuit. The drive circuit includes power amplifier, pulse generator and other components, which can realize the efficient drive of servo motor.
