General Working Principle of Servo Systems

1. Controller
• Function: Receives external commands (e.g., signals from PLCs or motion controllers) and converts them into control signals recognizable by the driver (e.g., pulse signals, analog voltage/current signals, or communication protocol commands).
• Example: Sends position, speed, or torque target values via Ethernet (e.g., EtherCAT, Profinet) or fieldbus (e.g., CANopen).
2. Driver (Amplifier)
• Signal Processing: Receives commands from the controller (e.g., target position/speed) and compares them with the actual motor status feedback (e.g., encoder signals) to calculate deviations.
• PID Regulation: Adjusts output current/voltage through proportional-integral-derivative (PID) algorithms to eliminate deviations and make the motor move as commanded.
• Power Amplification: Converts low-power signals into high-power signals to drive the servo motor.
• Function: Amplifies the low-power control signals from the controller into high-power electrical energy required by the motor and adjusts the output based on feedback signals to achieve closed-loop control.
