Working Principle
The Lichuan AC Servo Motor Drivers Kit operates as a high-precision closed-loop control system, following these key steps:
-
The servo driver receives control commands (position, speed, or torque) from the upper controller (PLC, HMI, or CNC system).
-
The driver converts these commands into precise three-phase AC signals to drive the servo motor, ensuring accurate motion output.
-
The motor’s built-in 23-bit encoder collects real-time position and speed data, feeding it back to the servo driver continuously.
-
The driver compares the feedback data with the target command values, dynamically adjusting the output signals to eliminate control errors, achieving high-precision closed-loop control for theAC Servo Motor Drivers Kit.
