what is servo drive and how it works?
A servo drive is an electronic component that controls a servo motor 's position, speed, and torque with high precision. It works as part of a closed-loop system , receiving commands from a controller , sending power to the motor, and using a feedback sensor (like an encoder ) to constantly monitor the motor's actual state and make real-time adjustments. This continuous comparison between the commanded and actual motion allows for accurate and responsive performance, essential for automation , robotics , and CNC machines . Receives commands: A host controller sends a command signal to the servo drive specifying a desired position, speed, or torque. Powers the motor: The servo drive amplifies the command signal and adjusts the voltage and current it supplies to the servo motor to produce the commanded motion. Uses feedback: A sensor (such as an encoder) attached to the motor continuously monitors its actual position, speed, and/or torque. Compares and corrects: The driv...
