A servo drive is an electronic amplifier that receives commands from a motion controller and sends power to a servo motor to produce the desired motion. It continuously adjusts the motor’s voltage and current based on feedback, ensuring accurate control of position, speed, and torque.
🔧 How It Works:
Command Input: The servo drive receives a motion command (e.g., move to a certain position at a certain speed).
Feedback Loop: It gets real-time data from sensors (typically an encoder or resolver) on the motor shaft.
Error Correction: It compares actual motor performance with the commanded values and adjusts power to minimize any difference.
Motor Control: It precisely regulates the motor’s behavior, often in milliseconds or microseconds.
