A servo drive, sometimes referred to as an amplifier, takes the command signal for position, speed or torque requirement and adjusts the voltage and/or current applied to the servo motor using closed loop control.
A servo drive is an integral part of a servo system which also includes the controller, motor and feedback device. Communication to and from controllers and other devices can be via a simple digital and analogue i/o or digital fieldbus communication, such as EtherCAT, CANopen and many other industry standard protocols.
What are Servo Drives used for?
Servo drives are generally used to control the speed, position and torque of brushless servo motors. They come in a variety of sizes and are suitable for static and mobile applications across many industries including:
