Understanding Servo Drives: Function, Types, and Industrial Applications

A servo drive is an electronic amplifier used to power electric servomechanisms.
It monitors the feedback signal from the servomechanism and continually adjusts for deviation from expected behavior.
A servo drive receives a command signal from a control system, amplifies the signal, and transmits electric current to a servo motor to produce motion proportional to the command signal.
The command signal represents a desired velocity, torque, or position, and a sensor attached to the servo motor reports the motor's actual status back to the servo drive.
The servo drive compares the actual motor status with the commanded motor status and alters the voltage, frequency, or pulse width to the motor to correct any deviation.
Stiffness, damping, and feedback gain are adjusted through performance tuning to achieve the desired performance of the servo motor.
Servo drives can be digital, analog, or both, and digital drives differ from analog drives by having a microprocessor or computer that analyzes incoming signals while controlling the mechanism.
Analog drives control velocity through various electrical inputs usually ±10 volts, often adjusted with potentiometers, and have plug-in "personality cards" preadjusted to specific conditions.
Servo systems can be used in CNC machining, factory automation, and robotics, among other uses, and their main advantage over traditional DC or AC motors is the addition of motor feedback.
The feedback is generally provided by an encoder of some sort, and servos, in constant speed-changing use, have a better life cycle than typical AC wound motors.
Servo motors can act as a brake by shunting off generated electricity from the motor itself, and many servo drives are now available that are compatible with a wide variety of motors.
While digital drives consume a large amount of energy, many install capacity batteries to monitor battery life, and traditional analog drives consume less energy than digital drives and can offer very high performance in certain cases.
