The servo motor is a closed-loop servomechanism that uses position feedback in order to control its rotational speed and position. The control transmission is the input, either analog or digital, which represents the final position control for the shaft.
Servo drives are created to power 
and manage performance of electric powered servomechanisms. They particularly monitor feedback indicators and continuously adapt to deviations from the expected behavior of closed loop systems. This helps to improve efficiency through faster acceleration prices and more precise acceleration and position control.
AC servo drives are specifically created for AC motors, and offer the added benefit of motor opinions. After getting and transmitting indicators to produce motion, these drives also receive and adjust to reviews from sensors on electric motor status. In providing continuous adjustment, they amplify functionality when it comes to the required velocity, torque, and position, along with stiffness, damping, and feedback gain in AC servo motors and control systems.
The Ever-power category of brushless servo systems is fully digital and will be offering a rich group of features to cover a broad selection of applications. There are eight standard servo motors which can be operated in combination with one of three standard servo drives.
The Ever-power brushless motors include a 2,500 range incremental encoder with quadrature data signals (A+, A-, B+, B-) and a marker pulse (Z+, Z-). All three indicators have a line driver output resulting in 10,000 pulses per revolution plus index mark as the typical resolution within the drive. Each servo motor also has one connector for the encoder and another connector for the electric motor power and optional 24 VDC spring-set keeping brake.
SureServo Family
The servo drives can be configured for a wide variety of command sources including analog torque, analog velocity, "step and direction" or "up and down" pulse position, quadrature encoder follower, and built-in movement controller with preset position, velocity, or torque. Presets could be chosen with discrete inputs or altered with the MODBUS serial user interface.
Configuration and diagnostics of the servo drives could be accomplished with the integrated keypad/screen or the easy-to-make use of SureServo Pro software on a Home windows environment.
