The servo engine is a closed-loop servomechanism that uses position feedback to be able to control its rotational speed and position. The control signal is the insight, either analog or digital, which represents the final position order for the shaft.

Servo drives are designed to power and manage performance of electric powered servomechanisms. They specifically monitor feedback indicators and continuously adapt to deviations from the expected behavior of closed loop systems. This helps to improve overall performance through faster acceleration rates and more precise acceleration and position control.

AC servo drives are particularly designed for AC motors, and provide the added advantage of motor feedback. After getting and transmitting indicators to produce motion, these drives also get and adjust to reports from sensors on motor status. In providing constant adjustment, they amplify efficiency with regards to the desired velocity, torque, and position, as well as stiffness, damping, and feedback gain in AC servo motors and control systems.
The Ever-power family of brushless servo systems is fully digital and will be offering a rich group of features to cover a broad range of applications. There are eight regular servo motors which can be operated in combination with one of three standard servo drives.

The Ever-power brushless motors add a 2,500 collection incremental encoder with quadrature data signals (A+, A-, B+, B-) and a marker pulse (Z+, Z-). All three indicators have a range driver output resulting in 10,000 pulses per revolution plus index mark as the typical resolution inside the drive. Each servo motor also offers one connector for the encoder and another connector for the motor power and optional 24 VDC spring-set holding brake.
SureServo Family
The servo drives can be configured for a wide range of command sources including analog torque, analog velocity, “step and direction” or “along” pulse position, quadrature encoder follower, and built-in movement controller with preset position, velocity, or torque. Presets can be chosen with discrete inputs or altered with the MODBUS serial interface.

Configuration and diagnostics of the servo drives could be accomplished with the integrated keypad/display or the easy-to-make use of SureServo Pro software on a Windows environment.
