The servo motor is a closed-loop servomechanism that uses position feedback in order to control its rotational speed and position. The control signal is the input, either analog or digital, which represents the final position control for the shaft.
Servo drives are made to power and manage performance of electric powered servomechanisms. They particularly monitor feedback signals and continuously adapt to deviations from the expected behavior of closed loop systems. This can help to improve efficiency through faster acceleration prices and more precise quickness and position control.
AC servo drives are specifically created for AC motors, and offer the added advantage of motor feedback. After getting and transmitting signals to produce motion, these drives also obtain and adjust to reports from sensors on motor status. In providing constant adjustment, they amplify overall performance with regards to the desired velocity, torque, and position, in addition to 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 wide range of applications. There are eight regular servo motors that can be operated in combination with among three standard servo drives.
The Ever-power brushless motors add a 2,500 series incremental encoder with quadrature data signals (A+, A-, B+, B-) and a marker pulse (Z+, Z-). All three signals have a series driver output resulting in 10,000 pulses per revolution plus index tag 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 could be chosen with discrete inputs or modified with the MODBUS serial interface.
Configuration and diagnostics of the servo drives could be accomplished with the integrated keypad/screen or the easy-to-use SureServo Pro software program on a Home windows environment.
