The servo electric motor is a closed-loop servomechanism that uses position feedback to be able 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 electrical servomechanisms. They particularly monitor feedback signals and continuously adapt to deviations from the anticipated behavior of closed loop systems. This can help to improve overall performance through faster acceleration prices and more precise rate and position control.
AC servo drives are particularly designed for AC motors, and provide the added advantage of motor opinions. After receiving and transmitting signals to produce motion, these drives also get and adjust to reviews from sensors on engine status. In providing constant adjustment, they amplify overall performance in terms of the required velocity, torque, and placement, and also stiffness, damping, and opinions gain in AC servo motors and control systems.
The Ever-power category of brushless servo systems is fully digital and offers a rich group of features to cover a wide selection 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 include a 2,500 range incremental encoder with quadrature data signals (A+, A-, B+, B-) and a marker pulse (Z+, Z-). All three signals have a collection driver output resulting in 10,000 pulses per revolution plus index mark as the typical resolution within the drive. Each servo engine also has one connector for the encoder and another connector for the electric motor power and optional 24 VDC spring-set keeping brake.
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 motion controller with preset position, velocity, or torque. Presets can be selected with discrete inputs or modified with the MODBUS serial user interface.
Configuration and diagnostics of the servo drives can be accomplished with the integrated keypad/display or the easy-to-use SureServo Pro servo motor software on a Windows environment.
