The servo motor is a closed-loop servomechanism that uses position feedback to be able to control its rotational speed and position. The control signal is the input, either analog or digital, which represents the ultimate position command for the shaft.
Servo drives are designed to power and manage performance of electrical servomechanisms. They specifically monitor feedback signals and continuously adapt to deviations from the anticipated behavior of closed loop systems. This helps to improve efficiency through faster acceleration prices and more precise velocity and position control.
AC servo drives are specifically created for AC motors, and provide the added advantage of motor feedback. After getting and transmitting signals to produce motion, these drives also obtain and adjust to reviews from sensors on engine status. In providing constant adjustment, they amplify functionality in terms of the required velocity, torque, and position, in addition to stiffness, damping, and feedback gain in AC servo motors and control systems.
The Ever-power family of brushless servo systems is fully digital and offers a rich set of features to cover a broad range of applications. There are eight standard servo motors which can be managed in combination with among three regular 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 collection driver output leading to 10,000 pulses per revolution plus index indicate as the typical resolution within the drive. Each servo motor also offers one connector for the encoder and another connector for the electric motor power and optional 24 VDC spring-set keeping brake.
The servo drives could be configured for a wide range 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 selected 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-use SureServo Pro software on a Home windows environment.
