The servo engine is a closed-loop servomechanism that uses position feedback to be able to control its rotational speed and position. The control transmission is the insight, either analog or digital, which represents the ultimate position command for the shaft.
Servo drives are made to power and manage performance of electrical servomechanisms. They specifically monitor feedback indicators and continuously adjust to deviations from the expected behavior of closed loop systems. This can help to improve efficiency through faster acceleration rates and more precise speed and position control.
AC servo drives are particularly made for AC motors, and provide the added advantage of motor opinions. After receiving and transmitting signals to produce movement, these drives also receive and adjust to reviews from sensors on engine status. In providing constant adjustment, they amplify performance in conditions of the required velocity, torque, and placement, as well as stiffness, damping, and opinions 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 set of features to cover a broad range 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 series incremental encoder with quadrature data signals (A+, A-, B+, B-) and a marker pulse (Z+, Z-). All three indicators have a collection driver output resulting in 10,000 pulses per revolution plus index indicate as the standard resolution within the drive. Each servo engine also has one connector for the encoder and another connector for the motor power and optional 24 VDC spring-set keeping brake.
The servo drives could be configured for a wide selection 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 modified with the MODBUS serial user 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 program on a Home windows environment.
