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 order for the shaft.
Servo drives are designed to power and manage performance of electric servomechanisms. They particularly monitor feedback indicators and continuously adjust to deviations from the expected behavior of closed loop systems. This helps to improve overall performance through faster acceleration rates and more precise swiftness and position control.
AC servo drives are specifically made for AC motors, and offer the added advantage of motor feedback. After getting and transmitting signals to produce motion, these drives also get and adjust to reports from sensors on motor status. In providing continuous adjustment, they amplify functionality when it comes to the desired velocity, torque, and placement, 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 offers a rich group of features to cover a broad selection of applications. There are eight standard servo motors that can be operated in combination with among 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 leading to 10,000 pulses per revolution plus index indicate as the standard resolution within the drive. Each servo engine also offers one connector for the encoder and another connector for the electric motor power and optional 24 VDC spring-set holding brake.
The servo drives can be configured for a wide selection of command sources including analog torque, analog velocity, “step and direction” or “along” pulse position, quadrature encoder follower, and built-in motion 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 can be accomplished with the integrated keypad/display or the easy-to-use SureServo Pro software on a Windows environment.
