Series Servos (Digital Mode)

The GE Fanuc Digital

(pronounced “Beta”) Series Servo features include:

World leading reliability

Low maintenance, no component

drift

, no commutator brushes

All parameters digitally set, no re-tuning required

Absolute encoder eliminates re-homing (optional battery kit required)

Optional motor brake

High resolution 32K count per revolution encoder

The GE Fanuc

Series Servos offer the highest reliability and performance. The latest

technologies, such as high-speed serial encoders and high efficiency Integrated Power Modules,

further enhance the performance of the servo system. Designed with the motion control market in

mind, the

Series Servo Drives is ideally suited for the packaging, material handling, converting,

and metal fabrication industries.

The GE Fanuc servo system is unique in that all the control loops - current, velocity, and position

- are closed in the motion controller. This approach reduces setup time and delivers significant

throughput advantages even in the most challenging applications.

The servo drives are less costly to integrate and maintain. Control circuits are unaffected by

temperature changes. There are no

personality

modules. The servos have a broad application

range including a wide load inertia range, flexible acceleration/deceleration and position feedback

configurations. Extensive software customization features are available to optimize performance

and overcome machine limitations.

Series Digital Amplifiers

The

Series servo amplifier integrates a power supply with the switching circuitry. Therefore,

GE Fanuc is able to provide a compact amplifier that is 60% smaller than conventional models.

In fact, the

Series amplifier has the same height and depth as a GE Fanuc Series 90-30 PLC

module. This allows efficient panel layout when using the DSM314 motion controller.

The amplifier is designed to conform to international standards.

GE Fanuc offers three communication interfaces for the

Series amplifiers: pulse width

modulated (PWM), Fanuc Servo Serial Bus (FSSB), and I/O Link Interface. Only the pulse width

modulated (PWM) interface may be used with the DSM314 module. The PWM interface utilizes

the standard GE Fanuc servo communication protocol. Position feedback is communicated

serially between the DSM controller and the motor mounted serial encoder.
