Series Servos (Digital Mode)

The GE Fanuc Digital

(pronounced “Alpha”) 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 (requires optional battery kit)

An optional motor brake is available

Optional IP67 environmental rating is also available for most motors

High resolution 64K count per revolution encoder feedback (incremental or absolute)

The GE Fanuc Servo motors, proven on over three million axes installed worldwide, offer the

highest reliability and performance. The latest technologies such as high speed serial encoders and

high efficiency Integrated Power Modules (IPM’s), further enhance customer benefits.

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, that is, a wide load inertia range, flexible acc/dec and position feedback configurations, etc.

Extensive customization features are available to optimize performance and overcome machine

limitations. IPM based servo amplifiers require 60% less panel space than conventionally

switched amplifiers and produce 30% less heat.

Series Integrated Digital Amplifier (SVU)

The

Series Integrated Servo Amplifiers (SVU) packages the amplifier with an integral power

supply in a stand-alone unit. This unit is the same physical size and footprint as the previous “C”

Series of GE Fanuc Servo Amplifiers.

The Integrated

Series SVU Amplifiers use the same connections as the “C” Series Amps except

that the Emergency Stop circuit uses the internal 24v supply, thus there is no longer a requirement

for a 100v power supply.

The heat sinks on the SVU design will mount through the panel to keep heat outside the

enclosure.

Since the

SVU Amplifiers do not provide regeneration to line capability, discharge resistors

may be required. These are available in several sizes.

SVU style

Series Servo Amplifiers are available in 5 sizes, with peak current limit ratings from

12 to 130 amps. (Note: Only the 80A and 130A models are currently offered by the GE Fanuc

NA motion group.)
