GE-Fanuc Motion

GE Fanuc's S2K series servo amplifiers convert a torque, velocity, or pulse signal from an external controller to the proper current required to drive the servo motor. They offer improved high-speed performance, robust power blocks to eliminate overheating during motor stall, compatibility with microstepping resolutions, and reduced servo tuning requirements with self-tuning, all-digital drive. Compact design minimizes valuable panel space requirements.

The GE Fanuc S2K series products offer amplifier and control capability for servo and stepping motor systems in a standalone integrated package. These products incorporate all-digital amplifier technology and fast servo update rates for enhanced performance. The DeviceNet implementation includes the ODVA-defined position controller master-slave protocol as well as peer-to-peer control for multi-axis standalone systems.

Features and Benefits

Wide torque from 5.7-322 lb-in (0.64-36.3 Nm)
Control either torque, velocity or position mode
Comprehensive front panel diagnostics
Auto tuning function.

The SL series servo family is comprised of the Z-Series and the V-Series components. The Z-Series amplifiers cover servos from 30 Watt to 750 Watt continuous rating. The V-Series covers servos from 1,000 Watt to 5,000 Watt continuous rating. While many of the functions and configuration parameters are the same from both series, there are a number of differences. One of the primary differences is the I/O configuration on the CN I/F interface connector of the amplifier. The V-Series uses a 50-pin interface connector and contains several signals not included on the A-Series amplifiers. The Z-Series amplifiers use a 36-pin interface connector and use parameter configurations to assign different I/O functions to some of the connector pins.

Features and Benefits

Continuous stall torque from 0.84-140 in-lb (0.095-15.8 Nm)
Compact amplifier design conserves critical panel space
User configurable control modes for position, velocity or torque control
High torque-to-inertia ratios provide high performance in a small package
On-the-fly control mode switching for dual control of position, velocity, or torque

The modular design Alpha Servo Amplifier offers the advantages of compact size and efficiency. A single power supply provides DC power to multiple amplifiers, either servo or spindle. This offers the advantage of higher efficiency, higher reliability, and lower cost rather than having individual power supplies for each servo and spindle.

The Alpha Series Servo Amplifiers provide the latest IPM technology. Amplifiers are available in seven sizes, with peak current limit ratings from 12 amps to 360 amps. In addition, both dual- and triple-axes amplifiers are offered for even more panel space savings.

The GE Fanuc high-performance Alpha Series digital AC Servo Drives are available in a range of sizes for use with GE Fanuc CNCs, Power Mates and Series 90-30 PLC controllers. The highest possible resistance to environmental noise is provided by the fiber-optic serial servo bus (FSSB), and the serial-encoder feedback, further supporting machine uptime. Closing the control loops in the CNC also provides comprehensive, real-time information of every aspect of the machine and drive system dynamics, enabling superior performance of the advanced algorithms, particularly those used in high-speed machining. Advanced digital signal processors in the CNC allow high-speed processing of current and position feedback resulting in smoother surface finish and higher accuracy parts.

High productivity with high-quality machining throughout the cutting range is provided by superior construction, and a unique skewed magnet arrangement that delivers high acceleration to high speeds and smooth operation and high torque at low speeds.

Features and Benefits

World-leading reliability
Digitally set parameters, no re-tuning required
High resolution 64K count per revolution incremental encoder feedback
An optional brake
AC line regeneration
An optional IP67 environmental rating available for most motors
Optional 64K or 1 Million count per revolution absolute encoders; eliminate re-homing

The Beta Series Servo amplifier integrates a power supply with the power switching circuitry, resulting in a compact amplifier that is 60 percent smaller than conventional models. In fact, the Beta series amplifier has the same height and depth as a GE Fanuc Series 90-30 PLC module. The amplifier is designed to conform to international standards - European CE, North American UL, and Canadian CSA.

Features and Benefits

World-leading reliability
Low maintenance
The latest technologies, such as high-speed serial encoders and high-efficiency Integrated Power Modules

The Beta Series servo motors are built on the superior technology of the Alpha Series servos. They incorporate several design improvements for the best performance possible with reduced cost and size. Ratings of 5.3 in-lb (0.6 Nm) to 105 in-lb (12 Nm) are offered.

These motors are up to 15 percent shorter and lighter than comparable servos. A smaller rotor means less mass and therefore better acceleration for higher machine cycle rates. New insulation on the windings and an overall sealant coating help protect the motor from the environment.

The Beta motors conform to international standards (IEC). The motor protection level is IP55. A 32K absolute encoder is standard with each Beta Series Servo. An optional holding brake is also available with each model.

The GE Fanuc high-performance Beta Series digital AC Servo systems are available in a range of sizes for use with GE Fanuc PowerMotion and CNC control systems. The Beta Series Servo systems offer the highest reliability and performance. Designed with the motion control market in mind, the Beta Series Servo drives are ideally suited for the packaging, material handling, converting, and metal fabrication industries.

The GE Fanuc S-Series motors are both versatile and rugged. They are used with both the S2K and SL Series products. These motors use high-energy neodymium rare earth magnets for superior cost/performance ratios.

The Power Cube stepping motor-drive package provides a cost-effective solution for OEM stepping motor applications in a rugged and easy-to-install package. The Power Cube is ideal for high-volume applications such as packaging and material handling. It accepts pulse and direction inputs from an external pulse source such as the GE Fanuc Operator Control Station stepping control module. And unlike many low-cost stepping motor drives, the Power Cube has a high-performance, bipolar chopper design that maintains constant current in a wide range of operating conditions.

Power Cube Features
Like all GE Fanuc products, the Power Cube incorporates key design features to provide the flexibility, performance, and ease of service you demand.
