SR469-P5-HI-A20-E – 5-Axis High-Performance Servo Drive with Encoder Feedback for GE Fanuc Automation (Revision A20-E)

In stock

Product Introduction:
The SR469-P5-HI-A20-E is the encoder-feedback variant of the 5-axis servo drive module. The “E” suffix confirms that each of the five axes is equipped with high-resolution incremental encoder feedback, providing the highest level of positioning accuracy. This is the premium configuration for applications where absolute precision across all five axes is non-negotiable. The A20-E revision includes the latest firmware with advanced cross-axis coupling algorithms and improved thermal design for continuous high-load operation.

Technical Specifications:
Drive Type: 5-Axis Servo Drive (P5)
Performance Level: High-Performance (HI)
Revision: A20-E (Encoder feedback on all 5 axes)
Axes Controlled: 5 independent servo axes
Motor Power Per Axis: 0.5 kW to 3 kW (higher power than base A20)
Input Voltage: 200V AC to 480V AC (three-phase)
Output Current: Up to 15 Amps peak per axis
Feedback Type: Incremental encoder, 20-bit resolution, differential line driver (RS-422)
Control Modes: Position, Velocity, Torque, Electronic Cam, Gearing, Contouring
Communication: EtherCAT, PROFINET, Ethernet/IP, MECHATROLINK
Update Rate: 500 microseconds (faster than base A20)
Cross-Axis Bandwidth: 1 kHz for electronic gearing between axes
Operating Temperature: 0 to 45 degrees Celsius

Functional Features:
20-Bit Encoder Resolution: Provides 1,048,576 counts per revolution for ultra-fine positioning on all five axes.
500 Microsecond Update: Twice the speed of the base A20, enabling even smoother high-speed contouring.
Electronic Camming: Creates virtual cam profiles between any two axes for synchronized motion without mechanical cams.
Contouring Mode: All five axes move along a programmed path simultaneously with look-ahead algorithms for smooth corners.
Advanced Fault Diagnostics: Per-axis fault logging with oscilloscope-level data capture for troubleshooting.

Application Scenarios:
Aerospace Machining: Machines turbine blades and structural components requiring micron-level accuracy on all five axes.
Semiconductor Wafer Handling: Positions wafer stages with nanometer precision in lithography and inspection equipment.
Medical Device Manufacturing: Controls multi-axis machines that produce surgical instruments and implants with extreme accuracy.
High-Speed Packaging: Synchronizes cutting, folding, and sealing axes in pharmaceutical blister packaging.
