In stock

Product Introduction:
The SR489-P1-LO-A20-E is a compact, low-power single-axis servo drive designed for GE Fanuc Automation platforms. The “P1” indicates one axis, “LO” denotes low-power capability (typically under 500W), and “A20-E” indicates the revision with encoder feedback. This drive is optimized for small servo motors used in light-duty applications such as small conveyors, valve actuators, lightweight robot axes, and packaging machines. Despite its small size, it delivers the same high-performance control algorithms as the larger HI-series drives, making it the ideal choice for applications where space and power are limited but performance is still important.

Technical Specifications:
Drive Type: Single-Axis Servo Drive (P1)
Performance Level: Low-Power (LO)
Revision: A20-E (with Encoder)
Motor Power Range: 50W to 500W
Input Voltage: 100V AC to 240V AC (single-phase or three-phase)
Output Current: Up to 5 Amps peak
Feedback Type: Incremental encoder, up to 17-bit resolution
Control Modes: Position, Velocity, Torque
Communication: EtherCAT, PROFINET, Ethernet/IP, Pulse/Direction
Update Rate: 1 millisecond servo loop

Form Factor: Compact module (smaller than HI-series, fits in tight spaces)

Functional Features:
Compact Form Factor: Significantly smaller than the HI-series drives, allowing dense packing in small control cabinets.
Single-Phase Input: Accepts 100-240V single-phase power, eliminating the need for three-phase power in small machines.
Quiet Operation: Optimized PWM algorithms minimize audible motor noise, ideal for office-adjacent equipment.
Auto-Tuning: One-button auto-tuning simplifies commissioning for non-expert users.
Built-In Brake Control: Supports motor brake release and engage sequences for vertical axis applications.

Application Scenarios:
Small CNC Machines: Drives the axes of desktop CNC mills and laser engravers.
Valve Actuators: Controls the position of control valves in HVAC and process piping with precise positioning.
Lightweight Robots: Powers the axes of small collaborative robots (cobots) used in assembly and inspection.
Laboratory Automation: Drives sample stages, pipetting heads, and analytical instrument positioning systems.
