Typical Application Scenarios

The SP2403 Unidrive SP AC Servo Drive has proven its value across multiple heavy-duty industries:

• Oil & Gas: Controls pump and compressor drives in upstream and downstream facilities where continuous duty cycles demand robust, fail-safe operation.
• Power Plants: Manages auxiliary motor drives for cooling fans, feedwater pumps, and conveyor systems, ensuring grid-synchronized performance.
• Automotive Manufacturing: Deployed in robotic welding cells and assembly line conveyors requiring sub-millisecond response times and electronic gearing.
• Pharmaceutical & Food Processing: Delivers repeatable torque profiles for filling, capping, and packaging machines operating under strict hygiene and precision standards.
• Pulp & Paper / Metals: Handles winding and unwinding tension control in continuous process lines where speed regulation directly impacts product quality.

Core Features & Technical Advantages

1. Robust Vector Control Algorithm: Delivers heavy-duty torque accuracy across the full speed range, eliminating speed droop under variable load conditions.
2. Multi-Protocol Communication: Native support for Modbus RTU, CANopen, and Ethernet/IP ensures seamless integration into any existing PLC System or DCS architecture.
3. Precision Servo Positioning: Closed-loop encoder feedback enables sub-degree positioning accuracy, critical for CNC and robotic applications.
4. Comprehensive Protection Suite: Built-in safeguards against overcurrent, overvoltage, undervoltage, and thermal overload extend drive lifespan in harsh environments.
5. Safe Torque-Off (STO): Integrated SIL 2-rated safety function supports machine safety compliance without external safety relays.
6. Energy Recovery: Regenerative braking capability feeds energy back to the DC bus, reducing net power consumption in high-cycle applications.

Technical Specifications & Selection Guide

Selection Guide: The SP2403 is recommended for applications requiring 3-phase 380-480V input with advanced servo positioning. For lower voltage or single-phase requirements, consult our team for alternative Unidrive SP variants. Always verify encoder interface compatibility with your motor before ordering.
