Key Functional Features

1. Comprehensive EMI & RFI Suppression
    
   Multi-stage LC filter topology eliminates switching noise from servo power circuits, preventing interference with adjacent sensors, encoders, HMI panels and communication bus cables; avoids signal distortion and false fault alarms on automation equipment.
2. Grid Power Quality Optimization
    
   Suppresses high-order harmonics injected back to factory power grids, reduces voltage fluctuation and protects upstream distribution breakers, transformers and power supply modules from servo drive distortion.
3. Perfect Matching with Lenze 9400 Single Drives
    
   Purpose-built for single-axis E94ASHE servo inverters, no extra wiring modification required; standardized terminal layout enables direct plug-and-play replacement during maintenance.
4. Robust Industrial Durability
    
   Metal shielded enclosure and high-temperature wound inductors deliver stable performance under long-term continuous shift production; conformal coated internal circuit boards optional for dusty, humid workshops.
5. Full EMC Compliance
    
   Meets EN 61800-5-1 adjustable speed drive EMC standards, eliminates additional external filtering equipment to simplify cabinet layout and reduce overall system cost.
