Industrial Applications

1. CNC Machine Tool Precision Filtering

CNC machine tools relying on 400V servo motors between 600W and 3kW can suffer from high-frequency electromagnetic noise, potentially causing erratic axis positioning. Utilizing the R88A-FI1S309-SE RFI filter on the 3-phase power line suppresses this interference, stabilizing the control signal for precision multi-axis movements.

Problem Solved

Eliminates conducted EMI/RFI noise from the main power feed that could corrupt servo positioning loops and lead to machining deviations.
