Description
Product Overview
HNF01.2D-F240-R0026-A-480-NNNN (R911382794) is a 3-phase mains power line EMC filter designed for the Bosch Rexroth IndraDrive M modular servo drive system. It is installed upstream of HMV regenerative power supply units to suppress high-frequency noise and harmonic interference generated by the servo drives. It reduces conducted emissions on the AC mains line, helps the whole drive cabinet meet EMC standards, and mitigates leakage current caused by long shielded motor cables. It is perfectly matched with HMV / HMS series IndraDrive M drives for multi-axis motion control equipment.

Key Features
- Dedicated for IndraDrive M System: Optimized impedance matching for Rexroth HMV regenerative power supply units, works together with multi-axis HMS servo inverters.
- EMC Noise Suppression: Attenuates high-frequency switching noise generated by servo rectifiers and inverters, prevents drive interference from spreading to the factory power grid.
- Long Motor Cable Adaptation: Reduces leakage current from capacitive coupling of long shielded motor cables, prevents false drive alarms caused by cable capacitance.
- Robust Industrial Cabinet Design: Metal enclosure with internal high-performance filter components, stable performance under dynamic load fluctuation of multi-axis servo motion.
- Simple Installation & Wiring: Wall-mounted structure, 3-phase input/output terminals, convenient to integrate at the front end of HMV power supply.
- Harmonic and Surge Suppression: Limits transient grid disturbance generated during servo acceleration, deceleration and energy regeneration.
Applications
- CNC machine tools with IndraDrive M multi-axis servo system
- Metallurgical rolling lines and metal forming equipment
- Printing, paper and packaging high-speed production lines
- Automated gantry, pick-and-place and robotic multi-axis systems
- Heavy-duty material handling and lifting servo control systems
Installation & Maintenance Notes
- Execute lockout-tagout procedure before wiring. High voltage exists on the input and output terminals.
- Mount the filter as close as possible to the HMV power supply to minimize unfiltered cable length.
- Use low-impedance grounding; connect filter housing directly to cabinet protective earth.
- Separate filtered power cables from signal/encoder cables to avoid cross interference.
- Check terminal tightness regularly, inspect for overheating and dust accumulation.
- Select filter current rating according to the total input current of all connected HMV power supplies.
- Verify full part number match when replacing spare filter, voltage and current rating must be consistent.
FAQ
Q: What does HNF stand for? A: HNF = Hauptnetzfilter, German for main power line filter, the EMC mains filter for Rexroth IndraDrive series.
Q: Where is this filter installed in the IndraDrive M cabinet? A: It is installed on the 3-phase AC input side, between the mains breaker and HMV regenerative power supply.
