Product Description:

The HNF01.1A-F240-R0094 mains filter is manufactured by Bosch Rexroth Indramat and belongs to the HNF Mains Filters series. Designed for regenerative multi-axis drive lines, the unit sits on the supply side of inverter stacks, where it limits conducted emissions and returns excess energy to the grid. It supports common bus arrangements in packaging, printing, and material-handling cells where several servo axes share one power interface. By filtering the incoming supply path, it helps reduce interference that could otherwise spread through shared plant power wiring.

This filter handles a nominal line current of 94 A, allowing it to feed several drives without thermal overload. It is rated for up to 6 axes, so one unit can serve a complete motion cell. The integrated reactors and capacitors support motor and DC-bus assemblies whose combined motor and encoder cables can reach 240 m without exceeding voltage-drop guidelines. Electromagnetic compatibility is classified as C3 in accordance with DIN EN 61800-3, which suits industrial environments with fixed installation and restricted public access. The line impedance and leakage current values are coordinated with Bosch Rexroth regenerative inverters so harmonic distortion stays below the acceptance curve during full-power operation. Its role on the supply side also makes it suitable for centralized power sections that feed several coordinated drive modules.

The filter is approved only for regenerative devices, so stored braking energy can flow back to the mains instead of being dissipated in braking resistors. The product is Design Version 1 and Series 01. These identifiers indicate the first hardware generation in this product line. Inside the control cabinet, the housing uses a standardized outline that keeps mounting-hole spacing and terminal placement consistent within the range. This operating restriction matches systems that return deceleration energy to the line rather than using resistor-based braking.
