Product Description:
The HNF01.1A-F240-R0065-A-480-NNNN is a three-phase mains filter produced by Bosch Rexroth Indramat for the HNF Mains Filters series. It is installed between the plant supply network and an IndraDrive or similar regenerative converter to suppress conducted noise and provide a controlled return path for energy fed back to the grid during braking events. By conditioning the line side of the drive package, the filter helps reduce electrical interference on the supply network and supports stable operation of upstream protection devices. This role makes it suitable for industrial automation systems that use regenerative drive technology and shared cabinet power distribution.
The enclosure has a protection rating of IP20, so the unit is finger-safe but should be mounted inside a control cabinet when dust, moisture, or other airborne contaminants are present. It accepts a nominal line voltage of 3 x AC 400 to 480 V at 50/60 Hz, with an allowable tolerance of -15% to +10% for common low-voltage industrial supply systems. The filter is intended for regenerative devices only, which means its choke and damping components are arranged to handle reverse power flow during deceleration without excessive heat buildup. Electromagnetic compatibility is classified as C3 under DIN EN 61800-3, making it appropriate for industrial environments that operate from their own transformer. In systems where the combined motor and feedback cable length reaches up to 240 m, the filter helps limit common-mode voltage peaks and supports reliable communication between the drive and connected motion components.
The unit is listed as Design version 1 and Series 01, which places it in the first release of this product line. Its rated throughput current and damping behavior support systems with up to 6 axes on one regenerative supply, so a compact multi-axis installation does not require a separate mains filter for each axis. This layout is useful in cabinets where several coordinated drives share one common line-side connection and braking energy is returned through the same supply path.
