Product Description:
The HNF01.1A-F240-R0026-A-480-NNNN is a three-phase mains filter from the HNF Mains Filters series produced by Bosch Rexroth Indramat. It serves as the input stage for multi-axis drive packages, where it limits conducted emissions and supports the safe return of regenerated energy to the supply network. By damping inverter switching harmonics, the device helps maintain electromagnetic compatibility in automated cells that rely on coordinated motion. This placement lets the filter condition incoming power before it reaches connected drive sections, helping reduce interference on nearby control wiring and supply lines. It is used where several servo axes or inverter channels operate from the same power structure.
It connects to a plant supply rated at 3 × AC 400–480 V with a -15% to +10% tolerance, so it accepts common low-voltage distribution used for industrial drives. The permissible network frequency of 50/60 Hz lets the same hardware operate in both European and North American installations. The enclosure protection level of IP20 means live parts are finger-safe, but the filter must be installed in a cabinet. Electromagnetic behavior is classified as C3 under DIN EN 61800-3, so it is intended for industrial power environments. The unit is released as design 1. These electrical and enclosure characteristics suit cabinet-based drive systems used on packaging, handling, and transfer equipment.
When used with inverters that return energy to the mains, the filter is intended for regenerative devices only, which helps prevent overvoltage on the DC bus during deceleration. A single unit can support systems with up to 6 axes, provided the total motor cable length does not exceed 240 m. This capacity is useful on coordinated motion platforms where several amplifiers share a common input section. It also works with shielded cables and cabinet bonding practices to reduce conducted interference in large gantry and transfer-line installations. This arrangement supports cleaner power integration across cabinets that combine multiple motion channels.
