Product Description:
The HNF01.1A-M900-E0202 is a line-side mains filter manufactured by Bosch Rexroth Indramat for the HNF Mains Filters series. Installed ahead of a multi-axis servo system, the filter suppresses harmonic currents and attenuates high-frequency noise that could interfere with sensors, communication buses, or neighboring equipment. By presenting a controlled impedance to the public utility, it helps automation cells meet plant-wide electromagnetic compatibility rules and protects upstream circuit breakers from peak inrush currents drawn by drive rectifiers. This placement is especially useful in cabinets where several drives share the same incoming supply, because unwanted noise can be reduced before it spreads through the rest of the installation.
The filter has a nominal current of 202 A, allowing it to support high-power drive groups without excessive temperature rise. Electromagnetic behavior falls under category C3, and compliance with DIN EN 61800-3 places the unit in industrial environments that permit higher interference levels than residential areas. In the HNF Mains Filters series, differential and common-mode chokes are arranged ahead of the DC bus supply. This topology is used in Series 01 to limit conducted noise from regenerative inverters and help keep the supply waveform symmetrical. That arrangement also reduces high-frequency components that can travel along shared power conductors and affect nearby equipment.
One filter can condition the mains for up to 15 axes connected with an aggregate motor-cable length of 900 m while still meeting the stated emission limits. The model supplied as Design Version 1 uses the same mounting points as earlier prototypes. Its functional note of For feeding devices only means the filter is intended only for drive supply modules, so auxiliary loads such as control transformers and heaters require separate connections. This separates drive supply conditioning from accessory power distribution and keeps non-drive loads off the filtered path intended for the servo power section.
