Bosch Rexroth HNF01.1A-M900-R0026-A-480-NNNN Servo Drive

HNF01.1A-M900-R0026-A-480-NNNN is a Bosch Rexroth IndraDrive mains filter from the HNF series, designed to be installed on the input side of IndraDrive servo drives to suppress conducted EMI and protect both the drive and the broader automation network. This three-phase filter targets 480 VAC input (3×, commonly used 400/480 V industrial supplies) and is specified for use in industrial environments where reducing high-frequency noise is essential for reliable motor control. It provides electromagnetic interference suppression in accordance with EMC guidelines and is documented as a standard accessory in Rexroth IndraDrive literature. The M900-R0026 variant denotes a specific revision within the HNF01.1A family, while the A-480-NNNN suffix indicates the 480 V version used with IndraDrive configurations. As a mains-filter component, it is intended to be paired with IndraDrive servo-drive setups to meet EMC requirements without affecting drive performance, making it a common choice for installations that prioritize EMI management in automation and manufacturing environments.
