KSM02.1B-061C-35N-M1-HP2-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M1-HP2-ET-S3-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines drive electronics, motion control, and a 061-frame motor with length code C in one enclosure, allowing decentralized axes to be installed without enlarging control cabinets. The unit provides closed-loop motion for packaging, material-handling, and assembly equipment that requires a compact drive and motor arrangement.

The drive operates from a DC 750 V power bus, allowing direct connection to compatible Rexroth regenerative supply systems. Command, parameter, and diagnostic data are exchanged through a Multi-Ethernet interface, which supports multiple industrial Ethernet protocols without changes to the installed communication hardware. Rotor position is measured by a Hiperface optical encoder that produces 128 signal periods per revolution and retains multi-turn absolute position data after shutdown. Heat is dissipated through natural convection, so the housing does not require fans or external air ducts. An integrated electrically released holding brake secures vertical loads after motor power is removed. Winding code 35 establishes the applicable electrical characteristics, while the unit has a Basic performance level, a Standard design option, design version 1, and a Series 2 configuration.

A DC 24 V control supply powers the brake coil and internal control circuits, allowing motor power to be removed while monitoring functions remain active. Functional safety is provided by Safe Motion without SBC, which supports speed and position supervision without Safe Brake Control. Power, network, encoder, and brake conductors connect through a single hybrid connector, reducing the number of separate cable interfaces required at the housing. The output shaft has a keyway for positive engagement with compatible couplings, and an installed shaft seal helps prevent contaminants from reaching the bearings. The integrated arrangement keeps the mounting footprint compact while providing the electrical, feedback, braking, and communication interfaces needed for a decentralized servo axis.
