KSM02.1B-061C-61N-M1-HG2-ET-SD-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M1-HG2-ET-SD-D7-NN-FW is produced by Bosch Rexroth Indramat as a member of the KSM Motor Integrated Servo Drives series. This compact servo unit integrates a synchronous motor, power electronics, and a fieldbus interface inside one housing, allowing it to be mounted directly on machinery without a separate cabinet. In decentralized automation systems, it actuates positioning axes and speed-controlled transport lines while reducing wiring and panel space.

The drive's power stage is designed for a bus supply of DC 750 V, a level that matches common IndraDrive power supplies and limits conductor current. Command and diagnostic packets reach the module over Multi-Ethernet, allowing it to operate with PROFINET, EtherNet/IP, or EtherCAT through protocol configuration. Rotor position is measured through a Hiperface interface that links the optical encoder to the control board. The encoder provides 128 signal periods, allowing fine interpolation for smooth velocity control. For vertical axes or load-holding tasks, the integrated brake is electrically released, so spring force clamps the shaft whenever the control supply is absent.

Thermal management relies on natural convection, eliminating fans and reducing the number of maintenance points. Power, safety, and feedback lines share a single hybrid connector, which simplifies routing through drag chains. Certified motion functions are available because the drive incorporates Safe Motion with SBC, enabling safe stopping and limited-speed monitoring inside the housing. The brake coil operates from DC 24 V supplied by the auxiliary line. The motor has a size of 061, length code C, and winding code 61. A plain shaft with a shaft seal helps prevent lubricant from escaping and contaminants from entering the housing. The unit has the standard design option, Design Version 1, a basic performance level, and belongs to Series 2.
