KSM02.1B-061C-61N-S1-HG0-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

Bosch Rexroth Indramat manufactures the KSM02.1B-061C-61N-S1-HG0-ET-NN-D7-NN-FW integrated servo drive. It belongs to the KSM Motor Integrated Servo Drives series and combines a permanent-magnet synchronous motor, position feedback, power electronics, and fieldbus interfaces in one enclosure. By mounting this device directly on machinery, equipment manufacturers can reduce cabinet wiring and place closed-loop motion control close to the load in packaging, assembly, and material-handling lines.

The drive accepts a supply of DC 750 V, a level that matches common shared-bus installations where multiple axes draw energy from one rectifier. Internal heat is removed by natural convection, so installation must allow unobstructed airflow without external fans. Power, signal, and safety conductors converge in a single hybrid connector, simplifying daisy-chain wiring between adjacent drives. Motion commands are exchanged through Multi-Ethernet, allowing the unit to join EtherNet/IP, EtherCAT, or PROFINET networks without hardware changes. Rotor position is reported over the Hiperface interface. The optical sensor delivers 128 signal periods per mechanical revolution, providing sufficient granularity for smooth servo regulation during interpolation tasks.

The mechanical section has a motor size of 061 and a C length code, balancing torque output and installation depth on small frames. A plain shaft mates directly with couplings or timing pulleys, and a shaft seal keeps lubricants from reaching the encoder cavity. The single-turn encoder reports absolute position within one revolution but relies on the controller for multi-turn counting. The unit is supplied without a holding brake, so stationary loads must be secured by external means or motor torque. Its winding code is 61, which matches the motor's magnetic parameters to the basic performance level. The unit also uses design version 1, generation 2 electronics, and a standard housing.
