KSM02.1B-071C-35N-M1-HG0-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-35N-M1-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines power electronics, motor feedback, and an IEC-frame motor in one package, allowing decentralized motion control on compact machinery. The integrated arrangement reduces the need for cabinet-mounted inverters and extensive motor cabling in automated assembly stations and material-handling cells. Its direct connection to a shared intermediate circuit also supports distributed machine layouts with multiple coordinated axes.

The drive operates from a 750 V DC bus and dissipates heat through natural convection, eliminating the need for external fans. Power, signal, and brake conductors share a single hybrid connector, which reduces the number of separate cable connections required at the motor. Position feedback is transmitted through the Hiperface interface, and the encoder provides 128 signal periods during each mechanical revolution. The motor has size 071 and length C, providing a compact stator arrangement for installations with limited space. Its design version is 1, and its basic performance level is intended for standard motion-control functions. The motor has a plain shaft without a key, and a shaft seal helps protect the bearing area from contaminants. It is supplied without a holding brake, so stationary loads must be retained by drive torque or an external clamping device.

The optical encoder is a multi-turn absolute encoder that retains position information across power cycles, eliminating the need for a new homing routine after every shutdown. Command data and diagnostic information are exchanged through the Multi-Ethernet port, which supports compatible real-time Ethernet communication protocols. The plain output shaft accommodates direct connection to suitable clamping couplings, gears, or pulleys. The stator uses winding code 35 for its electrical configuration. The product has Series 2 construction and a standard design option. It does not include integrated safety technology, so machine safety functions must be provided through an external safety system.
