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

The KSM02.1B-061C-61N-M1-HG2-ET-NN-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It is a Series 2, Design Version 1 unit with the Standard option, combining drive electronics, control interfaces, and a synchronous motor in one enclosure to reduce cabinet wiring in distributed automation layouts. The unit has a Basic performance level and does not include safety technology. It provides axis control in packaging, material-handling, and assembly lines that require compact, decentralized actuation.

Power arrives on the DC link at DC 750 V, enabling direct connection to centralized regenerative supplies. Process controllers exchange motion commands over Multi-Ethernet, allowing the device to operate as an EtherNet/IP, PROFINET, or EtherCAT node without hardware changes. A hybrid connector carries power and real-time signals, supporting single-cable installation. Heat is removed by natural convection, eliminating the need for forced airflow inside tight machine spaces. Rotor position is captured through a Hiperface optical encoder that delivers 128 signal periods per mechanical revolution, providing fine interpolation for smooth torque regulation. The motor has a frame size of 061 and a frame length of C, making it suitable for medium-torque point-of-load axes.

A spring-applied, electrically released brake engages when control power is lost. It is energized at DC 24 V to release the shaft during operation. Feedback retains the mechanical position because the encoder has multi-turn absolute capability, so a homing routine is not required after a stop. Mechanical output is delivered through a plain shaft, and a shaft seal helps prevent lubricant leakage and the entry of airborne contaminants. The internal stator uses winding code 61, which provides the electrical characteristics required for the 061 frame while keeping power losses within the motor's passive cooling capacity.
