KSM02.1B-076C-35N-M1-HP2-ET-L3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M1-HP2-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining drive electronics with the servomotor, it simplifies decentralized axis control on production machines and machine-mounted robots. The unit has design version 1 and the standard design option. It serves as a compact motion module that provides closed-loop torque and position regulation in automated assembly, packaging, and material-handling equipment.

The drive operates from a DC 750 V supply fed through a hybrid connector, so power, signal, and safety lines share a single plug. Motion commands reach the controller through Multi-Ethernet, enabling direct connection to EtherNet/IP, PROFINET, or EtherCAT networks. An internal safety circuit provides Safe Torque Off (STO), which removes motor torque without disconnecting the main power supply. Heat is dissipated by natural convection, allowing installation outside a cabinet when ambient airflow is sufficient. A basic performance level identifies the unit's control capabilities. Winding code 35 matches the electrical characteristics of the stator to the drive electronics.

Rotor feedback is supplied through a Hiperface interface connected to an optical encoder with 128 signal periods. Its multi-turn absolute capability retains position information across power cycles, eliminating the need for homing after startup. Position holding on vertical axes is handled by an electrically released brake energized at DC 24 V, preventing shaft motion when the controller is disabled. The motor has a frame size of 076 and a length code of C, providing moderate torque density while keeping the assembly compact. Output torque is transmitted through a shaft with a keyway, and the shaft seal helps prevent coolant and particles from entering the motor. The Series 2 electronics support the integrated drive and motor functions within the decentralized motion system.
