KSM02.1B-061C-35N-M3-HP0-ET-L3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M3-HP0-ET-L3-D7-NN-FW is a motor-integrated servo drive from the Bosch Rexroth Indramat KSM Motor Integrated Servo Drives Series 2. By combining drive electronics with a synchronous motor in one housing, the unit provides decentralized positioning and speed control for conveyors, tooling axes, and handling modules. Its compact format reduces the amount of wiring routed to a central cabinet. The integrated control stage also allows direct communication with higher-level motion controllers in industrial automation cells.

Power, control, and feedback signals are routed through a single hybrid connector, simplifying installation on distributed machine frames. The inverter section accepts a 750 V DC supply that matches the common intermediate bus voltage used in modular Rexroth drive systems. Heat produced by the power stage is released through natural convection, so the drive does not require an external fan when installed with adequate airflow. Rotor position data are transmitted through a Hiperface interface, allowing the internal controller to obtain absolute position information at startup without a homing move. Motion commands and diagnostic data are exchanged through Multi-Ethernet communication, which supports configuration for EtherNet/IP, PROFINET, or EtherCAT without changes to the communication hardware. The motor has a size of 061, a C length code, and a winding code of 35. It is produced as design version 1 with a basic performance level. The drive has no holding brake, while a shaft seal helps limit the entry of dust and fluids at the output end.

Functional safety includes Safe Torque Off (STO), which allows an emergency-stop circuit to inhibit torque-producing power without disconnecting the control wiring. The encoder provides multi-turn absolute feedback, retaining position information across power cycles. Its encoder uses capacitive sensing and produces 16 signal periods per revolution for rotor position measurement. Output torque is transmitted through a shaft with a keyway, which supports keyed couplings and pulleys used in material-handling equipment. The standard design option follows the Series 2 KSM mechanical envelope for decentralized drive installations.
