KSM02.1B-061C-35N-S1-HG0-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-S1-HG0-ET-S3-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining the servo motor, encoder, drive electronics, and network interface in one enclosure, it simplifies installation on modular machinery and transfers torque directly to the load. The unit is intended for decentralized axes in industrial automation where a compact form factor and distributed power are required. Its integrated architecture reduces the amount of separate drive equipment that must be installed in a central control cabinet.

Drive power is supplied through a DC bus rated at DC 750 V, so the axis operates from a line-side inverter without requiring a local rectifier. Power, signal, and safety wiring share a single hybrid connector, reducing the number of cabinet terminations. Heat is removed passively through natural convection, eliminating the need for cooling fans. Feedback is transferred over the Hiperface interface, enabling electronic nameplate data to be exchanged between the motor and controller. Command and diagnostic traffic pass through Multi-Ethernet, allowing the unit to connect to SERCOS III, EtherNet/IP, or PROFINET networks with the appropriate configuration. The C-length stator and winding code 35 establish the motor's electrical characteristics, while the basic performance level and standard design option support midrange positioning tasks.

Position measurement relies on an optical sensing system that resolves the rotor position into 128 signal periods per revolution and reports absolute position through a single-turn code path. The drive transfers torque through a plain shaft with a shaft seal, which helps protect the motor from dust ingress, and the unit is supplied without a holding brake. The 061 frame size and design version 1 fit machinery envelopes that use KSM Series 2 electronics. Functional safety is provided by Safe Motion without SBC, allowing speed or position limits to be monitored through the control system without a safe brake control function.
