KSM02.1B-061C-35N-S1-HP0-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-S1-HP0-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet synchronous motor with an embedded drive controller, it brings decentralized axis control to packaging lines, pick-and-place gantries, and other machinery where control-cabinet space is limited. The unit connects directly to a shared DC bus and supplies regulated torque at the load, removing the need for separate drives and long feedback cables within the installation.

The drive operates from a bus voltage of 750 V DC, allowing direct connection to high-power inverters or regenerative supplies without an internal rectifier. Power, control, and feedback conductors merge into a single hybrid connector, which shortens wiring runs along the machine frame. Heat is removed solely through natural convection, and the absence of cooling fans reduces routine maintenance requirements. Position feedback enters the control loop over the Hiperface serial channel, while the optical encoder generates 128 signal periods per mechanical revolution for fine incremental resolution. The standard mechanical design is Version 1, and the housing uses length code C. The drive does not include a holding brake, so an external locking device is required when the load must remain stationary without power.

The single-turn measurement system provides a unique position within each mechanical revolution without tracking movement across multiple revolutions. Motion commands pass through Multi-Ethernet, which supports communication through EtherNet/IP, PROFINET, or Sercos III. Torque is transmitted through a shaft with a keyway, while an integral shaft seal helps prevent contaminants from reaching the front bearing. The motor has frame size 061 and length C, making its housing suitable for moderate-inertia loads. Winding code 35 sets the electrical characteristics needed for operation from the high-voltage DC bus. The drive has a basic performance profile and does not include integrated safety functions, so external devices must provide the required safety monitoring.
