Product Description:

The KSM02.1B-061C-35N-M1-HG2-ET-SD-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By embedding the controller, power electronics, and feedback processing directly onto the 061-frame motor, it serves decentralized motion axes in industrial automation. The unit regulates position and torque on conveyors, filling machines, and pick-and-place stations where local mounting reduces cabinet load, shortens wiring runs, and supports modular machine layouts. Because the drive electronics are mounted on the motor, the axis can be placed closer to the driven mechanism and connected with fewer separate components.

The drive operates from a bus supply of DC 750 V, so the shared DC link can deliver high power while keeping current levels moderate. All power, feedback, and fieldbus signals enter through a single Hybrid Connector, minimizing cabling on moving carriages. Heat is removed by natural convection, allowing the housing to cool without fans or liquid circuits where forced airflow is unavailable. Position feedback is carried on a Hiperface interface, which transmits absolute position and diagnostic data over two differential channels. Inside the encoder, an optical disk provides 128 signal periods per mechanical revolution, giving the control loop fine angular resolution for precise velocity regulation.

Axis safety uses an electrically released holding brake that clamps the rotor whenever the 24 V supply is removed. During normal motion, the brake coil is energized by DC 24 V so the brake stays open and wear is reduced at standstill. Integrated Safe Motion (with SBC) functions allow speed and position monitoring without external relays. Communication with higher-level PLCs is routed through the Multi-Ethernet interface on the M1 controller board, and the network can be set for PROFINET, EtherNet/IP, or EtherCAT. The motor has a plain shaft with a shaft seal, motor length C, winding code 35, and design version 1.
