Product Description:

Bosch Rexroth Indramat manufactures the KSM02.1B-071C-35N-M1-HG0-ET-S3-D7-NN-FW as part of the KSM Motor Integrated Servo Drives series. This self-contained unit merges a synchronous motor with drive electronics to deliver closed-loop axis control in distributed automation architectures. Integrating the drive and motor reduces cabinet wiring and enables direct mounting on machine frames, making the product suitable for modular conveyors, pick-and-place heads, and other motion tasks where decentralized intelligence shortens response paths. It draws energy from a shared DC bus and carries its own feedback and safety circuitry onboard.

The drive section is rated for DC 750 V, so installation requires a DC link of that magnitude from the central supply. Power, signal, and protective earth conductors run through a single Hybrid Connector, reducing wiring complexity. Heat is removed by natural convection, so the housing must remain unobstructed and no fan service is required. Control data reaches the unit through Multi-Ethernet, allowing EtherNet/IP, PROFINET, or EtherCAT to be selected during setup. Position feedback travels over Hiperface, and the optical encoder outputs 128 signal periods per revolution for accurate speed and torque control.

The motor has size 071 and motor length C, yielding a compact form that simplifies integration into tight axis spaces. A plain shaft and a factory-installed shaft seal allow coupling to pulleys or gearboxes while limiting oil or coolant ingress. Functional safeguarding is provided by the Safe Motion suite, which supports drive-based STO and SS1 but does not include safe brake control. Design version 1 combines series 2 electronics with winding code 35 for the basic performance level. Because the unit ships without a holding brake, stationary loads must be secured externally or by continuous servo torque. Its multi-turn absolute encoder retains position after power loss.
