Product Description:

The KSM02.1B-041C-42N-M1-HG0-ET-SD-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat and belongs to the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet servo motor, drive electronics, safety functions, and a network interface in one housing, the unit reduces cabinet load in decentralized automation. It is intended to position single axes or regulate torque directly on machinery such as pick-and-place arms, rotary tables, or packaging feeders, where quick wiring and a slim footprint are required.

Electrical power is supplied to the drive over a DC 750 V link that it shares with other axes on the machine, eliminating separate AC input stages. Mechanical dimensions follow Rexroth size code 041, and the active stack uses length code C, giving the torque reserve associated with midsize actuators. A single Hybrid Connector carries the DC bus, signals, and protective earth, so installation requires only one plug. Motion commands and diagnostics travel through the built-in Multi-Ethernet interface, allowing the same hardware to accept Sercos, EtherNet/IP, PROFINET, or EtherCAT masters without rewiring. Heat produced by the integrated inverter is removed through natural convection, so no blower or liquid circuit is necessary inside the housing.

The feedback chain relies on a Hiperface optical encoder that generates 128 signal periods per revolution and stores position across power cycles by means of a multi-turn absolute counter. This high-resolution data supports the integrated Safe Motion (with SBC) safety package, enabling controlled stop and safe limited speed without external sensors. Additional features include a plain shaft with a shaft seal, winding code 42 matched to the intended current range, a basic performance level, and no holding brake for applications that use mechanical clamps. The design option is standard, and the unit is series 2.
