KSM02.1B-061C-61N-M3-HP0-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M3-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 servomotor and drive electronics in one housing, it simplifies cabinet wiring and shortens feedback loops in distributed automation. The device controls rotary motion on packaging, handling, or small machining axes where compact installation space and decentralized power distribution are priorities.

This drive accepts a supply of DC 750 V, which is routed through a single hybrid connector carrying power, signals, and protective earth to reduce cable count. Heat generated by the embedded inverter is removed through natural convection, eliminating the need for forced-air fans and allowing installation directly on the machine. Winding code 61 indicates the stator impedance and torque constant used for the 061 frame. The assembly has the standard design option, version 1, and a basic performance level suitable for general-purpose positioning tasks. A shaft seal is fitted to limit the entry of contaminants at the output. The motor has a frame length of C, providing a compact housing for compatible gearheads and couplings.

Control data reach the drive over Multi-Ethernet, and the integrated interface supports common Ethernet-based fieldbuses without additional communication hardware. Position feedback is handled by a Hiperface encoder that delivers 16 signal periods per mechanical revolution and uses capacitive sensing for resistance to dust and oil. Its multi-turn absolute track records complete revolutions without battery backup, enabling immediate position retrieval after power is restored. Mechanical power is transferred through a shaft with a keyway, permitting positive engagement with pulleys or couplings. The unit is supplied without a holding brake, so an external mechanism must secure the load when drive power is removed. This arrangement is appropriate for axes where the coupled machine already provides a separate clamping or locking device.
