KSM02.1B-061C-61N-M1-HP0-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M1-HP0-ET-S3-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 061-frame servo motor with drive electronics, the unit performs decentralized axis control directly on the machine. It is intended for applications where cabinet space is limited and efficient installation is needed because the power, feedback, and network interfaces are contained within a single housing. This arrangement reduces the amount of wiring routed between the control cabinet and the driven axis.

The drive operates from a shared bus voltage of DC 750 V and routes supply and signal lines through a hybrid connector, minimizing cable runs to the power source. Heat generated by the power section is removed through natural convection, so no forced-air components are involved. Position feedback is delivered through a Hiperface encoder that uses optical sensing to generate 128 signal periods per revolution. The encoder also provides multi-turn absolute position data, allowing the controller to retain the shaft position across multiple revolutions. The motor has a size of 061, a length of C, and a winding code of 61. The device is design version 1, uses the standard design option, and has Series 2 internal electronics. Its Basic performance level indicates baseline current and dynamic capabilities for the product range.

The integrated Multi-Ethernet communication interface allows the controller to operate on SERCOS, EtherNet/IP, PROFINET, or EtherCAT networks without changing its communication hardware. Functional safety is provided by the embedded Safe Motion option without SBC, which supports drive-based protective stops when external safety relays are connected. The mechanical output uses a shaft with a keyway for positive torque transfer to a coupling or gearbox. A shaft seal is fitted to help limit the entry of contaminants into the motor housing. The assembly is supplied without a holding brake, so an external mechanism or another suitable method must support static loads when motor torque is unavailable.
