KSM02.1B-061C-61N-M1-HP0-ET-L3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M1-HP0-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet synchronous motor, power stage, and local I/O inside one housing, it shortens cabinet wiring and places motion control directly on the machine axis. The device is intended for decentralized automation where compact drives execute positioning, speed, or torque tasks on conveyors, gantries, and packaging equipment without a full-size cabinet inverter.

Input energy is supplied by a common DC bus at DC 750 V, which supports high peak currents and regenerative exchange among linked axes. Thermal losses are removed through natural convection; the finned aluminum body dissipates heat without fans. An optical encoder supplies 128 signal periods per revolution and stores multi-turn data, enabling precise homing after power cycles. Integrated safety terminals implement Safe Torque Off (STO), so torque can be cut by a dual-channel command while control logic remains powered. Field installation is streamlined by a single hybrid connector that carries power, I/O, and Ethernet conductors in one plug. The drive has a C-length stator and winding code 61. It also has a basic performance level, design version 1, and Series 2 configuration.

Network integration is handled by Multi-Ethernet, allowing protocol selection such as EtherNet/IP, PROFINET, or EtherCAT through parameter settings alone. Position feedback travels over the Hiperface interface, so absolute position and temperature data reach the drive through the existing encoder cable. Mechanical coupling is provided by a shaft with a keyway that is protected by a factory-installed shaft seal for moderate splash environments. The compact 061 frame eases installation where space is limited. The drive is supplied without a holding brake, reducing inertial load on axes that demand rapid indexing.
