KSM01.2B-071C-24N-M1-HG0-SE-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM01.2B-071C-24N-M1-HG0-SE-NN-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. This decentralized unit combines a motor, drive electronics, and a fieldbus interface in one enclosure, allowing it to mount directly on a machine axis and reduce cabinet wiring. In industrial automation systems, it provides closed-loop torque and speed regulation for conveyors, pick-and-place modules, and other motion tasks that benefit from distributed control. The product has an internal series code of 1 and belongs to the basic performance level for this platform.

Power enters through a hybrid connector that carries DC power and control lines, simplifying daisy-chain installation. The power stage accepts DC 750 V, making it compatible with modular bus supplies in multi-axis cells. Heat is removed by natural convection, so no fans are required and the enclosure can remain sealed. The platform uses frame size 071 with motor length C, while winding code 24 supports the motor's electrical characteristics within a compact housing. Command data travel over SERCOS 2 (RS-422), which supports deterministic communication cycles between the drive and controller. The unit uses the standard design option and design version 2 for its mechanical interfaces.

Feedback is handled through Hiperface communication with an optical encoder that generates 128 signal periods per revolution. The multi-turn absolute encoder reports position across multiple shaft revolutions without requiring a battery, allowing the controller to recover the axis position immediately after power-up. The drive is supplied without a holding brake, so an external mechanism must secure the load while the axis is idle or unpowered. A plain shaft with a shaft seal transmits torque while helping prevent contaminants from reaching the internal components. No safety technology is integrated into the drive. Power, feedback, and communication functions are contained within the motor-mounted enclosure, reducing the number of separate connections required between the axis and control cabinet.
