KSM01.2B-076C-35N-M1-HP0-SE-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM01.2B-076C-35N-M1-HP0-SE-NN-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines a drive inverter, feedback electronics, and a synchronous motor in one housing, reducing the amount of cabling required for distributed automation. The integrated arrangement also reduces the need for separate drive components in a central control cabinet. This model has a Basic performance level, motor size 076, and length code C, allowing it to fit compact machine frames while providing the continuous torque associated with the KSM platform.

The drive accepts a bus supply of DC 750 V through a single hybrid connector that carries power, control, and safety conductors. Heat is removed by natural convection, eliminating the need for cabinet fans or liquid-cooling equipment. Command and diagnostic data are transmitted through SERCOS 2 (RS-422), which supports cycle-synchronous communication with compatible Rexroth controllers. The unit has the standard design option, mechanical version 2, and internal series index 1. Its winding code is 35, matching the stator configuration to high-speed applications. The drive is supplied without a holding brake, so an external mechanism must secure vertical loads when power is removed. A shaft seal limits the entry of contaminants, while functional safety must be managed by the higher-level control system because the drive does not include integrated safety technology.

Position feedback is transmitted through a Hiperface interface connected to an encoder that provides 128 signal periods per revolution. The encoder uses optical sensing for accurate incremental position measurement during controlled motion. It also provides multi-turn absolute position tracking, allowing the drive to retain the shaft position across multiple revolutions. Mechanical power is transmitted through a shaft with a keyway, which provides positive engagement with pulleys, gearboxes, or rigid couplings. The combined motor and drive housing is suitable for decentralized axes in packaging machines, material-handling systems, and compact assembly equipment where installation space is limited.
