KSM02.1B-076C-35N-M1-HP2-ET-SD-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M1-HP2-ET-SD-D7-NN-FW is a motor-integrated servo drive in the KSM Motor Integrated Servo Drives series produced by Bosch Rexroth Indramat. By combining a synchronous servomotor with power electronics in one housing, it provides decentralized motion control for machines that share a common DC bus. The unit mounts directly on the machine frame, reducing cabinet space and shortening feedback, power, and network cabling. It is intended for indexing tables, packaging machines, and assembly cells that require precise torque, speed, and position control without separate drive modules.

Electrical integration centers on a hybrid connector that carries DC input, network signals, and brake power through one plug, simplifying installation. The drive accepts a bus voltage of 750 VDC, matching Rexroth supply modules used in multi-axis systems. Heat is removed by natural convection, so no fan maintenance is required when the motor operates within its thermal limits. Control data reach the onboard processor over Multi-Ethernet, allowing the use of EtherNet/IP, PROFINET, or EtherCAT without hardware changes. Position feedback enters through the Hiperface interface, and its optical multi-turn encoder provides 128 signal periods per revolution to support fine interpolation for tight velocity control. The unit has size 076, length C, and winding code 35. Its standard design version 1 maintains consistent mechanical dimensions across the series.

An electrically released brake holds the rotor when power is removed and operates with a 24 VDC supply. The drive supports Safe Motion with SBC functions, enabling certified safe torque off, Safe Stop 1, and speed monitoring without external relays. Mechanical power is transmitted through a shaft with a keyway, while a factory-installed shaft seal protects the bearing set against splashes and dust. The unit has a Basic performance level, and its single hybrid connection keeps auxiliary wiring compact.
