Product Description:

The KSM02.1B-071C-35N-S3-HP2-ET-NN-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By embedding power electronics and control in the motor housing, the unit simplifies installation on decentralized machine axes and supplies torque, position, and speed control for automated handling, packaging, and assembly lines. It operates from a shared DC bus and exchanges real-time data with higher-level controllers to coordinate motion within industrial cells.

A Hybrid Connector carries power, feedback, and network signals through a single plug. Internal electronics are cooled by natural convection, so airflow around the housing is required. The drive draws energy from a shared DC 750 V bus. Motion commands and diagnostics are exchanged over Multi-Ethernet, allowing the same hardware to join EtherNet/IP, PROFINET, or EtherCAT topologies without extra modules. Rotor position is monitored through a Hiperface interface, and the single-turn encoder provides 16 signal periods per mechanical revolution. Factory settings correspond to winding code 35, design version 1, the Standard option set, and hardware series 2.

The electrically released holding brake engages when control power is removed and operates on DC 24 V during normal use, securing vertical or indexing loads. Output torque is transmitted through a shaft with a keyway, and a shaft seal helps prevent lubricant egress and contaminant ingress. The motor has size 071 with length code C, giving a compact profile suitable for mid-range applications without external gearboxes. Encoder sensing uses capacitive technology, which withstands vibration and temperature drift while maintaining resolution. The unit has a basic performance level and no integrated safety technology.
