KSM02.1B-061C-61N-S1-HG2-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

Manufactured by Bosch Rexroth Indramat, the KSM02.1B-061C-61N-S1-HG2-ET-NN-D7-NN-FW belongs to the KSM Motor Integrated Servo Drives series. This product combines a servo motor, power stage, and control electronics in one housing, allowing it to be mounted directly on moving machine sections. Acting as a compact axis controller, it reduces cabinet space and shortens feedback paths in packaging lines, material-handling systems, and other automated equipment that benefits from decentralized motion control.

The unit draws energy from a shared bus rated at DC 750 V and routes power, signals, and Ethernet through a single hybrid connector. Heat is removed by natural convection, eliminating the need for cooling fans. Command data passes over Multi-Ethernet protocols, allowing connections through EtherNet/IP, PROFINET, or EtherCAT without hardware changes. The holding brake disengages when supplied with DC 24 V and engages automatically when that supply is removed, helping secure vertical loads during power-off conditions. The drive uses design version 1, has a Basic performance level, and belongs to Series 2. Its motor has size 061, length code C, and winding code 61. A plain shaft transfers torque to the connected machine, while an internal shaft seal helps prevent contaminants from reaching the motor bearings.

Position feedback uses a Hiperface interface connected to an optical sensor system. The encoder produces 128 signal periods per revolution, providing the controller with detailed rotor-position information for commutation and closed-loop motion control. Its single-turn encoder reports an absolute position within one mechanical revolution, after which the reported position range repeats. This feedback arrangement is suitable for linear actuators and rotary tables with limited travel because the controller can determine the shaft angle immediately after startup. The integrated electronics process the feedback close to the motor, reducing the distance traveled by sensitive position signals. Ethernet communication carries command and diagnostic data between the decentralized drive and the higher-level machine controller, while the combined power and communication connection reduces the number of separate cable routes required along the machine frame.
