KSM02.1B-076C-35N-S1-HG0-ET-NN-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-S1-HG0-ET-NN-D7-TO-FW belongs to the KSM Motor Integrated Servo Drives series produced by Bosch Rexroth Indramat. It combines a synchronous motor and servo inverter in one housing, allowing motion control electronics to be mounted directly on the machine axis. As a motor-integrated servo drive, it receives DC bus power, executes position control loops internally, and sends operating data to higher-level automation systems. This arrangement reduces cabinet wiring in packaging equipment, material-handling systems, and specialized assembly lines.

The unit operates from a 750 V DC supply and receives power and signals through a single hybrid connector, simplifying daisy-chain installations. Heat is removed by natural convection, so the enclosure does not require internal cooling fans. Position feedback is transmitted through a Hiperface interface and is generated by an optical encoder with 128 signal periods per revolution. Design version 1 includes the output coupling used for networked connections between compatible devices. Winding code 35 identifies the motor winding selected for the required torque and speed range. The unit has Basic performance and belongs to Series 2. It is supplied without a holding brake, so stationary loads must be retained by servo torque or an external mechanism when necessary.

Control communication and drive-to-drive connections use a Multi-Ethernet backbone that supports EtherNet/IP, PROFINET, and EtherCAT without additional option boards. The encoder has a single-turn design, providing absolute position information within one mechanical revolution. A plain shaft transfers torque to the connected machine, while an internal shaft seal helps prevent lubricant leakage and contaminant entry. The motor section uses motor size 076 and length code C, providing a compact frame for installations with limited space. The shaft does not include a holding brake, making the unit more appropriate for axes that do not require passive load retention. Integrated safety technology is not included, so a suitable external safety system is required when safe torque off or related functions are needed.
