Product Description:
The KSM02.1B-041C-42N-M3-HG2-ET-NN-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. By combining drive electronics with a permanent-magnet synchronous motor, it simplifies cabling on distributed automation axes and supports decentralized installation near the load. This arrangement places the power stage close to the machine axis and helps shorten motor and feedback routing. In motion systems, the unit provides torque generation, closed-loop control, and drive communication in a single housing, reducing panel space while maintaining dynamic positioning accuracy.
It accepts a bus supply of DC 750 V, allowing the internal inverter to modulate three-phase output without an onboard rectifier. Power, feedback, and fieldbus lines are consolidated through a single Hybrid Connector, so installation requires only one molded cable. Heat is removed by natural convection, so the housing must be mounted with free airflow rather than forced fans. Rotor position is monitored through a Hiperface interface that works with a capacitive encoder offering 16 signal periods of base resolution. Braking torque is provided by an electrically released holding brake that clamps the shaft when supply power is lost.
The encoder uses a Multi-turn absolute design, so shaft revolutions are retained after power cycles and startup does not require a reference move. The brake coil operates at DC 24 V, allowing the axis to remain secured from a low-voltage auxiliary supply. Network communication is handled through Multi-Ethernet, which supports EtherNet/IP, EtherCAT, PROFINET, or SERCOS over the same interface. Mechanical coupling uses a plain shaft with a factory-installed shaft seal, and the size 041 C-length motor with winding code 42 is suited to light to medium dynamic loads.
