KSM02.1B-076C-35N-M1-HP0-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The Bosch Rexroth Indramat KSM02.1B-076C-35N-M1-HP0-ET-S3-D7-NN-FW is a motor-integrated servo drive in the KSM Motor Integrated Servo Drives series. Combining a servo motor and drive electronics within a single enclosure, it reduces cabinet wiring in distributed automation. The 076 frame size and length code C provide a mechanical envelope suitable for mid-range axes, while the integrated drive regulates torque and speed directly on the machine. In packaging, material-handling, and assembly stations, this compact unit provides decentralized motion with fieldbus connectivity.

Electrical power is supplied from a regulated bus at DC 750 V, which the internal inverter converts into three-phase output for the stator. Heat is removed through natural convection, allowing installation without forced-air ducts when ambient airflow is adequate. Feedback is handled through a Hiperface optical encoder that delivers 128 signal periods per mechanical revolution, allowing the controller to interpolate precise position data. Functional safety reaches the Safe Motion level without SBC, enabling controlled-stop and limited-speed modes within the drive. For higher-level control, the unit accepts commands through the Multi-Ethernet interface, which supports protocols such as EtherNet/IP, EtherCAT, and PROFINET.

The mechanical output uses a shaft with a keyway that transmits torque to pulleys or couplings without slipping. A dedicated shaft seal prevents coolant or lubricants from entering the bearing compartment, helping preserve service life when the motor is mounted in washdown or coolant-rich areas. Power, network, and sensor lines converge in a single hybrid connector, so only one cable set runs back to the supply module. The drive is supplied without a holding brake and uses winding code 35 for its electromagnetic design. It has a Basic performance level, design version 1, the standard option package, and series index 2.
