KSM02.1B-076C-35N-S1-HP0-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-S1-HP0-ET-S3-D7-NN-FW is an integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. By combining power electronics with the 076-frame synchronous motor, it shortens cable runs and reduces cabinet requirements in modular machines. Intended for decentralized motion axes, the unit accepts power from a DC bus and delivers closed-loop torque and position control directly at the mechanical load.

The drive operates with a bus voltage of DC 750 V, allowing it to share energy with other axes on a common bus. Command and diagnostic data move through the Multi-Ethernet interface, so the same hardware supports EtherNet/IP, SERCOS over Ethernet, and PROFINET without additional cards. Rotor position feedback comes from a Hiperface encoder that provides 128 signal periods per revolution. Its optical scanning and single-turn format support accurate position interpolation. Heat is dissipated through natural convection, permitting installation on open frames without cooling fans. The unit is supplied without a holding brake, has design version 1 in Series 2, and provides the basic performance level for general automation.

Power, signal, and DC bus conductors terminate in a single hybrid connector, reducing wiring points during installation. Functional stop and speed-limited modes are handled by the integrated Safe Motion without SBC circuitry, eliminating the need for external contactors in category-oriented applications. A shaft with a keyway follows the DIN key convention and transmits torque, while an installed shaft seal helps retain lubricant. Stator winding code 35 matches the drive current limits, and the length C housing balances continuous torque with a compact depth. The unit uses the standard mechanical design option for the KSM02 generation.
