KSM02.1B-061C-35N-M1-HG0-ET-SD-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M1-HG0-ET-SD-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a synchronous motor with an onboard drive controller, the unit provides decentralized axis control for packaging machines, material-handling lines, and other automated cells. It belongs to the second generation of KSM devices and serves as a compact motion module that receives DC bus power from a common supply. The integrated controller executes precise torque, speed, and position commands directly at the machine frame, reducing the amount of equipment required in a central control cabinet.

Its power stage operates from a 750 V DC supply, so a shared converter can run multiple drives without individual rectifiers. Command and diagnostic traffic are routed over Multi-Ethernet, allowing the unit to connect to EtherNet/IP, PROFINET, or EtherCAT networks. Rotor position is captured through a Hiperface optical encoder that provides 128 signal periods per mechanical revolution. The multi-turn absolute encoder retains position data across power cycles, supporting startups without a homing sequence. Thermal energy leaves the housing through natural convection, eliminating forced-air components and reducing enclosure noise. The unit is delivered without a holding brake, so static load retention must come from external mechanics or drive torque.

Field wiring enters through a single hybrid connector that carries DC bus power, logic power, and motor feedback through one plug, reducing cabinet wiring complexity. Functional safety is provided by Safe Motion with SBC, enabling safe torque off and safely limited speed functions. The drive uses a size 061 stator with motor length C and winding code 35, providing the torque characteristics required for basic-level applications. A plain shaft with a shaft seal supports gearhead or pulley attachment while maintaining ingress protection at the output end. The unit uses the standard design option, design version 1, and Basic performance level.
