KSM02.1B-076C-35N-S1-HG0-ET-L3-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-S1-HG0-ET-L3-D7-TO-FW is produced by Bosch Rexroth Indramat for Series 2 of the KSM Motor Integrated Servo Drives. It combines servo motor mechanics and drive electronics in one enclosure, providing a decentralized motion axis that reduces cabinet space and wiring requirements. The assembly corresponds to design version 1 and has a basic performance level. Its motor section uses frame size 076 with length code C, providing a torque range suited to medium-duty stations in material-handling and assembly lines.

The integrated power stage draws from a 750 V DC link, allowing it to connect directly to a high-voltage bus distributed by IndraDrive supplies. Heat generated by the electronics is removed through natural convection. No fans are fitted, which simplifies maintenance and helps keep the housing sealed. Power, feedback, and network lines are combined in a hybrid connector, while the Multi-Ethernet output coupling provides access to Sercos III, EtherNet/IP, PROFINET, and EtherCAT through one port. Rotor position is sensed through a Hiperface interface. The optical encoder delivers 128 signal periods per revolution and uses a single-turn design, providing absolute position information for one mechanical rotation without batteries.

A machined plain shaft is protected by a factory-installed shaft seal, allowing installation in areas exposed to light washdown while helping prevent grease leakage. Functional safety is provided by Safe Torque Off (STO), which disables torque-producing power at the inverter output when the enable circuit opens. The drive section uses winding code 35 to match the electrical characteristics of the motor and drive. The unit is supplied without a holding brake, so vertical loads must be secured by an external brake or another suitable mechanical restraint when power is removed.
