KSM02.1B-061C-35N-S1-HG2-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-S1-HG2-ET-S3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a synchronous servomotor with an embedded drive controller, the unit delivers decentralized axis control for packaging, material-handling, and assembly machines. It accepts high-voltage DC bus power and connects to a centralized motion system through its combined signal and power interface, allowing installation on moving machine sections without separate drive cabinets.

The integrated power stage operates from a nominal bus voltage of DC 750 V, enabling the axis to share energy with other drives on the same DC link. Thermal management relies on natural convection, so mounting must permit free airflow around the aluminum housing without forced fans. A single hybrid connector carries logic signals and motor power through one molded plug, reducing cabling on articulated robots or gantries. Network access is handled by Multi-Ethernet, which supports automatic selection among EtherNet/IP, PROFINET IO, EtherCAT, and SERCOS over Ethernet for compatibility with different controllers. The integrated arrangement reduces the number of separate connections required between the motor, drive electronics, and machine control system.

The axis-side safety functions include Safe Motion, providing drive-level monitoring of speed and position without an additional safety bus coupler. The holding brake is electrically released, producing mechanical clamping when control power is removed. It is energized by a DC 24 V supply delivered through the combined connection. Position feedback comes from a Hiperface optical encoder with 128 signal periods, delivering absolute single-turn position information to the embedded controller. A plain output shaft with a shaft seal retains lubricant, limits contaminant entry, and supports direct coupling to gearboxes. The motor has size 061, length C, winding code 35, and the standard design option.
