Product Description:

The KSM02.1B-061C-35N-S1-HG0-ET-SD-D7-ES-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series 2. It combines a permanent-magnet motor, power electronics, and motion safety functions in one housing. This design simplifies cabling and reduces cabinet space in automated assembly, packaging, and material-handling cells. The integrated layout also shortens motor and feedback runs at the machine frame.

This unit uses a Hybrid Connector, so power, feedback, and fieldbus conductors terminate at one plug, reducing separate cable entries at the motor. Heat is removed solely by natural convection, eliminating the need for forced-air hardware. The drive section accepts a bus voltage of DC 750 V, matching common DC-link supplies in multi-axis machines. Position data is generated by a Hiperface encoder that relies on optical scanning of 128 signal periods etched on the code disk, and this supports fine velocity loops without external interpolation. The encoder channel is single-ended in design version 1, and the motor is built without a holding brake, so static load retention must come from external mechanics or drive torque. Winding code 35 and motor length C correspond to the copper fill and stack height that tune torque to the 061 frame while keeping inertia moderate.

An external master controls the axis through Multi-Ethernet communications provided by the ET design option, allowing network selection between EtherNet/IP, PROFINET, EtherCAT, and Sercos III. Functional safety is handled by Safe Motion (with SBC); when activated, the integrated safety controller disables torque while maintaining position supervision. Rotor feedback is limited to single-turn operation, making it suitable for applications that re-home on startup. The drive uses the KSM basic performance level, includes a shaft seal to protect the interior, and features a plain shaft interface that mates directly with zero-backlash couplings. Frame dimension 061 fits compact conveyors and pick-and-place heads.
