Product Description:

The KSM02.1B-061C-35N-M1-HG2-ET-S3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. By combining a servo motor and drive electronics in a single housing, it minimizes cabinet space and wiring in distributed automation. The unit is installed for point-to-point positioning and coordinated motion on packaging lines, material-handling gantries, and similar tasks in industrial automation. Its integrated design also reduces electromagnetic interference loops because cable runs between the motor and inverter are eliminated.

Field installation is streamlined by a Hybrid Connector that carries power, feedback, and network wiring through one plug, reducing assembly time and the chance of miswiring. The housing relies on natural convection, so mounting must allow free airflow rather than require forced cooling hardware. Position feedback is handled through a Hiperface interface with an optical scanner that resolves 128 signal periods per motor revolution, providing multi-turn absolute data without homing cycles. Axis holding is secured by an electrically released brake energized at DC 24 V, preventing shaft movement during power-off or emergency stops. Command and diagnostic data travel over Multi-Ethernet, enabling the drive to operate on PROFINET, EtherNet/IP, or EtherCAT networks without hardware changes.

Inside the sealed enclosure, the drive electronics operate from a DC 750 V bus supplied by a central supply module, allowing daisy-chain distribution to multiple axes. Functional safety is addressed through Safe Motion (without SBC), which lets higher-level controls trigger STO or SS1 without separate safety relays. Mechanical power is transferred through a plain shaft with an integral shaft seal that blocks lubricant migration. Size 061 laminations, length code C, and winding code 35 place the unit in the Basic performance class, while design version 1 indicates the standard option in Series 2.
