KSM02.1B-061C-35N-M1-HG0-ET-S3-D7-ES-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M1-HG0-ET-S3-D7-ES-FW is produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. This integrated servo axis combines the power electronics, feedback interface, and permanent-magnet motor in one enclosure, allowing it to mount directly on machinery without a separate cabinet drive. It is suitable for packaging, handling, and assembly stations where decentralized positioning reduces wiring and conserves control-panel space. The integrated arrangement also shortens the connections between the inverter and motor, which can simplify cable routing on machines with several coordinated axes.

The drive receives power from a 750 V DC bus that supports high peak torque and rapid acceleration. Power, feedback, and I/O wiring are consolidated in a single hybrid connector, simplifying installation through cable carriers and along machine frames. Heat is removed through natural convection, so the unit does not require cooling fans. Rotor position is returned through a Hiperface interface that provides optical, multi-turn absolute feedback with 128 signal periods per revolution. Command and diagnostic traffic use Multi-Ethernet communication, allowing PROFINET, EtherNet/IP, or SERCOS III to be selected for the control network. The electromagnetic package has a motor size of 061, a length code of C, and a winding code of 35. The electronics are Series 2, and the unit has design version 1.

A shaft seal protects the internal bearings from contaminants near the output end. Torque is transmitted through a plain shaft that is suitable for clamping couplings or compatible timing pulleys. Functional safety is provided by Safe Motion without SBC, which supports safe torque off and monitored motion functions. The Basic performance category is intended for applications with moderate continuous loads and standard dynamic requirements. The motor does not include a holding brake, so external mechanics or drive-generated torque must secure the axis when stationary. When power is removed, applications with suspended or gravity-loaded mechanisms require a separate means of preventing unintended movement.
