Product Description:

The KSM02.1B-071C-35N-M3-HG2-ET-L3-D7-NN-FW is produced by Bosch Rexroth Indramat and belongs to the KSM Motor Integrated Servo Drives series. This motor-integrated servo drive combines a servomotor, power stage, and fieldbus node in one housing so that motion control can be located directly on an axis. By eliminating a remote drive cabinet, it reduces cable runs and supports decentralized positioning tasks in assembly systems, packaging lines, and other automated machinery. Placing the electronics on the motor also shortens the path between the inverter and the winding, which helps keep the axis layout compact.

For power distribution, the drive connects to a DC bus rated at DC 750 V. Command data are exchanged through the Multi-Ethernet port, allowing the same hardware to participate on EtherNet/IP, PROFINET, or EtherCAT networks. Rotor position is measured by a Hiperface encoder that uses capacitive sensing and resolves motion into 16 signal periods per revolution while storing multiturn absolute position without batteries. When a protective circuit is engaged, the two-channel safety function Safe Torque Off (STO) removes gate signals from the inverter to prevent unintended shaft movement. This function interrupts torque production at the motor without requiring a separate mechanical disconnect in the drive section.

Thermal energy is dissipated by natural convection, so the housing contains no fans and can remain fully sealed during operation. All power, brake, and communication conductors are bundled in a single Hybrid Connector, which reduces cable clutter at the axis. The plain shaft is protected by a shaft seal, and the holding brake is electrically released with a clamping circuit rated at DC 24 V for load retention when the bus is off. The shaft seal helps protect the bearing area from dirt and light fluid exposure. Mechanical dimensions match motor size 071 with the compact C length, while winding code 35 corresponds to the motor's electrical winding. The unit uses the standard design option, design version 1, and Series 2 construction.
