Product Description:

The KSM02.1B-071C-35N-M1-HG2-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By integrating the motor, power stage, encoder, and network interface in one assembly, the unit provides decentralized axis control in industrial automation lines where panel space and wiring must be kept to a minimum. It is suited for conveyors, Cartesian robots, and form-fill-seal stations because closed-loop torque and speed regulation are placed directly on the machine. This arrangement shortens motor cable runs and helps simplify EMC compliance in distributed motion systems.

Power is supplied from a shared DC bus at DC 750 V, and the bus voltage and control signals pass through a single Hybrid Connector. Heat is removed by natural convection, so no fans are required in the IP-rated housing and airflow demands stay low around the axis. Position feedback uses a Hiperface optical encoder that generates 128 signal periods per revolution and supports multi-turn absolute tracking, which allows startup without a homing cycle after power-up. The unit also has an electrically released holding brake. It has motor size 071, length C, winding code 35, the standard design option, design version 1, a shaft seal, and the basic performance level used for series 2 devices.

Communication to the machine controller runs over Multi-Ethernet, so the same unit can join EtherNet/IP, PROFINET, or EtherCAT topologies without changing the physical drive hardware. Functional safety is integrated through the dedicated Safe Torque Off (STO) channel, which removes gate-drive energy without affecting the diagnostics bus and supports controlled machine shutdown behavior. The mechanical interface uses a plain shaft with no keyway, and the brake coil releases at 24 V DC when the machine is powered. The shaft seal also helps protect the output area when the drive is mounted close to moving machine elements.
