Product Description:

The KSM02.1B-071C-35N-M1-HP0-ET-L3-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat and supplied within the KSM Motor Integrated Servo Drives series. By combining a synchronous motor, power stage, and feedback electronics in one housing, the unit reduces cabinet wiring and supports decentralized motion axes on assembly lines, packaging machines, and material-handling stations. It accepts a shared DC bus, energizes its windings locally, and delivers position, speed, and torque control in real time while occupying the limited footprint available on moving carriages.

Electrical power is supplied through a bus line at DC 750 V, so drive stages on the network share one supply. The motor and sensor signals run through a single Hybrid Connector, simplifying installation and reducing cable bulk. Heat from the inverter is removed by natural convection, so no fan or liquid circuit is needed. Rotor position is reported over the Hiperface interface, and the encoder delivers 128 signal periods per mechanical revolution for smooth velocity regulation. The unit is Series 2 with design version 1 and uses the standard design option. Its winding code 35 and C-length stator balance thermal headroom against compact depth.

On the control side, the integrated drive exchanges cyclic data over the Multi-Ethernet interface, supporting PROFINET, EtherNet/IP, or EtherCAT without additional hardware. Functional safety is provided by Safe Torque Off (STO), which enables emergency shutdown of motor power without triggering an inverter trip. Because the actuator is supplied without a holding brake, any static load must be secured by external clamping or drive torque. Mechanical coupling is provided by a shaft with keyway, and a shaft seal is included to limit lubricant escape and particle ingress. With the 071 frame size and a basic performance level, the device supplies mid-range continuous torque while keeping mass low for gantry or robot mounting.
