KSM01.2B-071C-35N-S1-HP0-SE-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM01.2B-071C-35N-S1-HP0-SE-NN-D7-NN-FW is a motor-integrated servo drive developed by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. This combined motor and controller unit mounts directly to the machine axis, eliminating the need for cabinet-mounted drives and reducing wiring in decentralized automation systems. It delivers regulated torque and speed for packaging, material-handling, and light assembly equipment where compact components and straightforward installation are required.

The unit operates from a bus voltage of DC 750 V, allowing it to share a common DC link with other axes on the machine. Heat produced by the electronics is removed through natural convection, so no fan or liquid cooling circuit is necessary. Power, control, and feedback travel through a single hybrid connector, which minimizes cable bulk. Motion commands and status data are exchanged over SERCOS 2 (RS-422), providing deterministic cycle times for synchronous multi-axis tasks. Rotor position feedback is supplied through the Hiperface interface, enabling the controller to receive position data after power-up.

The optical encoder provides 128 signal periods per revolution and is configured as a single-turn device, so it reports absolute position within one shaft revolution. The mechanical interface follows the IEC 71 mm frame. This size 071 motor has length code C and winding code 35, and the unit is Design Version 2. A shaft with a keyway transmits torque to pulleys or couplings, while an installed shaft seal helps prevent the entry of coolants or lubricants. The drive is supplied without a holding brake, so an external device must secure the load when holding force is required without motor power. The configuration does not include integrated safety technology. It has a Basic performance level and a standard thermal rating.
