Product Description:

The KSM02.1B-071C-35N-M3-HP0-ET-L3-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. This standard configuration combines inverter electronics with a permanent-magnet motor in one housing, allowing decentralized motion control directly at the axis. It is design version 1 and belongs to series 2. In automated machinery, the unit handles closed-loop positioning and speed control while reducing cabinet wiring and saving panel space. Because the electronics are integrated with the motor, it also suits machine layouts where distributed drive placement helps shorten cable runs.

The drive operates from a single-cable supply of DC 750 V, and a Hybrid Connector carries power, feedback, braking, and safety connections through one plug. Motion commands are exchanged over Multi-Ethernet, which allows integration with several real-time network formats used in industrial control systems. Cooling is provided by natural convection, so the housing does not require an internal fan. The motor uses size code 071 with length C and winding code 35. Its output shaft has a keyway for torque transmission, and the shaft seal helps keep lubricant from migrating into the drive.

Position feedback is transmitted through a Hiperface interface connected to a multi-turn absolute encoder with 16 signal periods and capacitive sensing. This arrangement provides position data across multiple revolutions without battery support and helps maintain stable operation in areas with magnetic interference. The integrated safety function is Safe Torque Off (STO), which disables torque production without external contactors. The axis is supplied without a holding brake, making it suitable for applications that do not require mechanical holding at standstill.
