Product Description:

The KSM02.1B-071C-35N-M1-HG0-ET-SD-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining power electronics with a synchronous motor in one enclosure, the unit streamlines decentralized automation where compact axes must be positioned and synchronized without a cabinet-mounted amplifier. This layout reduces the amount of separate hardware required near the machine and keeps the drive package close to the moving axis. It is built as design version 1, uses the Standard design option, and belongs to Series 2 with a Basic performance level.

Electrical energy is supplied over DC 750 V, allowing this device to share a common DC bus with other drives in linked motion systems. Heat leaves the housing through natural convection, eliminating additional fans or coolant lines and keeping the installation simpler. A single Hybrid Connector carries power, feedback, and safety conductors in one connection, which helps reduce cable routing complexity at the axis. Command data travels via Multi-Ethernet, so the same hardware can operate on EtherNet/IP, PROFINET, or EtherCAT. Integrated Safe Motion (with SBC) disables torque through certified circuitry for safety-related stopping functions. The motor uses size 071 with length C, and winding code 35 sets its electromagnetic characteristics.

Rotor position feedback is produced by a Hiperface optical encoder that generates 128 signal periods per revolution and stores multi-turn absolute data, so the axis does not need homing after power loss. This feedback arrangement supports accurate position tracking during restart and during normal closed-loop operation. A plain shaft couples directly to gears or belt pulleys, and a shaft seal is fitted for splash protection in typical machine environments. The drive is supplied without a holding brake, so load holding must be provided electrically or by an external lock when power is removed.
