KSM Motor Integrated Servo Drives
The KSM02.1B-071C-35N-M1-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. By combining motor and drive electronics in one housing, the unit reduces cabinet wiring and shortens installation time in distributed automation architectures. It is intended to position tooling, conveyors, or auxiliary axes where decentralized drives simplify machine layouts and free space in the main control cabinet.
The drive operates from a bus voltage of DC 750 V, which allows energy sharing across multiple axes on the same DC link. Power, signal, and brake conductors enter through a single hybrid connector; this consolidation minimizes cable runs and eases maintenance. Heat generated by the electronics is removed through natural convection, eliminating the need for fans and permitting installation in environments that favor passive cooling. Command and diagnostic data are exchanged over Multi-Ethernet, so the device can join EtherNet/IP, PROFINET, or EtherCAT networks without hardware changes. Rotor feedback is processed with a Hiperface interface, and the optical encoder provides 128 signal periods per revolution, supplying high-resolution position data for tight velocity and position loops.
Absolute position over multiple revolutions is retained by the encoder’s multi-turn absolute design, supporting homing-free startups and quick recovery after power cycles. The mechanical frame corresponds to size 071, and the electromagnetic package follows winding code 35, establishing the torque-to-speed characteristic expected from this length C motor. A plain shaft with a factory-installed shaft seal guards against lubricant ingress, while the absence of a holding brake shifts static load-holding duties to the machine mechanics or control strategy. The unit ships without integrated safety technology, matching its Basic performance level for applications where external safety controllers handle functional safety tasks.
