KSM02.1B-061C-35N-M1-HP0-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M1-HP0-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. In this architecture, the power stage, position controller, I/O, and communication components are mounted on the motor itself, so the axis can be placed anywhere on the machine frame without a separate cabinet inverter. The unit delivers closed-loop speed and position regulation for packaging stations, pick-and-place gantries, and light assembly robots while minimizing wiring complexity and panel heat load.

Driven from a DC 750 V shared bus, the KSM02 axis can operate beside other decentralized drives without individual rectifiers. Power, feedback, and Ethernet connections share a single hybrid connector, streamlining field installation and service. Internal electronics dissipate heat through natural convection, so no cooling fans are required. Rotor position is captured by a Hiperface optical encoder that provides 128 signal periods per mechanical revolution, giving high interpolation fidelity for smooth velocity loops. Process commands and diagnostic data reach the controller through a Multi-Ethernet interface that supports EtherNet/IP, PROFINET, SERCOS III, and EtherCAT without hardware changes.

The electromechanical assembly has a frame size of 061 and length code C, supplying moderate inertia for medium-torque feed axes. Output torque is delivered through a shaft with a keyway, and a factory-installed seal blocks lubricant splashes and airborne particles from entering the bearing gap. The motion package has a basic performance level and is supplied without a holding brake, so external clamping is required for vertical loads when power is removed. The unit uses the standard design option in Series 2 and Design Version 1. Its winding code is 35, which balances copper loss against the thermal capacity of the aluminum stator housing.
