KSM02.1B-061C-61N-S1-HG0-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-S1-HG0-ET-S3-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining a servo motor and drive electronics in one housing, it simplifies installation for distributed motion axes in industrial automation cells. The unit has design version 1 and follows the Series 2 layout. A hybrid connector carries power, control signals, and network communications through a shared connection, reducing the amount of separate wiring required between the motor and control cabinet. The motor transfers torque through a plain shaft equipped with a shaft seal, which helps prevent particles from reaching the internal bearings.

The drive section operates from a DC 750 V bus, allowing several axes to use a common power supply and braking resistor. Command and diagnostic data pass through the Multi-Ethernet master communication interface, which supports multiple real-time Ethernet protocols without an additional communication module. Heat is removed by natural convection, eliminating the need for cooling fans or liquid circuits. Rotor position is measured through a Hiperface optical feedback interface that provides 128 signal periods per mechanical revolution. The encoder operates in single-turn mode, providing absolute position information within one shaft revolution. The motor is supplied without a holding brake, so an external clamp or drive-generated torque must retain a stationary load. Winding code 61 is paired with the length C stator stack to provide the electrical characteristics required by the integrated drive.

The integrated Safe Motion without SBC option supports controlled stopping and limited-speed functions but does not include Safe Brake Control. The 061 frame width provides a compact housing for gantries, indexing tables, packaging equipment, and light material-handling systems where installation space is limited. Its basic performance level supports moderate torque requirements without adding features intended for more demanding applications. The standard design option uses the regular mechanical arrangement for this model. Network-based control allows motion commands, operating status, and diagnostic information to be exchanged with the machine controller through the same communication architecture.
