KSM02.1B-061C-35N-M1-HG2-ET-SD-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M1-HG2-ET-SD-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a synchronous motor, encoder, power electronics, and network interface in one housing, the unit provides decentralized axis control for automated assembly lines, packaging stations, and material-handling cells. The assembly belongs to Series 2 of the platform and provides basic performance for applications that require compact installation and reduced cabinet wiring. Integrating the drive electronics with the motor also shortens the power and feedback connections between the control system and the machine axis.

The unit accepts a bus supply of DC 750 V, which feeds an integrated inverter that modulates phase current for the synchronous motor with winding code 35. Power, signal, and brake conductors pass through a single hybrid connector, simplifying cable routing at the machine. Heat generated by the electronics is removed through natural convection, so the housing requires sufficient clearance for unrestricted airflow. Rotor position is measured by a Hiperface optical encoder that supplies multi-turn absolute position data to the drive. Real-time commands are exchanged with higher-level controllers through the Multi-Ethernet interface, which supports common industrial Ethernet protocols. This communication arrangement allows motion commands, operating data, and diagnostic information to travel over the same network connection.

The drive includes an electrically released holding brake that clamps the shaft until the brake coil receives DC 24 V. The integrated Safe Motion with SBC functionality supports certified stopping and speed-monitoring functions without separate safety relays. Its feedback system produces 128 signal periods per mechanical revolution and retains absolute position information after power is removed. The motor uses a plain shaft with a fitted shaft seal, supporting direct coupling while helping protect the bearing area from contaminants. The C-length motor body is paired with frame size 061, providing a compact mechanical profile for decentralized installations. The unit has Design Version 1 and uses the standard build option for this model configuration.
