Product Description:

Bosch Rexroth Indramat produces the KSM02.1B-061C-35N-M1-HP2-ET-L3-D7-TO-FW as part of the KSM Motor Integrated Servo Drives series. This motor-integrated servo drive combines a synchronous servomotor, encoder, and drive electronics in one housing, which reduces cabinet wiring and helps keep the power stage close to the motor. It is intended for decentralized axis control in automated assembly cells and packaging stations, where DC power is supplied from a common bus and motion data is exchanged with Ethernet-based controllers. Because the inverter is mounted directly on the motor, the unit suits machine layouts where cabinet space is limited and cable runs need to stay short.

The drive operates from DC 750 V and uses a single Hybrid Connector that combines power conductors and fieldbus lines to simplify cable routing. This arrangement also reduces the number of separate cable entries required at the axis. Heat is removed by natural convection, so the unit can be mounted in sealed machine frames without added fans. Rotor feedback is transmitted through Hiperface, and the sine-cosine encoder provides 128 signal periods per mechanical revolution for accurate commutation and stable velocity control at low speed.

An optical scanning module inside the encoder supplies multi-turn absolute position data, so the axis can recover its position after a power cycle without a full reference run. The servomotor includes an electrically released holding brake that engages automatically when the 24 V control line is removed, helping hold vertical or suspended loads at standstill. Integrated Safe Torque Off (STO) circuitry disables torque production without interrupting diagnostic communication. A shaft with a keyway transmits torque by positive locking, and the Multi-Ethernet interface allows cyclic data exchange with EtherNet/IP, PROFINET, or EtherCAT networks.
