Product Description:

The KSM02.1B-061C-35N-M1-HP0-ET-S3-D7-TO-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat and delivered as part of the KSM Motor Integrated Servo Drives series. By combining drive electronics, power stage, and an AC synchronous motor in one housing, it streamlines installation inside packaging, material-handling, or assembly stations. The decentralized concept reduces cabinet wiring while still allowing coordinated motion through the integrated Multi-Ethernet channel, so the device serves as both actuator and axis controller in distributed automation architectures.

The unit is supplied from a DC 750 V bus and dissipates heat through natural convection, eliminating external fans. A single Hybrid Connector carries power, brake, and network lines, keeping external cabling consolidated. Communication with the higher-level controller uses the Multi-Ethernet interface, so the drive can be addressed over EtherNet/IP, PROFINET, or EtherCAT without additional hardware. Rotor position is captured by a Hiperface optical encoder that delivers 128 signal periods per mechanical revolution, and the sensor stores position as a Multi-turn absolute value, enabling startup without homing after power cycles. The assembly uses motor size 061 and length C, which fit the allowable current window of the KSM basic performance level.

Functional safety is embedded through the Safe Motion (without SBC) feature, which lets the drive execute safe torque off and safely limited speed when signaled from the fieldbus. Because the model is supplied without a holding brake, mechanical load retention must be handled externally. The output is a shaft with keyway, and a shaft seal blocks dust or fluid ingress along the journal. Series code 2 identifies the current technology platform for this line. Thermal capacity and magnetic design correspond to the winding code 35.
