Product Description:

The KSM02.1B-061C-35N-M1-HP0-ET-L3-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It belongs to Series 2 and has a basic performance level. The unit combines a size 061 stator with a length C frame and winding code 35, placing the power electronics directly on the motor. This integration suits distributed motion axes where cabinet space is limited and the drive must mount close to the load. By placing the drive electronics at the motor, the system can support decentralized machine layouts with shorter motor leads and less cabinet hardware.

The drive operates from a DC 750 V supply bus and relies on natural convection rather than forced airflow, so it can be mounted without fans in clean machine zones. Power, signal, and safety lines are consolidated through a Hybrid Connector, reducing cable runs and keeping the external interface compact around the axis. Rotor position is reported through a Hiperface interface; its optical transducer provides 128 signal periods per mechanical revolution, and the multi-turn absolute design records turns without battery backup. A shaft seal is fitted to limit particle ingress into the bearing cavity, and the optical encoder design helps reduce sensitivity to electrical noise.

Functional safety is handled by the built-in Safe Torque Off (STO) circuit, which removes drive power without delay when a safety channel is tripped. Real-time control data reach the unit through the Multi-Ethernet master interface, allowing the device to operate on EtherNet/IP, PROFINET, or EtherCAT networks. Mechanical power is delivered through a shaft with a keyway, and the motor is supplied without a holding brake. Static load retention must be provided externally when the axis must remain fixed at standstill. The unit is design version 1.
