Product Description:

The KSM02.1B-061C-35N-M3-HG0-ET-L3-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat and assigned to the KSM Motor Integrated Servo Drives series. By embedding the drive electronics directly onto the motor frame, this unit eliminates separate cabinet-mounted amplifiers and reduces wiring on distributed automation cells. This arrangement also shortens the distance between the inverter and the motor, which helps keep axis layouts compact and reduces the number of external components around the machine. In high-speed pick-and-place stations or modular conveyors, it supplies closed-loop torque and position control directly at the axis, so motion can be located close to the work area without a remote servo amplifier.

Electrical energy is supplied through a DC 750 V bus that matches decentralized drive platforms. A single Hybrid Connector carries power and fieldbus lines, minimizing the number of cable entry points. Heat is removed by natural convection, allowing sealed mounting without fans. Communication uses Multi-Ethernet, so the drive can exchange data over Sercos, EtherNet/IP, PROFINET, or EtherCAT without hardware changes. Position feedback passes through a Hiperface interface that resolves the rotor to 16 signal periods. The unit is series 2 and design version 1, and it is supplied without a holding brake when the load can be held passively.

The feedback circuit uses a capacitive scanning method that resists dust and vibration, and it records shaft position as a Multi-turn absolute value, eliminating homing after power-up. For safety, the power stage can be disabled by Safe Torque Off (STO) logic while feedback remains available to the control system. Motion is delivered through a plain shaft protected by a shaft seal, which supports use where splash or light contamination may be present at the shaft exit. The 061 frame with C length and winding code 35 is paired with the basic performance level used for this axis family.
