Product Description:

The KSM02.1B-061C-35N-M1-HG2-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat and supplied under the KSM Motor Integrated Servo Drives series. By combining a size 061 permanent-magnet motor with drive electronics and fieldbus hardware inside a single housing, it delivers decentralized motion control without a separate cabinet-mounted inverter. The unit is used in industrial automation to position loads accurately, sequence axes, and monitor motion feedback while reducing machine wiring. It can be mounted close to the driven mechanism, which shortens cable runs between the motor and power electronics.

The drive operates from a DC 750 V intermediate circuit and routes power, logic signals, and brake leads through a single Hybrid Connector, so installation uses one main connection point. Heat generated by the inverter components is removed by natural convection, allowing cabinet-free mounting on moving axes without separate fan hardware. A spring-applied, electrically released holding brake engages automatically at power loss to secure the load. Command and diagnostic data reach the device through the integrated Multi-Ethernet interface, which supports several real-time Ethernet protocols without additional option cards. The unit uses the standard design option and a basic performance level for this model.

Precise rotor position is provided through the Hiperface feedback channel; the embedded encoder uses 128 signal periods per revolution with an optical scanning method for accurate interpolation. Because the sensor is a multi-turn absolute type, the drive retains position over full power cycles, which can eliminate a homing sequence at startup. The mechanical output uses a plain shaft with a shaft seal to limit the ingress of dust and spray during washdown procedures. The C-length stator and winding code 35 place the motor in a moderate-torque range for distributed machine axes that still require closed-loop control. That combination suits positioning, indexing, and synchronized transfer motions where compact drive placement is more important than a separate central amplifier.
