Product Description:

The KSM02.1B-061C-35N-S3-HG0-ET-L3-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining drive electronics with a permanent-magnet motor, the unit supplies decentralized axis control for packaging, handling, and assembly equipment. This integrated layout reduces cabinet load and field wiring in industrial automation. It places the power stage directly at the machine axis, which helps keep distributed motion systems compact. This arrangement is common in modular machinery that uses multiple synchronized servo axes.

Electrically, the drive operates from a DC 750 V intermediate circuit, and its enclosure sheds heat by natural convection, so clear airflow around the fins is required. A single Hybrid Connector carries the power bus, encoder lines, and STO loop. Communication with PLCs is handled through Multi-Ethernet, allowing operation with EtherNet/IP, PROFINET, or EtherCAT. The motor has frame size 061 with length code C, which gives it a compact cylindrical form for tight installation spaces. Winding code 35 is used with the standard design option and design version 1 at a basic performance level. Because the unit is supplied without a holding brake, any vertical load must be secured by external means.

Feedback is generated by a Hiperface encoder that uses capacitive sensing to resist dust and vibration. Rotor position is resolved into 16 signal periods per electrical revolution, and the single-turn format suits applications that reference home after power-up. Drive-side functional safety is provided by Safe Torque Off (STO), which disables gate power when an emergency channel is triggered. The output uses a plain shaft, and a shaft seal helps prevent lubricant escape and contaminant ingress during washdown cleaning. Because position information is measured at the motor, the drive can support controlled motion without a separate external feedback device.
