KSM02.1B-061C-61N-S3-HP2-ET-L3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-S3-HP2-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines a servo motor and drive electronics in one housing, reducing the amount of wiring required for decentralized automation axes. The integrated design provides closed-loop motion control without requiring a separate cabinet-mounted inverter. This arrangement is suitable for packaging equipment, material-handling systems, and other machines with distributed motion axes.

The power stage accepts a supply of DC 750 V, allowing connection to a common intermediate-circuit bus in a multi-axis machine. Heat is removed through natural convection, and the absence of cooling fans reduces maintenance requirements and the movement of airborne contaminants. Motor, feedback, and power lines are routed through a single hybrid connector, reducing the number of separate connections required during installation. Position feedback uses a Hiperface interface that communicates absolute position data and provides 16 signal periods per revolution. The encoder uses a capacitive sensing principle, which is resistant to interference from magnetic materials, oil, and dust. An electrically released brake rated at DC 24 V holds vertical or suspended loads when bus power is removed.

Network traffic is handled through a Multi-Ethernet interface that can be configured for EtherNet/IP, EtherCAT, PROFINET, or SERCOS III communication. Functional safety is provided by Safe Torque Off (STO), which prevents the drive from producing motor torque without requiring the control electronics to be power-cycled. Mechanical power is transmitted through a shaft with a keyway, providing positive engagement with a compatible coupling or gearbox. A shaft seal helps prevent coolant and dust from entering around the output shaft. The motor has size 061, length code C, and winding code 61. It has a basic performance level, a standard design option, and design version 1. The encoder uses a single-turn format to report the absolute rotor position within one mechanical revolution.
