Product Description:

The KSM02.1B-071C-35N-M1-HG0-ET-L3-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat and included in the KSM Motor Integrated Servo Drives series. By combining the motor, power electronics, and feedback system in one housing, the unit supports decentralized axis control in packaging machines, transfer systems, and other automated equipment. It provides closed-loop torque, speed, and position regulation directly at the axis, which helps reduce cabinet wiring and keeps the installation compact. This arrangement is suited to machines that require responsive motion control without a separate motor and drive layout.

Electrical power enters the unit at DC 750 V, allowing it to operate from a common DC bus shared by multiple axes. A single Hybrid Connector carries power, control, and Ethernet conductors, which reduces the number of separate cable connections at the machine. Heat is removed by natural convection, so the housing does not require an active fan when mounted with free vertical airflow. Position data is transmitted through a Hiperface link, and the optical encoder provides 128 signal periods per revolution for commutation and speed feedback. The integrated design keeps the electrical and feedback interfaces close to the motor, which supports stable signal transmission during motion.

Safety is provided by Safe Torque Off (STO), which removes torque-producing drive action during a stop command. The motor uses frame size 071 and has a plain shaft with a shaft seal, which helps protect the internal area from contamination. Communication is handled through Multi-Ethernet, and the integrated switch supports Sercos III, EtherNet/IP, EtherCAT, and PROFINET. The encoder stores multi-turn absolute position data, so the axis does not need a homing move after every power cycle. The unit is supplied without a holding brake, so any vertical load must be secured by external means.
