KSM02.1B-061C-61N-M1-HP2-ET-S3-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M1-HP2-ET-S3-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines power electronics, feedback devices, and a mechanical rotor in one housing. This integrated arrangement decentralizes motion control and reduces the amount of wiring required inside the control cabinet. The unit is suitable for automated packaging, material-handling, and assembly stations that require controlled torque, speed, and position.

Electrical power is supplied at DC 750 V, a common DC-bus level that supports dynamic torque commands. A single hybrid connector carries power, Ethernet, and safety lines, reducing the number of separate connections. Heat is dissipated through natural convection, allowing operation without fans or external airflow. Position feedback travels through the Hiperface interface, and the optical encoder provides 128 signal periods with multi-turn absolute position data. This feedback arrangement allows the controller to monitor rotor position across multiple revolutions. The spring-applied brake is electrically released, so it holds the load whenever the drive is disabled. The unit has design version 1, motor size 061, length code C, winding code 61, Basic performance, and a Series 2 platform. A shaft seal helps limit the entry of contaminants around the output interface.

Fieldbus control uses Multi-Ethernet, and the multi-Ethernet output coupling supports protocol selection among EtherNet/IP, PROFINET, and EtherCAT without physical interface changes. Integrated functional safety provides Safe Motion without SBC, allowing safe-stop and limited-speed monitoring functions to operate locally inside the drive. The brake coil is energized at DC 24 V, which is compatible with common machine control circuits. Output torque is transmitted through a shaft with a keyway, providing positive engagement with pulleys, gears, or rigid couplings. The keyed connection helps prevent relative rotation between the motor shaft and the attached mechanical component during acceleration or braking.
