KSM02.1B-061C-35N-M1-HP2-ET-S3-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M1-HP2-ET-S3-D7-TO-FW is manufactured by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. It combines a permanent-magnet motor, drive inverter, and safety electronics within a frame size of 061, allowing complete motion axes to be mounted on robots, gantries, or conveyor zones without a separate drive cabinet. The integrated design shortens feedback paths and reduces the number of cables required for installation. Direct connection to a shared DC link supports compact, decentralized automation cells that use high-speed industrial communication networks.

The drive accepts a bus voltage of DC 750 V, which supplies power to the integrated inverter. A single hybrid connector carries power, control, and auxiliary lines, reducing the number of separate connections at the axis. Heat is removed by natural convection, so the finned aluminum housing requires adequate space for ambient airflow. Position feedback is generated by a Hiperface optical encoder that provides 128 signal periods per revolution and multi-turn absolute tracking, making the shaft position available immediately after power-up. The motor has length code C and winding code 35, which provide the electrical characteristics used for its basic performance level. The unit uses design version 1 and Series 2 electronics with Multi-Ethernet output coupling, allowing downstream drives to be connected in a daisy chain without separate network switches.

An electrically released brake rated at DC 24 V secures the shaft when power is removed. Integrated Safe Motion without SBC functions are processed locally and communicate through the master network protocol. Mechanical output is provided through a shaft with a keyway, which creates positive engagement with a compatible coupling or gearbox. A shaft seal protects the bearing area against the entry of contaminants and supports installation in protected industrial assemblies. The basic performance level is intended for standard point-to-point positioning tasks that do not require advanced safety redundancy.
