KSM02.1B-041C-42N-M3-HP2-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-041C-42N-M3-HP2-ET-NN-D7-NN-FW is produced by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. This motor-integrated servo drive combines the servomotor, drive inverter, and fieldbus electronics in a single enclosure for decentralized installation. Frame size 041 and length code C establish its mechanical envelope, while design version 1 aligns its mounting points with other Series 2 units. Used in packaging, handling, and conveyor systems, the drive supplies closed-loop positioning and speed control without a separate cabinet-mounted controller.

The axis is powered from a DC 750 V bus link that is shared with other drives in the machine. All power, feedback, and brake circuits pass through a single hybrid connector, shortening wiring runs on articulating axes. Thermal energy is dissipated by natural convection, permitting fanless operation in enclosed machinery. Rotor position is measured through a Hiperface interface that works with a capacitive sensor, providing 16 signal periods per revolution. Because the feedback system is multi-turn absolute, the shaft position is retained after the main power is removed, simplifying homing sequences.

Control data and diagnostics travel over the Multi-Ethernet master communication port, which supports several real-time industrial Ethernet protocols selected through software settings. A spring-applied, electrically released brake energized at DC 24 V holds the shaft when the drive is disabled, helping prevent movement on vertical or suspended loads. Mechanical output is provided by a shaft with a keyway, and a shaft seal blocks lubricants or contaminants from entering the motor cavity. The unit uses the standard design option and basic performance class without integrated safety functions. Its decentralized layout reduces the need to route separate motor and feedback cables back to a central drive cabinet.
