Product Description:

The KSM02.1B-041C-42N-M1-HP2-ET-SD-D7-ES-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet motor, drive electronics, and a fieldbus interface in one housing, it simplifies decentralized automation tasks. The device operates in a 041 frame with a C-length stator, and the Basic performance level suits medium-duty packaging or material-handling axes powered from a common DC bus in factory cells.

The drive operates from DC 750 V, matching the intermediate circuit voltage used across multi-axis platforms. A single Hybrid Connector carries power conductors, feedback lines, and network signals, reducing wiring complexity. Heat generated by the inverter is removed through natural convection, so no fans or liquid loops are required. Rotor position is detected by a Hiperface optical encoder that provides 128 signal periods per mechanical turn. Its multi-turn absolute format eliminates homing after shutdown, and the optical sensing head is immune to magnetic interference. Winding code 42, Series 2 electronics, and Design Version 1 align the motor's electrical constants with compatible converters.

External master control is carried over Multi-Ethernet, allowing EtherNet/IP, PROFINET, or EtherCAT to be selected in software. Integrated safety functions meet the Safe Motion (with SBC) profile, so STO, SS1, and SS2 can be executed directly by the drive. The electrically released brake is energized at DC 24 V and engages when supply power is removed. Mechanical output is delivered through a shaft with a keyway, and a factory-fitted shaft seal protects the bearing pack against coolant spray. The integrated layout supports decentralized mounting on machine frames where cabinet space is limited.
