Product Description:

The KSM02.1B-041C-42N-M1-HP2-ET-NN-D7-NN-FW is manufactured by Bosch Rexroth Indramat and belongs to the KSM Motor Integrated Servo Drives series. It combines the motor, feedback system, power stage, and network interface in one compact housing for decentralized axis control in conveyor sections, pick-and-place heads, and small packaging stations. By eliminating long motor cables and separate cabinet drives, it simplifies installation and reduces electromagnetic emissions in industrial automation lines. The integrated layout also keeps the feedback path inside the unit, which supports consistent axis response during repetitive motion.

The drive is fed from a DC 750 V shared bus and routes power, control, and protective earth through a single Hybrid Connector. Command and diagnostic traffic move through Multi-Ethernet, and the embedded interface supports PROFINET, EtherNet/IP, and EtherCAT without additional hardware. Rotor position is transmitted through a Hiperface link to an Optical encoder that outputs 128 signal periods per mechanical turn. Because the encoder is multi-turn absolute, the control system retains position data after shutdown and restart. Winding code 42 matches the integrated inverter, and the unit is Series 2 with a basic performance level. It is supplied in the standard design option with design version 1.

The unit uses the size 041 frame with motor length C. A shaft with keyway transmits torque to the driven element, and a shaft seal helps reduce the entry of dust or splashed fluids at the output end. Heat is removed by natural convection, allowing operation without fans in upright or horizontal mounting positions. The holding brake is electrically released and operates on DC 24 V, so the axis can remain locked when the machine is idle. The unit does not include integrated safety technology, so external hardware must manage safe torque off or emergency-stop circuits.
