Product Description:

The KSM02.1B-041C-42N-M1-HP0-ET-NN-D7-TO-FW is an integrated servo axis produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining the drive electronics, feedback, and motor into a single housing, it reduces cabinet space and wiring in decentralized automation cells. The unit operates as an axis module that receives power from a central DC bus and relays real-time position data to controllers, making it suitable for packaging machines, pick-and-place gantries, and material-handling stations where compact motion control is required. Its integrated layout also shortens the distance between the power stage and the motor section, which helps keep axis response direct and installation routing simple.

A shared DC 750 V bus feeds the power stage and logic, so no individual mains feed is required. Power, signal, and brake conductors arrive through a Hybrid Connector, allowing one cable to carry energy, feedback, and Ethernet connections. Heat is removed through natural convection, eliminating fans and coolant circuits and reducing the number of moving cooling parts. Rotor angle is measured over a Hiperface link that reads an optical scale of 128 signal periods, and the multi-turn absolute function retains position data through power cycles so the axis can return to controlled motion without a homing switch.

The communications interface uses Multi-Ethernet, which allows the node to connect to common industrial Ethernet networks through the selected coupling option. The motor section uses Motor Size 041 with length code C and a Winding Code 42 arrangement that matches the intended torque class for this frame. The motor has a shaft seal and a shaft with a keyway, allowing conventional couplings and positive torque transmission. The unit is version 1 with a basic performance level and is part of series 2. Because it has no holding brake and no integrated safety technology, static load retention and SIL functions must be provided by external equipment.
