Product Description:

The KSM02.1B-041C-42N-M3-HP0-ET-L3-D7-TO-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By placing power electronics, feedback evaluation, and fieldbus ports directly on the motor, it reduces cabinet wiring in distributed automation lines. This arrangement is useful in machine sections where shorter cable runs and decentralized axis control are preferred. The unit corresponds to motor size 041 with length code C, providing mid-range torque in a compact frame. The unit is design version 1 within series 2 and is used for axis control in pick-and-place stations, conveyors, and secondary packaging equipment.

Power is supplied through a Hybrid Connector, which routes the DC bus and logic conductors at DC 750 V. Heat is removed by natural convection, eliminating the need for fans or liquid jackets. For functional safety, the integrated controller includes Safe Torque Off (STO), which immediately disables torque when the safety circuit is opened. Position feedback uses a Hiperface interface with capacitive scanning, and it tracks 16 signal periods per mechanical turn while retaining position data without batteries. A shaft seal helps prevent coolant ingress, and the unit is supplied without a holding brake, so vertical axes need an external clamping device.

Networking is handled through the drive’s Multi-Ethernet port, which supports PROFINET, EtherNet/IP, Sercos over Ethernet, and other real-time protocols through a single receptacle. The encoder provides multi-turn absolute position information, allowing immediate position recovery after power cycling. The drive has Performance Level Basic, which suits applications that do not require expanded safety functions. Electrical characteristics are matched to winding code 42, allowing use on systems that share the same DC bus. This combination supports distributed motion control while keeping power, feedback, and network connections on the motor assembly.
