KSM02.1B-071C-10N-S1-HG0-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-10N-S1-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. This Series 2 device combines a synchronous motor with drive electronics and has design version 1 with the standard design option. It provides decentralized, cabinet-free axis control, allowing conveyor, packaging, or handling systems to place the drive directly on the machine and reduce panel wiring.

The drive accepts a supply rail of DC 750 V, enabling it to share a common high-voltage DC bus with other axes. Power, feedback, and fieldbus conductors enter through a single hybrid connector, which simplifies installation on distributed machines. Heat produced by the electronics is removed through natural convection. No fans are fitted, so the mounting position must permit vertical airflow around the housing. Position feedback is delivered over a Hiperface interface, and an optical reader detects the code disk. The encoder provides 128 signal periods per revolution for precise commutation. Its single-turn design provides an absolute angular position within one mechanical revolution but does not track the number of completed revolutions. The plain shaft transmits torque without a keyway, while motor length C and the 071 frame provide moderate continuous torque for basic-performance applications.

Network access is handled by the Multi-Ethernet interface, which accommodates EtherNet/IP, PROFINET, and EtherCAT without hardware changes. Safety circuits are not onboard, and the unit is classified at the basic performance level. The drive operates without a holding brake, so vertical loads require an external holding mechanism when power is removed. An integrated shaft seal limits the entry of dust and fluid at the plain shaft exit.
