Product Description:

The KSM02.1B-041C-42N-M1-HP0-ET-NN-D7-NN-FW integrated servo drive is produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It unites a synchronous motor, power electronics, and a fieldbus interface inside one housing so that it can be mounted directly on machinery without a control cabinet. The drive section is Series 2, uses the standard design option, and is design version 1. With a motor size of 041 and length code C, the unit addresses light-to-medium load axes that require precise speed and position regulation in decentralized automation cells.

This model draws its intermediate-circuit power from a DC 750 V supply that is typically provided by an IndraDrive power supply module mounted elsewhere on the machine. Command data and diagnostics travel through the master interface, which supports Multi-Ethernet protocols so Profinet, EtherNet/IP, and EtherCAT controllers can access the same hardware. A single Hybrid Connector carries DC power, networking, and Safety I/O, which simplifies cable runs. Heat produced by the inverter stage is removed by natural convection; no fans are fitted, which reduces maintenance and allows flexible mounting orientation. Rotor position feedback is handled by a Hiperface encoder link, while winding code 42 identifies the electrical constants matched to the specified continuous current. The unit is supplied without a holding brake and includes a shaft seal. Functional safety must be provided by external machine measures because the drive is delivered without integrated safety technology.

The optical feedback assembly resolves the shaft into 128 signal periods per revolution and stores absolute position across power cycles with its multi-turn absolute memory. Its sensing method is optical, enabling fine interpolation for smooth velocity loops even at low speed. Mechanical power is transmitted through a shaft with a keyway, and the drive has a Basic performance level.
