KSM02.1B-041C-42N-M1-HG0-ET-S3-D7-ES-FW by Bosch Rexroth Indramat

The KSM02.1B-041C-42N-M1-HG0-ET-S3-D7-ES-FW is a motor-integrated servo drive from Bosch Rexroth Indramat that belongs to the KSM Motor Integrated Servo Drives series. It combines drive electronics with a synchronous motor in a single unit. This arrangement streamlines installation in automated assembly cells, gantry axes, and secondary packaging lines where decentralized motion control reduces cabinet space and cabling complexity.

This drive operates from a DC link of DC 750 V, so it can be supplied directly from IndraDrive power supplies without an intermediate transformer. Power, signal, and safety conductors share a single hybrid connector, which simplifies wiring and limits connection errors. Heat is removed through natural convection, eliminating the need for cooling fans. Rotor position is reported over the Hiperface interface by an optical encoder that delivers 128 signal periods per mechanical revolution, enabling fine velocity regulation at low speeds. The motor has a frame size of 041 and a length of C. It uses winding code 42 and is produced in design version 1 with a Basic performance level. The motor is supplied without a holding brake, and a shaft seal helps keep contaminants away from the bearings.

An external controller exchanges cyclic data with the drive through Multi-Ethernet, allowing communication over EtherNet/IP, PROFINET, EtherCAT, or SERCOS III networks. Position feedback remains available after power loss because the encoder is a multi-turn absolute encoder. Mechanical power is delivered through a plain shaft, which allows connection to inline gearboxes or belt-drive couplings. Integrated safety follows the Safe Motion without SBC concept, allowing functions such as STO and SS1 without an external safety relay. The unit uses Series 2 electronics and includes the External master communication option.
