KSM02.1B-061C-35N-S1-HG0-ET-SD-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-S1-HG0-ET-SD-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. As a self-contained axis, it combines a permanent-magnet motor, power electronics, and control logic in one housing to simplify decentralized automation layouts on packaging lines, gantries, and handling systems. The unit is Series 2 and Design Version 1, and it uses the standard design option. Its basic performance level is suitable for mid-range positioning tasks, while the integrated configuration reduces the amount of equipment required in a central control cabinet.

The drive receives power from a common DC bus at DC 750 V, allowing it to share regenerated energy with other axes without additional power supplies. A single hybrid connector carries DC power, safety I/O, and feedback lines, reducing cabinet wiring. Heat is removed by natural convection, so the mounting area must allow free air circulation rather than rely on fans. Rotor position is measured through a Hiperface optical encoder that delivers 128 signal periods per revolution, supporting accurate commutation and short-cycle movements. The motor has a size of 061 and a length of C, while winding code 35 provides a speed-torque curve suitable for moderate-inertia loads. The assembly is supplied without a holding brake, so stationary loads must be secured by drive torque or an external mechanism when required.

Machine control networks connect over Multi-Ethernet, allowing the drive to communicate through Sercos III, EtherNet/IP, or PROFINET. Integrated Safe Motion with SBC supports safe torque off, safe-limited functions, and safe brake control without external safety relays. Output torque is transferred through a plain shaft with a shaft seal, which helps prevent oil and dust from entering around the shaft opening. The encoder supplies absolute position data in a single-turn format, making a homing routine unnecessary after a power cycle when the axis remains within one mechanical revolution. The compact motor-integrated arrangement places motion control close to the driven mechanism, reducing long motor-cable runs and supporting decentralized machine layouts.
