Product Description:

Bosch Rexroth Indramat builds the KSM02.1B-061C-35N-M1-HG2-ET-SD-D7-NN-FW as part of the KSM Motor Integrated Servo Drives series. This motor-integrated drive unit combines a servo motor, power electronics, and communication hardware in one housing, allowing decentralized axis control in compact machines and conveyor modules. The unit follows design version 1, has a standard mechanical option, fits the 061 frame size with motor length C, and uses a plain shaft with a shaft seal. Its basic performance level is suited to applications where reliable positioning and moderate dynamic response are sufficient for packaging lines, small handling robots, or printing stations.

The drive is supplied from a high-energy bus at DC 750 V, so it can be linked directly to shared DC networks in multi-axis systems. Installation is simplified because a single Hybrid connector carries power, Ethernet, encoder, and brake wiring. Thermal dissipation relies on natural convection; no fans are required, which reduces noise and eliminates forced-air cooling hardware. Command and diagnostic data reach the device over Multi-Ethernet, enabling selection of PROFINET, EtherNet/IP, or EtherCAT through software rather than hardware changes. Position feedback is delivered through the Hiperface interface, allowing the integrated controller to exchange motion data with higher-level control functions.

An optical measuring system refines shaft position to 128 signal periods per mechanical revolution, and the encoder stores turns as a multi-turn absolute count so homing after power cycles is unnecessary. When the axis is idle, an electrically released brake engages at DC 24 V to hold loads without energizing the motor windings. Integrated safety technology provides Safe Motion (with SBC), allowing speed-related or position-related protective functions within the same drive package. This arrangement supports decentralized servo axes in modular automation cells where compact wiring and integrated holding capability are needed.
