KSM02.1B-076C-35N-M1-HP0-ET-L3-D7-ES-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M1-HP0-ET-L3-D7-ES-FW is produced by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. It combines servo-grade mechanics with embedded drive electronics, allowing an axis to be mounted directly on the machine without a separate control cabinet inverter. This decentralized architecture is intended for multi-axis production lines where shorter cable runs and reduced panel heat simplify installation.

The drive receives bus power from a high-energy DC link rated at DC 750 V. Power, signals, and safety I/O are combined in a hybrid connector, minimizing cabling while matching the Series 2 mechanical outline. Internal components are cooled by natural convection, so no fan is required. Command data reach the unit through Multi-Ethernet ports, which provide the external master communication option selected for Design Version 1. Position feedback is returned over the Hiperface encoder interface. The optical sensor inside the motor delivers 128 signal periods per revolution. The C-length stator uses winding code 35 and fits the 076 frame size, providing the basic performance level for this product type.

Functional safety is provided by the integrated Safe Torque Off (STO) circuit, which removes drive energy without mechanical intervention. The encoder uses a multi-turn absolute format to retain the shaft position across multiple revolutions, so homing is unnecessary after a power cycle. Because the model is supplied without a holding brake, an external load-holding device must be used when static torque is required. Output motion is transmitted through a shaft with a keyway, allowing positive engagement with a compatible coupling or driven component. A shaft seal helps prevent dust or coolant from entering around the output shaft. The integrated optical feedback supports closed-loop position and speed control directly within the decentralized drive. A single DC supply connection supports installation with other compatible axes on a shared power bus.
