KSM02.1B-076C-35N-M1-HG0-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M1-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. This drive-motor assembly combines power electronics, a permanent-magnet servomotor, and feedback hardware in a single enclosure, allowing motion axes to be placed directly on moving gantries or modular stations. It is intended to position light-to-medium loads with electric actuation in applications where cabinet space is limited and wiring complexity must be minimized.

The axis accepts a supply of DC 750 V from a shared DC bus, allowing the integrated inverter to generate the required phase currents without a local rectifier. All power, signal, and safety conductors enter through a hybrid connector, reducing the connector count and simplifying daisy-chain topologies. Heat produced by the inverter is removed through natural convection, so no fans are required. Rotor position is measured with a Hiperface optical encoder that delivers 128 signal periods per revolution and provides multi-turn absolute position data, giving the controller immediate position information at power-up. The unit comes without a holding brake, so an external mechanical restraint is required for a vertical axis that must remain stationary when power is off.

Communication with higher-level controllers is handled through the Multi-Ethernet interface, which supports multiple real-time fieldbuses through a single port. The unit has a Basic performance rating and does not include integrated safety technology. Mechanical output is provided by a plain shaft with a shaft seal, which helps protect the bearing area from contaminants. The electromagnetic package uses winding code 35, motor size 076, and motor length C. The unit also uses the standard design option, design version 1, and internal series number 2.
