KSM02.1B-076C-35N-M1-HP2-ET-SD-D7-ES-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M1-HP2-ET-SD-D7-ES-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining a synchronous motor, drive electronics, and a fieldbus interface in one housing, the unit simplifies wiring and cabinet layouts in distributed automation systems. It is used to position axes or follow electronic gearing commands on packaging, assembly, and material-handling machines where decentralized motion control reduces panel heat and saves space.

The drive's power section accepts a bus voltage of DC 750 V, allowing it to share a common DC link with other converters on the machine. Communication with the controller is handled through the Multi-Ethernet interface included with the External Master Communication option. This interface supports EtherNet/IP, PROFINET, and EtherCAT communication. Rotor position is returned by a Hiperface encoder that uses 128 signal periods of optical scanning for each mechanical revolution, providing fine resolution for current, speed, and position control. Integrated Safe Motion with SBC enables safe torque off and speed monitoring without external relays. The hybrid connector combines power, control, and brake leads in one plug, reducing the number of separate cable connections.

The motor has size code 076 and length C, providing a compact footprint for torque class 2 drives. The output uses a shaft with a keyway, and a shaft seal limits the entry of dust or oil at the flange. Holding torque during power loss is provided by an electrically released brake. The brake coil is rated for 24 V DC and receives power through the hybrid connector. Heat from the integrated electronics is dissipated through natural convection, eliminating the need for a fan or liquid-cooling circuit. The drive has winding code 35, a Basic performance level, design version 1, and Series 2 identification.
