KSM02.1B-076C-35N-S1-HP0-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-S1-HP0-ET-NN-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines a servo motor, drive power stage, and feedback electronics in one housing, allowing decentralized axes to be added with minimal cabinet space and cabling. The unit draws energy from a common DC bus and provides position, velocity, and torque control directly at the machine frame. This arrangement supports installation in packaging, assembly, and material-handling systems where several coordinated axes are distributed throughout the machine.

The drive accepts a bus voltage of DC 750 V, matching the high-energy DC links used in modular multi-axis lines. Heat from the electronics is removed through natural convection, so the unit does not require a forced-air fan. Rotor position data are transmitted through the Hiperface interface, and the optical encoder provides 128 signal periods per revolution for accurate motion control. The motor has a frame size of 076, providing a midrange cross section suitable for pick-and-place equipment and small conveyors. It has a standard design, design version 1, and Basic performance level. Integrated safe-motion functions are not included, so any required functional safety must be provided by external equipment.

Field devices and higher-level PLCs communicate through the Multi-Ethernet interface, which supports EtherNet/IP, PROFINET, and EtherCAT communication. The stator uses winding code 35, pairing the motor length C stack with its corresponding electrical characteristics. Output torque is transmitted through a shaft with a keyway, providing positive engagement with a compatible coupling, pulley, or gearbox. A shaft seal limits the entry of moisture and contaminants around the output shaft. The encoder uses optical sensing and provides single-turn position feedback for rotor monitoring. A hybrid connector carries DC power, network communication, and I/O signals through one connection. The unit is supplied with no holding brake, so an external clamping device or another load-retention method is required when an axis must remain stationary without motor torque.
