KSM02.1B-071C-24N-M1-HP2-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-24N-M1-HP2-ET-S3-D7-NN-FW is a motor-integrated servo drive from the Bosch Rexroth Indramat KSM Motor Integrated Servo Drives series. It combines a synchronous motor, drive electronics, position feedback, and safety functions in one housing for decentralized automation. The unit can mount directly on machinery where cabinet space is limited, including packaging systems, material-handling equipment, and small assembly lines. Its basic performance level supports controlled motion without adding unnecessary functions. Safe Motion without SBC provides integrated safety functions while allowing power, feedback, and communication wiring to remain compact.

The drive operates from a bus supply of DC 750 V, allowing energy to be distributed through a common DC link in a modular machine. Power, signal, and brake conductors pass through a single hybrid connector, reducing the number of separate cable connections required at the housing. Heat is removed by natural convection, so the unit does not require a fan or liquid-cooling circuit. Position feedback uses a Hiperface interface, which transfers absolute multi-turn position data to the controller. Commands and diagnostic data travel through Multi-Ethernet ports that support integration with compatible industrial Ethernet networks. The drive includes an electrically released holding brake, winding code 24, and a standard design option for mid-range motion axes.

The optical encoder produces 128 signal periods per motor-shaft revolution, supporting smooth speed regulation and accurate position feedback at low speeds. Brake release requires DC 24 V from the machine's auxiliary supply, while the brake remains engaged when release power is removed. The motor has a frame size of 071 and a frame length of C, providing a compact mechanical envelope for direct connection to gearboxes, belt pulleys, or other driven components. Torque is transmitted through a shaft with a keyway, which provides positive engagement with a compatible coupling or hub. A shaft seal helps limit the entry of contaminants when the unit is installed outside a protective enclosure. The sealed connection arrangement also supports cable routing close to the machine frame without requiring a separate motor-feedback junction box.
