KSM02.1B-071C-24N-S1-HG0-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-24N-S1-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat and supplied within the KSM Motor Integrated Servo Drives series. The unit combines an inverter stage, feedback evaluation, and a synchronous servo motor so it can be mounted near the load rather than inside the cabinet. This architecture shortens cable runs, eases expansion, and delivers closed-loop positioning for conveyors, pick-and-place gantries, and other motion tasks in automated lines.

It draws power from a DC 750 V supply, so it connects to the common DC bus of modular drive systems without an intermediate rectifier. Heat generated by the electronics is removed through natural convection, allowing installation without fans when ambient airflow is available. Motor power and feedback conductors are grouped in a single hybrid connector, which reduces installation time and protects the connection against vibration. Command data and diagnostics travel over Multi-Ethernet, enabling the unit to join EtherNet/IP, PROFINET, or EtherCAT networks. Position feedback is resolved by an optical encoder that produces 128 signal periods per revolution, providing fine incremental resolution for velocity and position loops.

The drive body corresponds to motor size 071 and length code C, providing a compact envelope for medium-torque applications. A plain shaft simplifies coupling to gearheads or belt pulleys, and a shaft seal helps limit the ingress of dust or coolant. Because the unit is supplied without a holding brake, mechanical locking or drive torque must retain stationary loads. The unit comes without integrated safety technology, so external safety relays must be used where required. With winding code 24 and Series 2 electronics, this configuration is in the Basic performance tier and provides the standard dynamic range for general-purpose motion tasks.
