KSM02.1B-061C-61N-S1-HG0-ET-SD-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-S1-HG0-ET-SD-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining drive electronics and an AC servo motor in one housing, the unit mounts close to the machine mechanics and reduces cabinet wiring. It controls a single axis in packaging, material-handling, or assembly stations, delivering regulated torque and speed where motion is required without a separate panel-mounted inverter.

The electrical section accepts a bus voltage of DC 750 V, allowing the drive to supply current without a local rectifier. Power, control, and feedback lines share a hybrid connector, which reduces the number of wiring points. Heat is removed by natural convection, so the unit does not require fan maintenance. The motor has size 061 and the longer C stack length. It uses winding code 61 and the Basic performance level for its continuous torque range. A plain shaft supports the use of clamp couplings, while a shaft seal protects the front bearing from contaminants. The assembly is supplied without a holding brake, so an external device must secure static loads when drive torque is unavailable. The product is Series 2 and design version 1, and it uses the Standard design option.

Position feedback uses a Hiperface link connected to an optical sensor that generates 128 signal periods per revolution. The system tracks angular position in single-turn mode, which is suitable when the axis is referenced at startup. Upstream controllers communicate through Multi-Ethernet, allowing the appropriate supported protocol to be selected in software. Integrated Safe Motion with SBC provides monitored stop and speed functions without requiring additional safety relays. The feedback arrangement provides the drive with rotor position data for closed-loop control of motor torque, speed, and axis movement.
