Product Description:
The KSM02.1B-041C-42N-S3-HP2-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the decentralized KSM Motor Integrated Servo Drives series. By combining drive electronics with a synchronous servomotor in one housing, it provides axis control without a separate cabinet amplifier, making it suitable for packaging, material-handling, and assembly cells that demand compact motion modules. The motor section has size 041 with length code C, and winding code 42 identifies the electromagnetic setup used in this unit. This integrated layout shortens the connection path between the inverter section and the motor, which helps keep distributed machine designs compact.
This drive accepts a supply bus of DC 750 V, and its power, feedback, and safety conductors are routed through a single Hybrid Connector, reducing wiring complexity on the machine frame. This arrangement is useful on compact machine sections where installation space is limited and cable routing must stay organized. Heat generated by the electronics is removed through natural convection, so no fans are needed when the unit is mounted in free air. Multi-protocol communication is provided through Multi-Ethernet, and the same port can be configured for EtherNet/IP, PROFINET, EtherCAT, or SERCOS III. Servo position is reported over the Hiperface interface. The drive uses the standard design option, design version 1, a basic performance level, and Series 2 of the platform.
The feedback system resolves rotor position into 16 signal periods per revolution by using a capacitive single-chip sensor, which offers high immunity to temperature changes and magnetic fields. A normally engaged, electrically released brake is supplied, and brake release requires DC 24 V. This helps the axis remain secured during a power interruption or other stop condition. Functional safety is provided by Safe Torque Off (STO), which removes drive energy without using contactors. A shaft seal is fitted to protect the bearings from splash ingress, and the output shaft uses a keyway for positive coupling to pulleys or gearboxes.
