Product Description:

The KSM02.1B-041C-42N-S1-HG2-ET-SD-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat and assigned to the KSM Motor Integrated Servo Drives series. By embedding the drive electronics directly on the motor housing, it reduces cabinet space and shortens feedback and power runs in decentralized automation lines. This unit is in Series 2 and uses the basic performance level, making it suitable for packaging stations, small pick-and-place gantries, and similar axes. Its mechanical size is 041 with length C, and it uses the standard design option in design version 1.

Its power stage is supplied from a high-voltage DC bus of DC 750 V, allowing the device to share a common intermediary circuit with other drives. Network access to the controller is provided through the Multi-Ethernet interface, so EtherNet/IP, PROFINET, or EtherCAT controllers can communicate with it without hardware changes. Rotor position is captured by a Hiperface optical encoder that delivers 128 signal periods per revolution, and the single-turn format suits applications where homing after startup is acceptable. Braking torque is maintained by an electrically released holding brake that engages whenever the DC link is removed. Thermal management relies on natural convection, and winding code 42 identifies the electrical package selected for this frame.

For field wiring, power, signal, and brake conductors share a single Hybrid Connector, which reduces cable routing complexity at the machine. Functional safety is handled by the integrated Safe Motion (with SBC) package, enabling speed and stop monitoring without external relays. The mechanical interface uses a plain shaft with a shaft seal, which helps protect the shaft opening from dust and splash. When the application demands holding force, the brake receives DC 24 V from the control circuit to keep the rotor locked until motion is commanded.
