Product Description:

The KSM01.2B-041C-42N-M1-HG0-SE-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By merging drive electronics with the servo motor, it decentralizes motion control and frees panel space in assembly cells, material-handling gantries, and packaging lines. The unit taps the shared DC bus and mounts directly on the machine frame, providing position, speed, and torque regulation for mid-range automation duties that demand compact installation and reduced cabling. Because the inverter is mounted at the axis, the layout is well suited to distributed machine sections where long motor cable runs would be undesirable.

This drive accepts a bus supply of DC 750 V, allowing it to share regenerated energy with other axes on the same power rail. All power, feedback, and network conductors are combined in a single Hybrid Connector, which keeps the connection layout compact and easier to route. Heat is removed through natural convection, so no fans or liquid circuits are necessary. Rotor position is measured by a Hiperface optical encoder that yields 128 signal periods per revolution and preserves absolute angle across multiple turns through its Multi-turn absolute design. A shaft gasket keeps contaminants away from internal circuits, and the drive is supplied without a holding brake.

Command and diagnostic traffic travels over the SERCOS 2 (RS422) interface, delivering deterministic cycle times for coordinated axes and reliable cyclic communication with the higher-level control. Mechanical output leaves the housing through a plain shaft, making the device suitable for clamp couplings or timing pulleys on compact distributed axes. Electrical behavior follows Winding Code 42, while the motor uses size 041, length C, design version 2, and series 1. The included shaft seal supports installation in clean or lightly contaminated zones, and safety functions remain external because no internal safety technology is included.
