Product Description:

The KSM02.1B-041C-42N-M1-HP0-ET-SD-D7-ES-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By merging drive electronics with the mechanical unit, it serves as a compact axis controller for packaging, handling, and assembly stations that benefit from decentralized installation. The product regulates motor torque, speed, and absolute position directly at the machine, which helps reduce cabinet space and simplifies field wiring. This integrated layout also reduces the number of separate components that must be mounted elsewhere in the system.

Electrical power is supplied through a single Hybrid Connector that combines DC-bus, control, and network conductors, which removes the need for separate power and feedback leads. The drive operates from a DC 750 V bus supplied by a central power unit, so the internal power stage is suited to common-bus installations. Heat is dissipated by natural convection, allowing the housing to be mounted without fans or liquid circuits. Position feedback is transmitted through the Hiperface interface, and the optical encoder delivers 128 signal periods for accurate interpolation in the control loop during speed and position regulation.

The encoder stores position as a multi-turn absolute value, so the axis can retain turn information after power loss and does not require a homing routine at startup. Integrated Safe Motion with SBC provides internal safety monitoring without external safety relays. The motor uses Motor Size 041, Motor Length C, and Winding Code 42. A shaft with keyway and an integral shaft seal help prevent slippage and fluid ingress, while the unit is supplied without a holding brake to save space on horizontal axes. The unit is Series 2 with design version 1, and the external master communication option supports Multi-Ethernet protocols for real-time fieldbus integration.
