Rexroth KSM02.1B-041C-42N-M1-HG2-ET-L3-D7-NN-FW: Introduction & Technical Specifications
Introduction
The Rexroth KSM02.1B-041C-42N-M1-HG2-ET-L3-D7-NN-FW (part number R911334434) is a motor-integrated servo drive from Bosch Rexroth’s IndraDrive Mi KSM series, integrating a synchronous servo motor, inverter, control electronics, and firmware into a single compact housingRexroth. It uses a hybrid cable for DC power and Multi-Ethernet communication, with natural convection cooling via the motor housing surfaceRexroth. Key features include Multi-Ethernet connectivity, absolute optical encoder feedback, Safe Torque Off (STO) safety function, IP65 protection, and a plain shaft with seal; it is ideal for precision motion control in packaging, material handling, and general automation, offering easy installation, reduced wiring, and reliable performance in harsh industrial environments.
