KSM02.1B-041C-42N-S1-HG2-ET-SD-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-041C-42N-S1-HG2-ET-SD-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. It combines a servo motor and inverter electronics in one enclosure to support decentralized motion control. This arrangement shortens cable runs and reduces the amount of equipment required in the control cabinet. The unit is suitable for positioning and speed-regulated axes in packaging machines, material-handling stations, pick-and-place equipment, and similar automated systems.

The drive operates from a DC 750 V supply link that can distribute power among compatible decentralized axes. A single hybrid connector carries power, logic, and communication signals, reducing the number of separate connections routed through the machine. Heat from the integrated inverter is removed by natural convection, so the unit does not require a fan or auxiliary liquid-cooling circuit. An electrically released holding brake secures the rotor when its dedicated 24 V circuit is switched off, helping prevent vertical or suspended loads from moving. Motion commands and status data are exchanged through Multi-Ethernet, which supports integration with EtherNet/IP, PROFINET, or EtherCAT networks. The motor has size 041, length code C, winding code 42, a standard design option, and design version 1 within the series 2 platform.

The feedback system uses a Hiperface interface with an optical sensor that produces 128 signal periods per revolution. Its single-turn absolute arrangement reports the rotor position within one mechanical revolution, allowing the controller to establish angular position after startup without tracking movement across multiple revolutions. Integrated Safe Motion with SBC supports internally monitored speed and standstill functions. Mechanical output is transferred through a plain shaft with a shaft seal, allowing direct connection to a suitable gear, pulley, or clamping coupling while limiting the entry of coolant and dust. The brake coil operates at 24 V DC, and the drive provides the Basic performance level. The compact integrated arrangement supports synchronized indexing and repetitive medium-dynamic motion without placing separate inverter hardware near the main cabinet power section.
