HDS04.1-W200N-HT01-01-FW
The HDS04.1-W200N-HT01-01-FW is a modular axis drive unit produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It slides into a backplane alongside power supplies and amplifier cards to provide power conversion and closed-loop regulation for servo or spindle motors in machining centers, automated assembly lines, and material-handling stations. Acting between the PLC and the motor windings, the module conditions high-current output while processing feedback so commanded position and speed are maintained with tight control. Its rack-mounted format also allows the drive to operate as part of a larger multi-axis system without requiring a separate standalone enclosure for each motor axis.
The unit communicates through the SERCOS optical bus with deterministic 62.5 µs cycles. Its inverter section delivers 200 A continuously, allowing large motors to run without current foldback during peak loads. A built-in air blower channels cabinet air across the heat sink fins, so no external fan tray is required. As part of the DIAX04 controller family, the module uses the same card edge and encoder connectors found on other fourth-generation rack modules. It is classified as an HDS Drive Controller, so current, velocity, and position loops are closed in the device rather than in a remote control task.
The unit is part of Line 04, so cabinet mounting dimensions and backplane pinout remain consistent with other modules in that line. The command communication interface uses a standardized telegram set for control words instead of analog or parallel wiring. This arrangement keeps command exchange on the optical link and reduces the need for separate control wiring inside the rack. The drive is Version 1, indicating the initial release of this line. The remaining module functions stay focused on axis control, power conversion, and feedback handling within the shared drive system.
