HDS03.1-W075N-HS55-01-FW
The HDS03.1-W075N-HS55-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Within an automation rack, it performs power conversion and closed-loop motion tasks for servo axes, acting as the link between the motion command system and the inverter stage that energizes motor windings. This arrangement allows the controller to regulate torque and speed while supporting coordinated axis movement in multi-drive machinery. It is suited for applications where servo motors must respond to command changes with stable current regulation and repeatable motion.
This unit exchanges real-time setpoints and feedback through the SERCOS interface, so synchronous data traffic can be shared across multiple drives on a single fiber-optic loop. The controller can deliver 75 A continuously, which sets the sustained output level for connected motors during acceleration and holding torque. A built-in air blower moves cabinet air across the heat sink, allowing the drive to maintain its rated load without external ducting. As part of the DIAX04 platform, the controller uses a standardized pinout and parameter structure that matches other modules in the same system. This helps the unit fit into multi-axis installations that rely on consistent electrical connections and control behavior.
The unit is part of Line 03 and is released as Version 1, indicating the product generation used for this controller type. It is classified as an HDS Drive Controller, so its diagnostics and operating behavior follow the expected functions of that controller class. Axis-specific parameters remain stored locally, so the drive keeps its operating data inside the module itself. The module format also supports installation in racks that already provide shared power distribution and the required cooling clearance.
