HDS03.2-W075N-HS62-01-FW
The HDS03.2-W075N-HS62-01-FW drive controller is produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It manages three-phase power conversion and motion commands so that servo motors follow setpoints from higher-level automation equipment in CNC machines and material-handling axes. In operation, the unit converts electrical input into controlled motor current for accurate speed and position response during coordinated motion. This role makes it a core power and control stage for industrial axes that require repeatable movement under changing load conditions.
Control data enters the device through the SERCOS optical ring, which provides deterministic communication for synchronized velocity and position control. Within the DIAX04 family, the module shares a common backplane and parameter structure, allowing it to fit mixed-axis racks without additional wiring changes. The power stage can continuously supply 75 A, so connected conductors and protective devices must be sized for that current level. Heat from the IGBT bridge is removed by a built-in air blower, which eliminates the need for external ducting and helps preserve cabinet space. Real-time telegrams and diagnostics are exchanged through the command communication channel, so operating data and status information move through the same communication path.
The unit belongs to Line 03, which identifies its design line within the series. It is listed as Version 2, marking the assigned revision for this model. The module is part of the drive controller line used in multi-axis cabinets, where several axes can share the same optical ring while remaining individually addressed by the control system. These identification details distinguish the module from other current ranges and revisions in the same platform without changing its primary role as a rack-mounted servo drive controller.
