HDS03.1-W075N-HA40-01-FW
The HDS03.1-W075N-HA40-01-FW is a drive controller manufactured by Bosch Rexroth Indramat within the HDS Drive Controllers series. Designed for cabinet installation, the unit serves as the power and regulation stage for DIAX-compatible servo axes in automated equipment. It converts reference commands into controlled motor currents so position and velocity loops can respond accurately during indexing, positioning, and continuous-speed tasks. In a coordinated motion system, the controller sits between the power section and the connected motor, allowing the axis to track commanded movement with stable electrical control.
The controller accepts reference signals through an analog interface, allowing ±10 V setpoint transmission from PLCs or motion cards without additional fieldbus hardware. That input format supports straightforward use in systems that already generate conventional voltage commands for servo control. A continuous output capability of 75 A lets the module supply demanding servo or spindle loads while preserving current margin during acceleration and load changes. Cooling is provided by a built-in air blower, which moves cabinet air across the heat sink and removes the need for external ducting. As part of the DIAX04 platform, the unit shares bus bars and feedback connections with related modules in the same system.
The unit is part of Line 03, which indicates the design line used for its connector orientation and mechanical layout. It is released as Version 1, matching the initial revision for this controller type. Functionally, it is an HDS Drive Controller, so it operates as a dedicated power and control module rather than an integrated supply or I/O extender. It is intended to work with the supporting modules required in a DIAX cabinet instead of replacing them in a single housing. This classification separates it from cabinet components that handle mains input or auxiliary I/O, while keeping its role focused on regulated axis control.
