HDS04.1-W200N-HA40-01-FW
The HDS04.1-W200N-HA40-01-FW is a drive controller manufactured by Bosch Rexroth Indramat in the HDS Drive Controllers series. Designed for servo axes in modular automation racks, the unit regulates motor current and velocity as part of a multi-axis drive system used in machining centers, handling equipment, and transfer systems. It converts power from the supply stage into controlled phase currents so commanded motion can be translated into accurate axis response at the motor shaft. Its architecture also works with adjacent feedback interface cards for closed-loop operation without a separate external amplifier, which helps keep the control structure concentrated inside the rack.
The control section uses an analog command interface, allowing the unit to accept position or torque references from legacy CNC systems and other controls that output continuous signals. The power stage is rated for 200 A, which allows it to drive high-torque servo motors in demanding axis applications where strong acceleration or sustained load is required. Thermal management is provided by a built-in air blower that directs airflow across the heat sink instead of depending only on cabinet ventilation, helping the module remove losses generated by the power electronics. The drive is part of the DIAX04 platform and belongs to Line 04, which places it in the fourth design line of that family.
The unit is Version 1. It uses internal cooling with dedicated air ducting, so inlet and exhaust paths must remain unobstructed when the module is mounted in a crowded rack or beside other heat-producing components. This airflow arrangement supports stable temperature control in compact assemblies where several drives share the same enclosure. The controller is intended for applications that require accurate servo regulation while keeping the power and control functions in a single rack-mounted module, and its layout suits systems that organize power conversion, feedback handling, and axis control in neighboring sections.
