Product Description:

The HDS04.1-W200N-HA18-01-FW is a modular drive control unit produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. It serves as the power and regulation stage for AC servo axes in machining equipment, material-handling systems, and automated assembly lines. When paired with compatible drive cards, the controller performs closed-loop current and velocity regulation while keeping the high-energy bus separate from low-level control electronics. In coordinated motion systems, it supplies the controlled motor current needed for speed changes, load response, and steady holding torque during operation. This layout helps organize multi-axis installations and keeps power conversion functions isolated from sensitive command circuitry.

The unit has a rated current of 200 A, which is the continuous armature current it can supply to connected motors without thermal derating under the stated operating conditions. Heat is removed by a built-in air blower that moves cabinet air across the heat sinks, so no external ducting is required for normal cooling. The airflow path is internal to the controller, which helps keep the module compact within cabinet installations. The controller is part of DIAX04, and it is assigned to Line 04. Those identifiers correspond to the module format used with related supply and interface cards in the same platform.

Command signals are handled through an analog interface, and the attached drive card receives torque or velocity references as ±10 V signals through the command communication interface. This arrangement suits machines that still use analog command architecture but need a high-current power stage in a modular rack. Because the command path remains analog, the controller can fit into existing machine designs that were built around voltage-based reference signals instead of digital fieldbus commands. The product is Version 1, indicating the first release of this controller type. Its signal path supports straightforward integration with matching analog motion components while keeping the command side separate from the power section.
