HDS04.2-W200N-HS54-01-FW
The HDS04.2-W200N-HS54-01-FW is a drive controller produced by Bosch Rexroth Indramat in the HDS Drive Controllers series. In a multi-axis cabinet, it serves as the power and control stage between a servo motor and higher-level PLC commands, converting control input into regulated current and voltage for dynamic axis motion. That role allows the controller to manage acceleration, deceleration, and steady-speed operation within coordinated machine sequences. The module is typically mounted on a backplane next to an HVE supply, where it becomes part of a modular drive system used in automation racks with a shared power structure.
Communication is handled through the fiber-optic SERCOS interface, which supports deterministic synchronization across multiple axes without extra signal wiring. The unit belongs to the DIAX04 platform, so it matches the electrical and mechanical format used by compatible supply, bus, and I/O modules in the same rack. Thermal management is provided by a built-in air blower that directs airflow across the heat sink fins, helping the controller operate in enclosures with ambient temperatures up to 45 °C. This internal airflow helps remove heat from the power electronics during sustained load. The power stage has a nominal output of 200 A, and the unit is Version 2.
The controller is part of Line 04, which places it within the same design line as other units for this voltage class. In the rack, it typically operates as a single-axis regulator connected to shared DC bus links and auxiliary encoder cards. It can be installed side by side with other identical modules, allowing regenerated energy from one axis to be used by another through the internal copper rails. This arrangement is common in systems where one supply module feeds several drive controllers from the same DC link, reducing the need for separate external braking assemblies in many operating conditions.
