Product Description:

The HDS04.2-W200N-HS94-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. It seats in a modular multi-axis rack to supply regulated three-phase output to industrial servo motors, translating motion commands from factory controllers into precise current profiles. By performing this closed-loop power conversion, the unit enables coordinated axis movement in automated machine tools, packaging equipment, and material-handling cells where accurate speed and torque control are required. The controller works within the rack power architecture rather than as a standalone inverter, and it can return regenerative energy to the bus during deceleration.

Primary communication relies on SERCOS, a fiber-optic interface that transmits cyclic setpoints and diagnostics with deterministic timing. Inside the DIAX04 family backplane, the module occupies one axis slot beside companion power modules. The current stage is rated for 200 A, allowing it to energize high-torque motors during rapid acceleration and sustained load changes. Thermal energy created by these currents is removed by a built-in air blower that draws cabinet air through the heat sink, so no external ducting is required. Deterministic timing helps keep multiple servo axes synchronized when a machine must accelerate, hold speed, and decelerate in a coordinated sequence.

Within the product line, the controller is classified as Line 04, a designation tied to its mechanical outline and connector arrangement. The unit is Version 2, which identifies the product revision used for this controller type. The control electronics manage current regulation and motion-related calculations, while the rack’s shared DC link handles bus power distribution between axes. This layout allows the controller to operate as one axis module in a coordinated multi-axis system without adding separate power conversion hardware at each motor connection.
