Product Description:

The HDS04.1-W200N-HT16-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. It functions as the power and control stage for one axis in a DIAX04 automation rack, converting DC bus energy into precisely metered three-phase output for servo motors. By closing velocity and torque loops inside the unit, it supports fast, repeatable positioning in packaging lines, printing presses, and material-handling cells. This internal control structure helps the connected motor follow commanded motion profiles with stable response during acceleration, deceleration, and changing load conditions.

The controller exchanges setpoints and feedback through the fiber-optic SERCOS interface, allowing deterministic communication with higher-level PLCs and coordinated motion across the machine. Internal heat is removed by a built-in air blower, which keeps air moving across the heat sink without requiring external ducting. A continuous output capability of 200 A allows the unit to drive large motors, while short-duration demand is supported by energy stored in the common DC bus capacitors. This arrangement is useful in servo applications that need rapid current response and consistent axis behavior during frequent start-stop cycles.

Within the product line, the controller is assigned to Line 04 and Version 1. These identifiers place the unit in a specific design generation of the series. The module shares the rack-based format used by related power supplies, interface cards, and axis modules, which helps maintain orderly installation inside a multi-axis drive system. Its modular layout also supports serviceable cabinet organization because power conversion, communication, and motion control functions remain concentrated in a dedicated axis unit rather than being distributed across separate assemblies.
