Product Description:

The HDS04.2-W200N-HS54-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat and supplied as part of the HDS Drive Controllers series. Installed in a multi-axis cabinet, it conditions incoming power and issues torque commands to connected servo and spindle motors, serving as the core of closed-loop motion control in machining centers, material-handling gantries, and similar automation equipment. By integrating power electronics, motion logic, and status diagnostics in a single housing, the unit reduces cabinet wiring and keeps the axis hardware concentrated in one module. In this role, it regulates the electrical output needed for precise speed and torque response on positioning axes as well as spindle applications.

Its command channel is SERCOS, so command data and diagnostics travel over a deterministic fiber-optic ring for synchronized control. As a member of the DIAX04 controller family, the device mates with common supply modules and I/O cards through a standardized backplane connector. Thermal loads are handled by a built-in air blower that draws air through the heat sink and ejects it at the top of the housing, eliminating the need for external ducting. The power stage is rated for 200 A of continuous motor phase current, allowing it to drive high-inertia axes under sustained load. Current monitoring circuits respond quickly if that limit is exceeded, helping protect the power section during demanding motion cycles.

The product is Version 2, indicating the second hardware revision in this model line. It is part of Line 04, placing it within the mid-range performance group of the DIAX04 platform. The unit is classified as an HDS Drive Controller, so it follows the control structure used for SERCOS-based HDS axes. These identifiers distinguish the controller within the series and separate it from units with different design lines or revisions.
