Product Description:

The HDS04.2-W200N-HT19-01-FW is a digital drive controller built by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. It occupies a slot in multi-axis DIAX modular racks and forms the power stage that converts DC bus energy into controlled three-phase output for servo and spindle motors. In automated assembly lines, material-handling gantries, and printing presses, the unit regulates motor speed, torque, and position so the motion sequence matches the programmed profile. This allows the controller to serve as the electrical link between the shared rack supply and the connected motor while the higher-level control system issues motion commands.

The controller exchanges cyclic setpoints and feedback through the SERCOS optical bus, which minimizes wiring and provides deterministic timing between the drive and the PLC. The optical link also supports synchronized command execution across multiple axes in the same system. A continuous output of 200 A allows the module to energize large-torque motors without current derating during long production runs. Heat is expelled by a built-in air blower, which draws cabinet air across the heat sink so external ducting is unnecessary. As part of the DIAX04 platform, the unit uses the same mechanical format and connector arrangement as related rack modules. The controller also monitors rated current and trips if RMS demand exceeds the specified limit, protecting semiconductors from thermal overload.

The product is part of Line 04 and uses hardware Version 2. These identifiers indicate the design line and hardware revision used for this controller. It can be paired with HG or HM power supplies to build a single-axis station or to expand an existing motion network. That arrangement supports both isolated axis groups and larger rack-based systems that use centralized power distribution.
