Product Description:

The HDS03.2-W100N-HS87-01-FW drive controller is produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within a DIAX04 modular drive stack, the unit acts as the power and control stage for servo axes by converting DC-bus energy into commanded motor current and supervising feedback signals. It installs in a control cabinet rack and links with adjacent modules so coordinated motion can be managed in packaging, printing, and general handling equipment. In a cabinet-based system, it processes motion commands from the master control and supports controlled acceleration, speed holding, and stopping across multiple axes. It is intended for applications that need repeatable servo response rather than simple open-loop motor switching.

Communication with the higher-level control system uses the SERCOS fiber-optic ring, enabling deterministic cyclic exchange of command data and diagnostics. This time-synchronized communication helps the drive system maintain accurate position and speed control during coordinated machine movement. As a member of the DIAX04 family, the controller uses the mounting format shared by related modules in the same platform. The shared platform layout also helps keep electrical and mechanical integration consistent across neighboring modules in the rack. A built-in air blower routes cooling air across the heat sinks, so no separate fan tray is required for the unit itself. The power stage can deliver 100 A of continuous current for connected servo applications. The enclosure has an IP 10 rating under DIN 40 050, which provides basic protection against accidental contact with internal parts while the control cabinet provides the additional enclosure protection.

Operation is permitted up to 1000 m above sea level without derating. The internal wiring uses C insulation class under DIN VDE 0110. Normal service temperatures range from +5 to +45 °C, and output is reduced at +55 °C. The controller withstands storage and transport temperatures from -30 to +85 °C when it is powered down. The unit is part of Line 03 and Version 2, and these identifiers indicate the revision used for this drive type. Ambient conditions outside the stated operating range require reduced loading or additional cabinet cooling.
