Product Description:

The HDS03.1-W100N-HA25-01-FW is a modular drive controller produced by Bosch Rexroth Indramat in its HDS Drive Controllers series. Positioned within multi-axis DIAX04 systems, this unit provides closed-loop regulation for AC servo and spindle drives used on packaging lines, material-handling gantries, and similar automated machinery. By converting reference signals into controlled motor power, it coordinates speed, torque, and positioning functions inside an industrial motion cabinet.

The controller exchanges velocity or torque set-points through a ANALOG command communication interface, so it integrates with legacy PLC hardware that relies on voltage or current references instead of fieldbus telegrams. Thermal management is handled by a Built-in Internal Air Blower; this fan draws cooling air through the heatsink to keep power semiconductors within safe junction temperatures without external ducting. For axis groupings that impose high dynamic loads, the drive can supply a continuous output of 100 A, a rating that defines the maximum RMS current the connected motor windings may receive under steady-state operation. It belongs to the DIAX04 controller family, meaning its firmware and parameter structure match other DIAX04 components for unified commissioning. The catalog lists None as the alternative hardware variants, so all application adaptations must be accomplished through firmware or parameter changes rather than board swaps.

Within the Bosch Rexroth Indramat product range, the unit falls under the HDS Drive Controllers series; this classification guarantees compatibility with HVE supply modules and HMS inverters that share the same DC bus. The line code 03 designates the third mechanical platform, giving it connector locations and dimensions standardized across that generation. Firmware revision control is tied to version 1, so motion libraries and diagnostics must target this baseline when creating backup files or downloading updates.
