HDS03.1-W100N-HA30-01-FW
The HDS03.1-W100N-HA30-01-FW is a modular drive controller produced by Bosch Rexroth Indramat in the HDS Drive Controllers series. Installed in multi-axis systems, the unit regulates servo and induction motors on production lines, packaging stations, and material-handling axes. It converts velocity or torque commands into controlled motor current, helping the connected motor follow the required motion profile. Because the output current is regulated electronically, the controller can support repeatable speed control and coordinated axis response during changing load conditions.
The controller exchanges command information through an analog command interface, so voltage or current references from a PLC can set the demanded speed or torque. Its continuous output capability reaches 100 A, which is the maximum motor phase current the drive can supply without thermal derating under rated conditions. Heat generated at that load is removed by a built-in air blower, so cooling air is provided inside the unit rather than by a separate external fan. This arrangement helps keep internal components within their normal operating temperature range during sustained operation. It also supports compact installation in rack-based drive assemblies where multiple axes are grouped together.
The unit is part of the DIAX04 platform, where the associated backplane distributes DC-bus power and shared logic signals among multiple axes. It is assigned to Line 03 in the series and is identified as Version 1. The controller is used as a standardized axis module in rack-mounted drive assemblies, allowing it to operate alongside matching modules in the same system. Its form and function are intended for coordinated use within multi-axis layouts that rely on shared bus structure and centralized control signals.
