HDS03.1-W100N-HS27-01-FW
The HDS03.1-W100N-HS27-01-FW is a drive controller module from Bosch Rexroth Indramat in the HDS Drive Controllers series. Installed in multi-axis systems, the module works with separate power sections to manage speed, torque, and position loops in industrial automation equipment such as handling systems and machining centers. It interprets fieldbus commands and issues precise gating instructions to the connected drive hardware. This arrangement separates the control function from the high-power section, which is useful in cabinets that group several axes on a common platform. By keeping loop regulation in the controller module, the system can maintain coordinated motion across multiple connected axes.
The module exchanges real-time motion data over the SERCOS fiber-optic ring, so parameter words and drive status stay synchronized with the controller cycle without discrete wiring. Continuous output current of up to 100 A allows it to control high-torque servo axes without current derating during normal operation. Thermal management is handled by a built-in air blower that draws cooling air across the heat-sink fins, eliminating the need for external cabinet ventilators. The unit is part of the DIAX04 platform, so it uses the same standard parameter numbering and diagnostic telegrams used across that system. This keeps communication behavior consistent across compatible axes in the same drive platform.
In the Indramat nomenclature, line 03 identifies the third performance bracket, and version 1 indicates the initial release for this line. The product is classified as an HDS Drive Controller, and it fits coordinated multi-axis racks where separate power sections supply motor current. This layout keeps the control and power functions in dedicated modules, which suits larger drive assemblies that group several axes in one cabinet. It is intended to operate with separate power sections rather than an integrated supply stage. The line and version codes place the unit within the product range and distinguish it from control modules with different ratings or feature sets.
