Product Description:

The HDS03.1-W100N-HS02-02-FW is a multi-axis drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It converts high-level motion instructions into phase-accurate switching of the attached power section, enabling servo and spindle motors in automated machinery to follow precise setpoints. The module occupies one slot in a modular rack and pairs with compatible power interfaces to build scalable drive assemblies in packaging, printing, and robotic installations.

The command channel is the SERCOS fibre-optic interface, which carries position, velocity, and diagnostic telegrams in real time while ensuring electrical isolation from noisy power cabinets. Within the controller hierarchy it belongs to the DIAX04 family, so parameter structures and firmware options match the modular motion platform used across many Rexroth axes. Thermal management relies on a Built-in Internal Air Blower, drawing cabinet air through the heatsink to keep semiconductor temperatures inside allowable limits without external ducting. The hardware is identified as Line 03, indicating the third design generation that introduced higher bus speeds and updated gate arrays. For continuous operation the current regulator is rated at 100 A, permitting it to drive large torque motors or parallel axes without derating under nominal cooling.

Firmware designation Version 1 defines the software kernel that interprets motion telegrams and supervises protective functions such as overcurrent shutdown and temperature monitoring. As an HDS Drive Controller it integrates seamlessly with auxiliary supply modules and motor feedback cards taken from the same platform, allowing machine builders to assemble axis groups with consistent diagnostics. The manufacturing signature Bosch Rexroth Indramat guarantees spare-part interchangeability because mechanical dimensions, connector pin-outs, and parameter maps remain fixed across the range. Membership in the HDS Drive Controllers series also means that enclosure profiles, mounting rails, and addressing conventions are common, simplifying cabinet layout when multiple units share a backplane.
