Product Description:

The HDS03.1-W075N-HT13-01-FW belongs to the HDS Drive Controllers series from Bosch Rexroth Indramat. As a modular axis controller it forms part of a multi-axis DIAX04 system and is installed in cabinet-mounted automation racks to regulate torque, speed, or position of synchronous and induction motors. Used with SERCOS or analogue interface units, it supplies regulated power to the attached drive while monitoring operational limits, making it a central element in machining centres, printing lines, and material-handling cells.

This model exchanges set-point and diagnostic data through the SERCOS fibre-optic ring, which permits deterministic communication between the controller and higher-level motion hardware. During operation it can deliver a continuous output of 75 A; that rated current defines the maximum RMS line current the power section must handle without derating. Cooling is managed by a built-in internal air blower, so ambient cabinet air is drawn across the heat sink and expelled without the need for external ducting. The drive is assigned to the DIAX04 controller family, allowing it to share power supplies, bus modules, and firmware tools common to that platform. Within the HDS naming scheme it is marked as 03, signifying the hardware line that determines geometry, connector layout, and permissible expansion cards.

The firmware trunk is identified as revision 1, indicating baseline parameter structures and diagnostic codes for this release cycle.The unit inherits protective functions, memory mapping, and configuration logic defined for the Bosch Rexroth Indramat motion platform while remaining fully interchangeable with other controllers inside the HDS Drive Controllers series. Together these attributes streamline cabinet layout, reduce integration time, and keep service inventories consistent across multiple machine generations.
