HDS03.1-W075N-HS28-01-FW

Product Description:

The HDS03.1-W075N-HS28-01-FW is a modular drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in a DIAX04 cabinet, it occupies one rack slot and converts DC bus energy into phase-controlled currents for synchronous or induction servo motors. In industrial automation it governs a single axis, generating regulated torque, speed, and position while exchanging motion data with higher-level control hardware.

The controller transmits set-points and diagnostics over the SERCOS optical ring, ensuring deterministic timing for coordinated moves. It is part of the DIAX04 family, so its pin-out and parameter structure match companion supply and I/O modules. A built-in internal air blower moves cooling air across the heat sink, allowing continuous duty without external ducting. Continuous output is limited to 75 A, defining the highest RMS phase current available to connected motors. Mechanical assignment code 03 specifies the module height, guide-rail spacing, and mounting screws that fit third-generation HDS racks.

As an HDS Drive Controller, the unit loads firmware identified by the -FW suffix and executes closed-loop current, velocity, and position algorithms. Hardware revision 1 fixes the component layout and gate-array logic, simplifying spare-part stocking for maintenance teams. Developed by Bosch Rexroth Indramat, it follows uniform diagnostic codes that shorten troubleshooting across mixed motion racks. There are no other versions of this order designation, removing variant management during commissioning and enabling straightforward parameter replication when multiple axes use identical controllers.
