HDS03.1-W075N-HA20-01-FW Bosch Rexroth Indramat

Product Description:

The HDS03.1-W075N-HA20-01-FW is a motion-control module produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in an automation rack, it receives set-point data, supervises drive status, and relays precise current commands to connected power amplifiers. By closing the velocity and torque loops, the unit enables coordinated positioning and speed regulation in machine tools, packaging lines, and robotic cells.

Electrical loading capability is set by a continuous output of 75 A, enabling high-torque servo axes without current derating. Command values enter through a ANALOG channel, so ±10 V or 0–10 V references can be accepted directly from higher-level controllers. Excess heat is expelled by a built-in internal air blower that draws cabinet air through the heat sink to avoid thermal shutdown. Integration with the DIAX04 controller family keeps parameter lists and back-plane communication consistent across mixed racks. Hardware coding places this model in line 03, and its circuit boards correspond to design revision 1, giving service technicians a clear reference when selecting replacement parts.

According to the type plate, alternative build codes are listed as None, so functional interchange is limited to exact matches. The classification HDS Drive Controller designates firmware-based axis logic that pairs with external power sections instead of embedding power electronics on the card. For plants that standardize on Bosch Rexroth Indramat hardware, this controller fits the same wiring topology and diagnostic routines already in place, ensuring uniform commissioning procedures across multi-axis installations.
