HDS03.1-W075N-HT05-01-FW Bosch Rexroth Indramat

Product Description:

The HDS03.1-W075N-HT05-01-FW is a modular axis module manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It operates inside a DIAX multi-axis rack, where it receives high-level motion commands and regulates current, speed, and position for associated servo or induction motors. By converting DC bus energy into controlled three-phase output, the unit forms a central element in automated machining centres, packaging lines, and material-handling robots.

Its continuous output capability is rated at 75 A, enabling the controller to drive medium-power axes without thermal derating. Command data are exchanged over the SERCOS fibre-optic interface, which provides deterministic timing and electrical isolation between the drive and the master. The unit belongs to the DIAX04 controller family, so parameter files and diagnostic codes match other modules in the same rack. Cooling is accomplished by a built-in internal air blower that forces air through the heatsink and out of the housing. Hardware coding is identified as Line 03, indicating the third design line with specific connector orientation and component revisions.

This module carries firmware slot 01 and hardware revision 1, aligning it with the earliest parameter set released for the platform. As an HDS Drive Controller, it shares enclosure dimensions, mounting rails, and bus connections with sibling units, simplifying cabinet layout. Integrators can combine it with power supplies, motor cables, and feedback options from the Bosch Rexroth Indramat catalogue without mechanical adapters. Within the HDS Drive Controllers range the 75 A rating positions the device between 50 A and 100 A models, allowing balanced sizing of axes that demand moderate peak torque.
