Product Description:

The HDS03.2-W100N-HT73-01-FW is a drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Inside a multi-axis cabinet it supplies regulated DC power and closed-loop control to servo amplifiers, forming the motion backbone of DIAX04 automation racks. By converting line energy and relaying SERCOS telegrams, it synchronizes motor torque, speed, and position with the machine program.

The controller exchanges motion commands over the SERCOS fiber-optic bus, allowing deterministic communication between PLCs and drives. It belongs to the DIAX04 controller family, so it shares back-plane, firmware, and diagnostic conventions across that platform. Thermal loads are managed by a internal air blower that draws cabinet air across IGBT heat sinks, eliminating external ducting. A nominal output of 100 A lets the unit handle high-inertia axes without derating, while dynamic current limiting protects components during transients. Hardware release Version 2 adds enhanced error logging and revised gating for reduced switching losses.

Within the product hierarchy it is assigned to Line 03, a designation that dictates its mechanical outline and connector set for quick swapping in DIAX04 racks. As part of the HDS Drive Controllers series it incorporates standardized parameter structure, easing firmware updates across identical axes. 

Wake Industrial can arrange same-day shipping for maintenance crews, supplies a 1-year warranty with every purchase, and keeps quotations valid for 30 days to simplify budgeting.
