Product Description:

The HDS03.2-W075N-HT29-02-FW axis module is produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Designed for insertion in a multiaxis automation rack, the unit bridges high-level motion commands from a PLC with the regulated current required by servo motors. By translating position and velocity setpoints into accurate power output, it supports coordinated movement, electronic gearing, and closed-loop speed regulation across packaging, printing, and material-handling machinery. Its compact form factor allows rack mounting beside additional drive modules that share a common DC bus, which helps conserve cabinet space and keep system wiring centralized.

I/O communication is handled through the SERCOS optical ring, which carries real-time setpoint data and drive status at deterministic update rates. That communication path supports synchronized axis updates when several modules must respond together during coordinated motion. The power stage delivers a continuous output of 75 A, so motors that draw up to this current can be accelerated and decelerated without derating. Thermal management relies on a built-in air blower that forces air across the heat sink fins and maintains stable internal temperature during sustained operation. The controller belongs to the DIAX04 family, so its parameter structure, diagnostic codes, and mechanical dimensions match other modules in the same rack.

The device is an HDS Drive Controller and is part of Line 03 in the series. It carries the order code suffix 02-FW and is built as Version 2. These identifiers distinguish the unit within the product line without changing its basic role as a single-axis drive module. In operation, it serves as the regulated power section for one axis while the higher-level controller manages the motion sequence.
