Product Description:

The HDS05.2-W300N-HS59-01-FW is a modular drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. It converts motion commands from a higher-level CNC or PLC into regulated current, velocity, and position values for connected servo axes. By closing these loops in real time, the unit supports accurate axis motion in machining centers, packaging lines, and other automated equipment. That closed-loop behavior helps the connected motors follow commanded speed and position changes during synchronized machine operation. This makes it suitable for coordinated motion tasks that require repeatable response under changing loads.

Command and diagnostic traffic passes over the SERCOS fiber-optic interface, providing deterministic cycle times and electrical isolation from noisy three-phase mains. Within the controller rack, the module occupies the master axis slot of the DIAX04 platform, so its connector profile and address range match the rest of that family. Thermal management is handled by an internal air blower that circulates cabinet air through molded channels in the heat sink, eliminating external ducting. The power stage is rated for a continuous output of 300 A, which allows direct connection to large servo motors without intermediate reactors and supports high torque demand on large axes. The designation line 05 identifies the mechanical frame size and bus bar geometry used with matching supply and brake modules.

The hardware is released as version 2, placing the unit in the second revision of this model. The unit is classified as an HDS Drive Controller, which means it serves as the regulation and power section for a servo axis rather than as a supply module. Common back-plane dimensions across the HDS Drive Controllers range keep the mounting outline consistent in compatible racks. The module format also supports organized power and signal routing inside multi-axis cabinets. It is intended for installations where several servo axes share one drive assembly.
