Product Description:

The HDS04.2-W200N-HT02-01-FW is a drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. It serves as the regulated power stage for DIAX04 servo modules, translating motion commands from a PLC into precise current and voltage for each motor axis. In industrial automation cabinets this unit coordinates speed, torque, and position loops so multi-axis machines maintain repeatable accuracy and cycle times.

Communication with the motion supervisor occurs over the high-speed SERCOS fiber-optic bus, reducing electromagnetic interference and simplifying synchronous updates. Membership in the DIAX04 family guarantees mechanical and firmware compatibility with other modules from the same rack. Thermal management is handled by a Built-in internal air blower, eliminating the need for external cabinet fans and keeping semiconductor junctions below critical limits. The power stage sustains a continuous output of 200 A, enabling it to drive large torque motors without derating. Within the product hierarchy it is assigned Line 04, indicating its electrical frame size and connector layout.

Hardware Version 2 introduces diagnostic refinements that shorten commissioning time and improve fault isolation compared with earlier releases. The controller retains the modular back-plane format of the HDS Drive Controllers series, allowing quick insertion beside supply and auxiliary cards. Engineering from Bosch Rexroth Indramat ensures firmware matches established DIAX04 parameter structures, so legacy motion programs remain usable. Categorized explicitly as an HDS Drive Controller, the unit is therefore selected when synchronized multi-axis coordination and field-replaceable service are priorities.
