HDS03.2-W100N-HS65-01-FW
The HDS03.2-W100N-HS65-01-FW is a drive controller module produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It occupies a single slot in a DIAX04 automation rack, where it delivers regulated DC bus power and motion commands to connected servo axes. In that role, it links higher-level control logic with the motor windings used in coordinated axis control. This arrangement allows multiple axes in one cabinet to respond in a synchronized and predictable manner during machine operation.
The controller exchanges deterministic real-time data through the SERCOS optical interface, which synchronizes position feedback and drive status with a PLC over a fiber ring and keeps cyclic command transfer resistant to electrical noise. Its power stage supports a continuous output of 100 A, enabling the unit to supply high-torque motors without thermal derating under nominal cabinet conditions. A built-in air blower draws cooling air directly across the heat sinks so the module can be mounted in densely packed enclosures without external ductwork. The unit follows the DIAX04 family architecture, which keeps diagnostics and parameter handling consistent across multi-axis installations and supports uniform operating behavior within the rack. Hardware revision 2 adds improved gate-drive circuitry, providing greater switching margin when the full rated current is delivered to the motor phases.
The unit is assigned to line 03, so its mechanical footprint, connector orientation, and busbar spacing match other current ratings in the same hardware class. It is used alongside HMS supply modules where coordinated fault handling is required within a shared drive system. This layout supports racks that distribute power over a common DC link and group several axes in one enclosure. The module format also helps maintain orderly cable routing and consistent placement inside compact control cabinets.
