Product Description:

Bosch Rexroth Indramat’s HDS03.2-W100N-HA44-01-FW installs in a drive cabinet to supervise one motion axis. The product is a closed-loop power stage that receives command values from higher-level controls and issues regulated output to synchronous or induction motors used in automated assembly cells, gantries, and machining centers. Because the unit regulates output in closed loop, it can respond to changing load conditions during indexing, feed motion, and coordinated positioning. It handles current regulation and fault supervision inside the module while position loops are managed by the higher-level CNC or PLC.

The module accepts setpoint data over an analog interface, allowing velocity or torque references to be delivered as ±10 V signals from a PLC or motion card. This input method suits systems that use conventional voltage commands instead of a digital motion network. Thermal management relies on a built-in internal air blower; this fan draws cabinet air across the heat sink so continuous operation is possible without external ducts. The drive is rated for 100 A of output current, enabling it to pair with high-torque servo motors while maintaining margin for transient peaks during rapid acceleration. Integration into the DIAX04 controller family lets multiple HDS units share a common DC bus and communication backplane. The electronics are identified as Version 2.

Produced by Bosch Rexroth Indramat, the unit belongs to the HDS Drive Controllers series and is part of Line 03. It is classified as an HDS drive controller and is intended to work with matching supply modules in the same platform. That arrangement keeps cabinet integration consistent across related modules and supports coordinated placement with matching system components. The mechanical layout also stays aligned with the surrounding hardware used in the same rack.
