HDS03.2-W100N-HA38-01-FW
The HDS03.2-W100N-HA38-01-FW is a drive controller manufactured by Bosch Rexroth Indramat in the HDS Drive Controllers series. It serves as the regulated power and control stage for servo axes in multi-axis automation systems, where accurate torque and velocity response are required. In DIAX-based installations, the unit works between the higher-level PLC and the connected motors so commanded motion can be translated into controlled electrical output. This arrangement supports coordinated axis behavior in production equipment that depends on stable drive performance during continuous operation.
The controller uses an ANALOG command interface, so operating references are received as differential voltage signals rather than through a digital fieldbus. Those analog inputs are processed by the internal regulator and converted into pulse-modulated output for the connected motor axis. The power section is rated for a continuous output of 100 A, which allows the unit to operate medium-to-large servo motors without current reduction under normal thermal conditions. Cooling is provided by a built-in air blower that moves cabinet air across the heat sink and helps keep switching components within an acceptable temperature range during sustained load cycles.
As part of the DIAX04 family, the controller uses the mechanical dimensions and backplane compatibility associated with that platform. The unit is Version 2, and this revision uses updated gate drivers to improve rise-time control and reduce electromagnetic emissions compared with the earlier release. It is assigned to Line 03, which places it in the third design line of the series. That line assignment means modules in the same line use the same general signal allocation and diagnostic LED placement, which keeps rack layout and module identification straightforward inside compatible assemblies.
