The HDS03.1-W100N-HA12-01-FW is a drive controller manufactured by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. It is installed in multi-axis cabinets to act as the controlled power interface between the mains supply and servo motors, supplying precisely modulated current so that each axis can follow position and speed commands in industrial automation lines such as packaging, metal-cutting, or electronic assembly.
The controller exchanges setpoints and feedback through a ANALOG command communication interface, so every velocity or torque reference reaches the internal regulator as a continuously variable signal. A continuous output capability of 100 A defines the maximum current it can deliver to stator windings without thermal derating, establishing the permissible motor size on the axis it feeds. Thermal management is handled by a Built-in Internal Air Blower; this dedicated fan directs airflow across heat-sinks and keeps semiconductor junctions within their safe operating temperature. The unit belongs to the DIAX04 controller family, which standardizes back-plane bus connections so multiple drives can share a common supply and diagnostic environment. Within that family it resides in hardware Line 03, indicating mechanical dimensions and connector layout that match the third-generation back-panel spacing.
Firmware and hardware identifiers place this model in Version 1, ensuring that parameter files and motion libraries compiled for early releases load without modification. Its designation as a HDS Drive Controller clarifies that it combines power stage, control electronics, and protective monitoring in one housing, rather than requiring separate amplifier modules. Bosch Rexroth Indramat’s commitment to interchangeability means identical mounting points and field-bus addresses across the family, and the absence of alternate variants for this catalog code simplifies spare-part stocking. Within the Bosch Rexroth Indramat motion platform, the HDS Drive Controllers series lets system builders scale from single-axis stations to synchronized multi-axis cells while maintaining a common programming and diagnostics toolchain.
