Product Description:
The HDS03.1-W100N-HA32-01-FW belongs to the HDS Drive Controllers series produced by Bosch Rexroth Indramat. This unit functions as a digital drive controller that supplies regulated current to Indramat servo drives within the DIAX modular automation platform. In industrial automation, the controller governs motor torque and speed through closed-loop current regulation so positioning and process axes can follow programmed profiles.
The command interface is electrical and accepts an ANALOG reference signal, allowing drives in legacy or mixed-control installations to receive continuous voltage or current commands. Within the DIAX platform it is identified as part of the DIAX04 controller family, which standardizes dimensions and bus links for multi-axis racks. Thermal management is handled by a built-in internal air blower; this fan draws cabinet air through the heatsink fins so the module can dissipate switching losses without external ducting. The power section is sized for a continuous output of 100 A, enabling it to drive high-torque motors on presses, gantries, or injection units. Hardware coding places it in line 03, indicating the performance class and connector arrangement that must be matched when replacing or extending an axis.
Firmware and hardware are locked to version 1, guaranteeing parameter compatibility across installations produced in the same build cycle. The product identifier also confirms it is an HDS Drive Controller, and the manufacturer lists no other versions for this specific ordering code, simplifying spare-part logistics. Engineers integrating the unit should observe the stipulated rated current limit during configuration so that drive sizing, cable cross-section, and protective devices remain within allowable thermal margins.
