HDS03.2-W075N-H3
The HDS03.2-W075N-H3 is a modular control unit manufactured by Bosch Rexroth Indramat within the HDS Drive Controllers series. It installs in a DIAX04 rack to supervise a single motor axis, translating drive setpoints from the system PLC into regulated armature and field currents. In industrial automation, this arrangement lets multiple axes share a common power supply while preserving coordinated motion. It also supports synchronized velocity, torque, and position control across packaging lines, transfer systems, and other automated machinery. This control profile suits single-axis sections of larger multi-axis systems where stable current regulation is required during speed changes and load shifts.
Belonging to the DIAX04 controller family, the module sits on Line 03 and is identified as Version 2. The power stage is rated for a continuous output of 75 A, providing headroom for medium-to-high inertia servo or spindle loads. Thermal management relies on a built-in air blower that draws cooling air through the card cage rather than requiring external ducting. Because the blower is integrated, the module can be installed in dense cabinets without separate fans. Diagnostic monitoring tracks blower speed, current level, and heat sink temperature, so an airflow restriction triggers a controlled shutdown instead of an abrupt fault.
Within the rack, the controller connects to the common axis bus, sharing DC link energy with adjacent modules and supporting regenerative braking. The hardware is classified as an HDS Drive Controller. Its slim, rack-mount format allows tight stacking while still providing front access to status LEDs and plug-in memory cards. That layout keeps the module accessible from the front of the rack and avoids extra side clearance for routine handling. The front-access arrangement also helps preserve cabinet space when several drive modules are installed side by side.
