HDS03.1-W075N-HA10-01-FW
The HDS03.1-W075N-HA10-01-FW is a drive controller module manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Installed in a DIAX-configured cabinet, the unit interfaces with power supplies and servo motors to regulate axis motion in automated machining centers, packaging lines, and material-handling cells. It converts command references into controlled motor currents while monitoring internal states so that the connected axis follows programmed velocity or torque profiles with high repeatability. The controller is used where a separate supply module provides the DC bus and the drive stage converts that energy into regulated current for the motor windings.
The command communication interface is analog, meaning the axis card interprets ±10 V speed or torque references generated by a motion controller and scales them into internal setpoints. A continuous output capability of 75 A allows the power section to energize medium-frame synchronous or induction motors without external boosters. Thermal energy produced by the switching devices is removed by a built-in air blower, which provides a self-contained cooling path and keeps heat sink temperature within permissible limits. This arrangement allows the drive to respond to continuously varying reference signals from higher-level motion electronics without requiring a digital command network. The module belongs to the DIAX04 controller family, and it carries the line code 03, which groups compatible mechanical dimensions and connector layouts for rack installation.
Functionally, the product is classified as an HDS Drive Controller, indicating that it receives a mains-isolated DC bus from a supply unit and furnishes three-phase output to a single motor. The unit is released as version 1, which identifies the product generation used for this controller. Its operating role fits single-axis motor control where an external controller provides the command reference and the drive regulates motor current directly. Because the unit serves one motor at a time, it suits cabinet layouts that separate supply, control, and power functions into coordinated modules.
