HDS03.2-W075N-HT10-01-FW
The HDS03.2-W075N-HT10-01-FW drive controller is built by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. As an HDS drive controller, it supplies regulated three-phase power for DIAX04 servo axes, enabling coordinated motion in automated lines. The unit receives setpoints from a SERCOS master and modulates output current so that servo motors track commanded profiles. In an industrial cell, this controller forms the electrical interface between the central PLC and the mechanical load, maintaining velocity, position, and torque accuracy during production.
Rated output capability is 75 A, meaning the power section can continuously deliver this magnitude of phase current to connected motors without thermal derating. This current rating supports axes that require sustained torque over long operating periods. Command data enter over the SERCOS fiber-optic ring, a real-time fieldbus that transfers position and status information in short cycles and eliminates separate analog references. Internal cooling is handled by a built-in air blower; the fan draws cabinet air across heat sinks so external ducting is not required. The unit is part of Line 03, which identifies the mechanical layout and connector arrangement, and the controller is Version 2.
The controller is part of DIAX04, so motion modules, power supplies, and communications accessories in that platform share the same bus and mounting standards. Within the HDS Drive Controllers series, the unit follows the modular layout used for multi-axis assemblies, so it can be installed alongside related drive components in the same rack. In the Bosch Rexroth Indramat product range, the device is classified as an HDS Drive Controller rather than a supply module or accessory. That classification matches its role as the current-regulating stage between the command source and the motor.
