HDS03.2-W075N-HA26-01-FW
The HDS03.2-W075N-HA26-01-FW belongs to the HDS Drive Controllers series produced by Bosch Rexroth Indramat. As a modular drive controller, it is installed in multi-axis racks to regulate servo and spindle power modules in automated machining cells, packaging lines, and material-handling equipment. By interfacing with upstream motion processors, the unit sends current commands that shape motor torque and speed for coordinated axis control. In these systems, it serves as the control stage between higher-level motion commands and the power electronics that energize the motor.
This controller receives velocity or torque references through an analog command interface, so drive behavior is controlled by ±10 V signals rather than a digital network. The continuous output capability is rated at 75 A, which is the maximum RMS phase current the downstream power section can supply to connected motors during continuous operation. Cooling is handled by a built-in air blower that moves air across heat-generating components and helps keep internal temperatures within the normal operating range. Because the command input is analog, the controller can follow external reference sources used in legacy or dedicated control architectures. This arrangement supports stable performance when the controller is installed in enclosed drive assemblies.
The unit is part of the DIAX04 family and is assigned to Line 03, which indicates its design line within the series. It is released in hardware Version 2, identifying the revision used for this model. The product is classified as an HDS drive controller, which distinguishes it from converter and servo drive types in other Rexroth product groups. It mounts in a DIAX04 rack beside matching power sections and related modules used for closed-loop motor control. This rack-based format keeps control and power connections grouped within the same modular drive system.
