HDS03.1-W075N-HA07-01-FW
The HDS03.1-W075N-HA07-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series used in modular multi-axis systems. As an axis controller, the unit converts setpoint signals into regulated current for a connected servo axis, enabling coordinated motion in machine tools and handling stations. In a modular drive rack, it serves as the control and power stage for one motion axis and responds quickly to changing load demands during acceleration, steady speed, and braking. The housing is intended for control-cabinet installation, where it interfaces with upstream PLC hardware and adjacent system modules.
Its command interface is analog, so velocity or torque commands arrive as ±10 V signals instead of fieldbus data. The output stage is rated for 75 A of continuous motor current, which is the maximum RMS load it can supply to one axis without derating. Heat from the power section is removed by a built-in air blower, and the fan circulates cabinet air across the heat sink without requiring external ducting. This arrangement supports applications that use conventional analog command signals while still requiring fast current regulation inside the drive. The unit is part of the DIAX04 platform, so its dimensions and backplane connections match other modules in that generation.
The unit is part of Line 03 in the product range, so it shares the power bus arrangement used by other third-line versions. Its version is 1, indicating the first release of this build. Bosch Rexroth classifies the device as an HDS Drive Controller, which distinguishes it from supply modules and interface cards in the same rack. When it is installed beside supply units and master cards, the controller operates within a common DC bus architecture that allows regenerated energy to pass between axes. That shared bus layout helps balance energy flow during deceleration and reduces the need for each axis to handle returned power on its own.
