HDS03.1-W075N-HA05-01-FW
The HDS03.1-W075N-HA05-01-FW is a modular drive controller produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. The unit distributes regulated DC link energy from a central supply module to individual servo axes, coordinating motion sequences in packaging lines, machine tools, and material handling equipment. In a multi-axis system, it works as the link between the central power section and the controlled motor axis, supporting precise torque and motion control. It performs axis control and current regulation while relying on a separate HVE or HVR supply for DC bus energy.
Its nominal output stage handles 75 A of continuous motor current, allowing medium-power axes to be driven without external amplifiers. Command values enter the controller over an analog interface, so velocity or torque setpoints can be supplied as ±10 V signals from a PLC or motion card. This input method suits systems that use conventional voltage references rather than network-based command transmission. Thermal management is provided by a built-in air blower, which directs cabinet air across heat-generating components without requiring chilled liquid or external ducts. The controller belongs to the DIAX04 family and is part of Line 03.
The unit is Version 1. It is classified as an HDS Drive Controller, and it shares mechanical dimensions, front-panel diagnostics, and SERCOS backplane connectors with companion modules in the series. Protective functions such as overcurrent shutdown, temperature monitoring, and short-circuit detection are handled internally and can be enabled through serial parameter settings without auxiliary boards. The shared dimensions and connector layout keep installation geometry consistent in multi-axis cabinets. That modular layout allows related drive modules to sit side by side on the same platform.
