Product Description:

The HDS03.2-W075N-HA01-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed inside multi-axis racks, it closes current and velocity loops for servo motors used in packaging, machining, and material-handling cells. The module combines power semiconductors, signal conditioning, and forced-air cooling so that one slot can provide precise motor regulation without external amplifiers. Within an automated line, it converts command references from the central motion processor into controlled three-phase output for connected axes. Its control stage supports smooth acceleration, steady-speed operation, and repeatable response during frequent start-stop cycles. It is typically used where several servo axes share one supply structure and centralized control hardware.

The unit exchanges motion commands through an analog interface, so velocity or torque references arrive as ±10 V signals that are processed by its digital control card. It belongs to the DIAX04 controller family, so the module works with a shared DC bus and common feedback channels used across that platform. Continuous demand is supported by a rated output of 75 A, which is the maximum root-mean-square motor current available without derating. Thermal energy is removed by a built-in air blower, allowing the drive to dissipate switching losses while the control electronics remain within the allowable temperature range. This combination supports compact rack integration for coordinated axes that must follow changing speed or torque commands.

The product is part of Line 03 and is Version 2, which distinguishes it from earlier releases in the same family. As an HDS drive controller, it uses the same mechanical footprint and backplane connectors as neighboring modules in the rack. Because the blower is integrated, the unit does not require a separate external cooling attachment, and ambient air is drawn through the heat sink during cyclic acceleration duty. The rack-based format keeps power and signal connections organized inside centralized motion systems. The layout also helps keep wiring paths short inside dense machine cabinets. It is suited for applications that need stable current control, consistent speed regulation, and compact cabinet installation.
