Product Description:

The HDS03.2-W075N-HS74-02-FW is a modular axis inverter manufactured by Bosch Rexroth Indramat and supplied in the HDS Drive Controllers series. It is installed on a shared power bus to modulate three-phase output for servo or induction motors while exchanging command data with higher-level motion control. In this role, it converts energy from the common DC bus into controlled motor current for individual axes. Typical use includes packaging, printing, and material-handling stations where accurate velocity regulation and coordinated positioning are required. Its plug-in architecture supports fast cabinet assembly and reduces extra wiring inside the enclosure.

The module communicates through SERCOS, a fiber-optic serial interface that supports synchronized setpoint and feedback cycles across machine axes. This communication method also helps maintain reliable data transfer in electrically noisy drive cabinets. Continuous motor current is limited to 75 A, so the connected load must remain within the drive's current and thermal capacity. Heat from IGBT switching is removed by an internal air blower, which helps keep the heat sink within its operating range without external ducting. As part of the DIAX04 platform, the unit uses the same backplane and communication structure as other modules in the system.

The product is part of Line 03 and is built as Version 2. It is identified by the manufacturer as an HDS drive controller, so it occupies the servo inverter slot rather than the power supply position in an axis rack. The original Bosch Rexroth Indramat designation is used to match the correct line and version for the unit. In a shared-bus system, that arrangement separates the axis control stage from the central supply module. These identifiers indicate the product generation used for this controller type.
