Product Description:

The HDS03.2-W075N-HT25-01-FW is a digital drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. In an automated cell, the module converts bus commands into controlled current and voltage for synchronous or induction servomotors. It acts as the link between higher-level motion control and the mechanical load, allowing coordinated axis movement under PLC supervision. This supports accurate positioning, stable speed regulation, and repeatable torque control in packaging, printing, and material-handling equipment. The controller is used where servo axes must start, stop, and track commanded motion without large deviations under changing load conditions.

Communication is handled through SERCOS on a deterministic 2 kHz fiber-optic cycle, so setpoints and feedback are exchanged with other axes on the network at consistent intervals. The controller can deliver a continuous output of 75 A, which suits medium-power motors without an external amplifier stage. As part of the DIAX04 platform, the unit uses carrier dimensions and backplane connectors shared with related modules. Thermal loading is managed by a built-in air blower that pulls air through the heat sink to keep internal components within their operating range. This cooling method supports cabinet installation without requiring air exchange through the enclosure.

The product is part of Line 03, which marks its design line within the series. The unit is released as Version 2, providing a fixed revision reference for setup records and parameter documentation. Its cabinet-mounted format is intended for multi-axis systems where several drives share a common motion network and respond to coordinated commands. This arrangement suits machines that group power modules and control hardware in a single enclosure while keeping axis response closely synchronized. Because the controller regulates motor current directly, it can support repeatable motion profiles during continuous industrial operation.
