HDS03.2-W075N-HS72-02-FW
The HDS03.2-W075N-HS72-02-FW is a digital drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in a multi-axis rack, it links the central motion processor to the individual motor power sections and converts setpoint data into controlled phase current for servo and spindle axes. This control process supports accurate velocity, torque, and position regulation in packaging systems, material transfer equipment, machining machinery, and other automated production lines. In this role, it helps synchronized axes follow commanded motion profiles during acceleration, steady operation, and deceleration.
The command communication interface is SERCOS, so fiber-optic telegrams carry real-time parameters and diagnostic feedback between the controller and the higher-level PLC. Thermal management uses a built-in air blower that moves cabinet air across the heat-sink channels to keep semiconductor temperatures within the operating range. The power section is designed for a continuous output of 75 A, which supports high-torque acceleration profiles for large synchronous or induction motors. This current level also allows sustained load handling without immediate thermal derating. The unit is part of Line 03, which keeps it compatible with the third design line of DIAX modules while preserving the established mechanical footprint.
Within the DIAX04 platform, the controller uses the parameter structure and plug-in option card support assigned to this product group. It is released as Version 2, reflecting incremental updates in gate-drive logic and protective monitoring compared with the initial release. The unit is an HDS Drive Controller, which means axis control and power conversion are integrated in one housing rather than split between separate servo amplifiers. This arrangement keeps the rack layout straightforward and maintains the module format used across the platform.
