HDS03.1-W100N-HS72-02-FW
The HDS03.1-W100N-HS72-02-FW drive module is produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Classified as a multi-axis power stage, it works with centralized motion control to supply regulated current to servo motors in industrial machinery. Within an automation cell, the controller bridges the higher-level PLC and the motor inverter, converting motion commands into gate-drive pulses while continuously monitoring fault conditions. In a shared-drive system, this role allows multiple axes to operate under one coordinated control platform without giving each motor a separate stand-alone controller.
Data exchange relies on the Command Communication Interface identified as SERCOS, which transmits cyclic setpoints and status words over a fiber-optic ring at deterministic intervals. Fiber-optic communication also helps the signal path resist electrical noise in cabinets that contain switching power electronics. Motion parameters are interpreted by the DIAX04 central control. Thermal regulation is handled by a built-in air blower that directs cabinet air across the heat sink without external ducting, allowing continuous delivery of 100 A of output current at the DC bus. This airflow keeps the power section within its operating temperature range during sustained motor demand.
The unit is part of Line 03 and is Version 1, identifiers tied to its connector arrangement and diagnostic behavior. It is an HDS Drive Controller that accepts supply units on the common DC link and provides four-quadrant operation with regenerative braking. With a common DC link, the module can exchange bus energy with companion axes during acceleration and deceleration. The -02-FW designation indicates a removable software module, which separates the control software from the main drive hardware. This layout keeps the parameter memory with the software module when it is moved between compatible units.
