HDS03.2-W100N-HA27-01-FW
The HDS03.2-W100N-HA27-01-FW is a drive controller produced by Bosch Rexroth Indramat and positioned within the HDS Drive Controllers series. It governs the current and velocity loops of connected servo axes inside modular drive racks, translating external motion commands into regulated motor current so automated machinery can maintain repeatable positioning, cutting, or assembly cycles. This arrangement supports stable speed response during dynamic moves and helps the connected motor follow command changes under varying load. The module is intended for axis control tasks where local regulation is handled directly inside the drive.
The controller exchanges setpoint and feedback data through an analog command interface, meaning it accepts ±10 V or 0–20 mA references instead of a digital fieldbus. It is part of the DIAX04 family, allowing installation beside matching power supplies and communication cards in the same rack. Thermal management is handled by a built-in air blower that forces air over the heat sink to maintain semiconductor temperatures at rated load. The power section can deliver a continuous output of 100 A for medium- to high-torque servomotors. Current regulation, velocity control, and protective diagnostics are executed locally on the module.
The designation 03 identifies the third design line and matches the mechanical footprint and busbar spacing used by related modules in the platform. The unit is Version 2, which indicates the revision level of this controller. When used with compatible supply modules and interface cards, the controller shares the cabinet air path and the common DC link, allowing compact multi-axis arrangements while each axis retains its own tuning parameters. This layout supports dense rack installation without adding a separate controller for every axis.
