HDS03.2-W100N-HT27-02-FW
The HDS03.2-W100N-HT27-02-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. As an axis controller within modular drive racks, it converts command data from a higher-level control into regulated three-phase power for servo motors used in industrial handling cells, machine tools, and packaging lines. This arrangement lets the unit serve as the regulated power stage for a single motion axis inside a larger multi-axis system. It is intended for automated equipment that requires coordinated servo performance rather than simple open-loop motor switching. By supervising velocity, current, and position loops, the controller maintains closed-loop motion accuracy and protects connected motors against overcurrent, short circuit, and thermal overload.
Its command channel is the SERCOS fiber-optic interface, allowing deterministic real-time telegrams between the drive and CNC or PLC nodes. This communication path supports synchronized command execution with the rest of the drive system. Within the DIAX04 controller family, this module is line 03, so it fits the mechanical and electrical format used by related units in the platform. The power stage is rated for 100 A continuous output, so upstream cabinet components must supply matching bus current without excessive voltage drop during sustained axis demand. A built-in air blower moves cooling air through the heat sink, eliminating the need for external ducting while helping keep internal temperatures under control.
The unit is Version 2, which places it in the later revision used for this controller type. The classification HDS Drive Controller places it within a standardized parameter structure used across the series. That structure supports functions such as acceleration feed-forward and current loop gains for closed-loop axis control. These control functions help the drive respond predictably to changing load conditions during acceleration, steady-speed operation, and position correction.
