HDS03.2-W100N-HT12-01-FW
The HDS03.2-W100N-HT12-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and positioned as an axis module within the HDS Drive Controllers series. It supplies regulated DC bus power and closed-loop control to servo motors used on automated production equipment. By controlling motor speed, torque, and position, the unit forms the interface between higher-level motion commands and the electromechanical load, allowing coordinated multi-axis movement in applications such as pick-and-place systems, conveyor synchronization, and web tension control.
Its command layer relies on the SERCOS real-time fiber-optic ring, allowing deterministic exchange of setpoints, feedback, and diagnostics with CNC or PLC hosts. The controller belongs to the DIAX04 family, so its form factor and connector layout match other modules in the same rack. Thermal management is handled by an internal air blower that draws cabinet air through the heat sink, so no external heat exchanger is required. The power stage is rated for 100 A, giving the unit enough output current for medium-to-large permanent-magnet or induction servo motors. The module is part of Line 03, and the unit is Version 2.
The HT12 option supports high-resolution position-loop operation for applications that need accurate axis response. This module can operate on a shared DC bus with adjacent drives, so energy returned during braking can be used elsewhere in the drive group instead of being dissipated immediately. The controller extends axis count without changing cabinet depth, and the optical command connection supports orderly integration into larger multi-axis systems. In operation, it helps keep commanded motion profiles consistent during synchronized machine sequences by processing feedback and applying closed-loop correction as load conditions vary.
