HDS05.2-W300N-HT12-01-FW
The HDS05.2-W300N-HT12-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. As a modular power section, it supplies regulated three-phase energy to servo drives in multi-axis machines, enabling coordinated motion in industrial automation. It interfaces with common DC-bus supply modules and executes closed-loop positioning sequences commanded by the machine control. In this role, it converts bus energy into controlled motor current so connected axes can follow speed, torque, and position commands with repeatable response. This makes it suitable for machine platforms that coordinate several servo axes from one supply structure.
The controller exchanges motion commands through the SERCOS fiber-optic bus, allowing deterministic communication between the numerical control and the drive. Its power circuitry can deliver a continuous output of 300 A, a current capacity intended for large-torque motors and other high-demand axis applications. Thermal management is handled by a built-in air blower, which moves heat through the unit’s heat sink channels without relying on separate cabinet fans. As part of the DIAX04 controller family, this model shares common backplane dimensions and connector pinouts with related modules. The unit is an HDS Drive Controller for modular multi-axis drive systems.
The unit is part of Line 05 and is listed as Version 2. Power wiring uses top-edge power terminals, while control wiring uses front-mounted signal connectors to keep connections separated on the cabinet face. This arrangement supports organized cable routing in dense drive panels and leaves the signal interfaces easy to reach. The rack-based layout also suits installations that use a shared DC bus with coordinated servo axes operating side by side. Separating the power and signal entry points also helps keep high-current conductors away from low-level control connections inside the panel.
