Product Description:
The HDS04.2-W200N-HT20-01-FW is a drive controller module produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. The unit serves as a power and control interface for synchronous and asynchronous servo motors in industrial automation cells, coordinating axis movement, speed regulation, and diagnostic data flow with the master motion system. By converting DC-bus energy into regulated phase currents, it supports dynamic motor response while helping protect the drive electronics and connected machinery. This arrangement lets the controller respond quickly to load changes during acceleration, deceleration, and steady-state motion. Typical applications include automated packaging, material handling, and machining centers where closed-loop accuracy and rapid acceleration are required.
The command layer communicates through SERCOS, a fiber-optic serial ring that delivers synchronized setpoints and feedback without the delays of discrete I/O wiring. Within the DIAX04 controller family, this card occupies a single slot and uses a backplane encoder channel to share position data with adjacent drives. A built-in air blower in the heat sink provides forced convection, so the power stage can continuously deliver 200 A of output current without exceeding thermal limits. The drive receives its DC-link energy and logic supply from common power units, and its command interface remains galvanically isolated to reduce electrical noise between axes.
This variant is identified as 04 in the DIAX line numbering system and carries revision index 2. Cooling is managed with internal airflow instead of external cabinet ducting, so air movement stays localized at the power section. The module combines gating electronics, current sensors, and protective relays in one housing. The integrated sensing and protection hardware supports stable current control under changing loads. It is intended for modular drive racks where several axes share common supply resources and exchange position-related data through the system architecture.
