HDS03.2-W100N-HA04-01-FW
The HDS03.2-W100N-HA04-01-FW is a drive controller developed by Bosch Rexroth Indramat for the HDS Drive Controllers series. It operates as a control module in a modular drive rack, working with power supplies and servo inverters to deliver regulated current to brushless and induction motors used in machining centers, printing presses, and assembly lines. By converting reference signals from an external automation system into high-speed switching commands, the unit governs motor torque and position for coordinated multi-axis motion. This role allows the controller to support precise axis response in systems that depend on stable closed-loop operation. Its compact housing also supports dense cabinet layouts where several axes must fit in limited panel space.
Command data reach the module through an analog interface, so velocity, torque, or position commands can be supplied as ±10 V differential signals. The analog command path suits control systems that provide continuous reference values instead of serial communication to the drive. The unit belongs to the DIAX04 platform, which uses a common backplane format and consistent module geometry across related controllers. The power stage provides a continuous output of 100 A, and internal protection circuits supervise phase current during operation. The unit is part of Line 03, which matches it to the corresponding mechanical arrangement used by companion HDS modules.
Thermal load is managed by a built-in air blower, so the controller can remove heat without depending on separate cabinet fans. This airflow helps maintain component temperature during rapid current changes and sustained duty. The unit is Version 2 and uses the diagnostic message set assigned to that release. It can be paired with HMS power supplies in the same rack without additional adaptation, which supports a consistent modular layout. The controller therefore fits applications that require steady current regulation and reliable response across multiple coordinated axes.
