Product Description:

The HDS04.1-W200N-HA29-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. In an industrial automation rack, it interprets motion commands, supervises current loops, and sends firing signals to power modules so servo motors follow programmed profiles. As part of the DIAX04 platform, it works with companion supply sections on a common backplane to coordinate several axes from one control system. Because control and power functions are separated within the rack, the module fits multi-axis installations where supply sections and controllers are grouped in a compact cabinet. This layout suits machines that need centralized drive electronics for synchronized motion and high power handling.

Command processing relies on an analog interface, so the controller responds to ±10 V setpoints from motion cards or PLC modules. This input style is useful in systems that use analog motion cards instead of networked fieldbus commands. Inside the product line, it is identified as Line 04, which keeps its mechanical and electrical format consistent with matching supply modules. The continuous current drawn from the shared DC bus can reach 200 A, making the unit suitable for demanding servo applications with sustained load. Thermal management is handled by a built-in air blower that circulates cabinet air through the heat sink instead of requiring external ducting. The command voltage is sampled by a 12-bit converter, which supports fine resolution for speed and torque control.

The unit is Version 1 and is supplied as an HDS Drive Controller. It does not include optional safety or communication add-ons, so any extra system functions must be provided by external modules in the drive rack. Front-panel status LEDs provide a visual indication of operating state and fault conditions during operation. The controller remains focused on axis regulation, current control, and coordination with the surrounding power hardware.
