Product Description:

The HDS03.2-W100N-HS78-00-FW is a drive controller produced by Bosch Rexroth Indramat in the HDS Drive Controllers series. The unit regulates power for compatible servo axes in multi-axis industrial machinery, translating commands from higher-level automation equipment into controlled motor voltage and current. This allows closed-loop operation for positioning, speed control, and synchronized axis movement in automated systems. In typical installations, it serves as the power stage between the shared DC bus and the motor, helping the machine respond accurately to changing load conditions during repeated operating cycles.

The controller delivers up to 100 A of output current. This value is the rated current and indicates the maximum continuous line current the device can supply to a connected motor without derating. Command data reaches the control electronics through the SERCOS fiber-optic bus, allowing deterministic communication for synchronized multi-axis moves. The unit belongs to the DIAX04 family, so it can be used with matching modules in the same system architecture. Thermal regulation is handled by a built-in air blower that moves cabinet air across heat-producing components and supports stable internal temperatures. Fiber-optic communication also helps maintain noise-resistant signal transmission in electrically busy cabinets.

The housing is categorized as Line 03, which places the controller in the third design line used for compatible supply and interface modules. The product is version 2, indicating the revision used for this controller type. Its functional designation is HDS Drive Controller, which distinguishes it from supply or I/O units in the same rack. It is intended for use in the HDS rack environment rather than as a standalone supply module. Matching line and version data keep the module aligned with the intended platform configuration.
