Product Description:

The HDS03.2-W100N-HS79-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It mounts in a DIAX04 automation rack and supplies regulated power and motion commands to servo and spindle axes on factory equipment. The controller converts higher-level motion requests into controlled current and velocity references so connected motors can follow commanded paths with accurate response. This type of unit is suited to machines that require coordinated axis movement, including packaging systems, transfer equipment, and machine tools.

Its command channel is the SERCOS optical bus, allowing deterministic 2 ms update cycles between the controller and the motion coordinator. The power stage delivers a continuous output of 100 A, so associated supply modules and motor conductors must be rated for the same current level. Thermal management is handled by a built-in air blower that directs airflow across the heat sink instead of relying on external cabinet fans. Fiber-optic communication also helps reduce sensitivity to electrical noise in high-power inverter cabinets. If heat builds beyond the target operating range, the controller reduces output to protect the IGBT power section.

This unit is assigned to Line 03, which places it within the corresponding product line of the platform. It is built as Version 2, using updated gate-drive components while maintaining the general electrical interface used for compatible system layouts. Within the rack, the controller is used for closed-loop regulation of current, velocity, and position on multi-axis equipment. Its optical communication path also allows additional drives to be integrated into the same control network without changing the basic method of synchronized data exchange. That helps maintain coordinated operation when several axes share a common motion system.
