Product Description:

The HDS03.2-W100N-HT78-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. In an automation cell, the module conditions bus commands, regulates motor currents, and processes encoder feedback to keep servo axes synchronized with the machine sequence. It mounts on a common backplane with supply units and neighboring axis cards, creating a compact motion package for multi-axis equipment such as printing presses, pick-and-place stations, and conveyor networks. This arrangement helps centralize drive functions inside one cabinet section and supports coordinated motion where several axes must respond to the same control system at the same time.

A fiber-optic interface compliant with SERCOS links the controller to the central PLC, exchanging position, velocity, and diagnostic data during each cycle. The unit is part of the DIAX04 family, so its mounting pitch and bus connectors match other cards in that platform. Thermal limits are managed by a built-in air blower that directs cabinet air across the IGBTs without requiring an external fan. Under continuous load, the power stage delivers 100 A, allowing it to drive high-torque servomotors in demanding multi-axis systems. The optical link also helps maintain stable communication in cabinets where electrical noise from power switching can be present.

The controller is Version 2 and is part of Line 03. It also includes diagnostic LEDs and supports memory cards for local status indication and parameter handling. These features keep operating information accessible at the drive and help retain parameter data within the control platform. Because the unit remains focused on current, speed, and feedback processing inside the rack, it can serve as a dedicated axis controller alongside matching supply and interface modules.
