Product Description:

The HDS04.2-W200N-HT10-01-FW is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It functions as a central converter section that conditions the shared DC bus for multiple servo axes, supplying each downstream inverter with stabilized power and supervisory logic for coordinated axis operation. In automated machining centers and material handling cells, the unit links higher-level motion commands to the motor-side power stage so coordinated acceleration, velocity regulation, and position control can be maintained across the installation. Because several axes can share the same bus structure, the controller supports grouped motion sequences where acceleration and speed changes must stay consistent from axis to axis.

The controller exchanges cyclic setpoints and status words over the SERCOS fiber-optic interface, allowing deterministic communication with a PLC or CNC kernel during tightly timed motion cycles. Internally, thermal management is handled by a built-in air blower, which moves cabinet air across the heat sink so rated output can be maintained without external ducting or a separate fan assembly. A continuous output capability of 200 A is the maximum current available to attached drives, so connected power stages must be sized within that limit during continuous operation. The hardware is assigned to Line 04, which indicates dimensions and connector placement used within that line, and it is grouped in the DIAX04 family so it matches the platform layout used by related modules in the same system.

This unit is released as Version 2. It is an HDS drive controller rather than a stand-alone inverter, so it must operate with separate HVE or HVR power supplies and individual HDS axis modules instead of serving as a complete drive package by itself. The modular arrangement separates the incoming supply section from the axis-specific power stages, which allows the controller to serve as the central coordination point in a multi-axis system. This layout keeps the power architecture organized when several servo axes are installed in the same cabinet and connected through a common DC bus structure.
