Product Description:

The HDS03.1-W100N-HS56-01-FW is a modular drive controller produced by Bosch Rexroth Indramat and part of the HDS Drive Controllers series. It supplies regulated current to servo and main drives and coordinates axis movement in automated machinery and production lines. Its modular design supports installation with separate power sections, so the control section and power hardware can be arranged within the same rack. In multi-axis systems, it connects through a shared DC bus, allowing spindle, servo, and auxiliary axes to operate from a common energy source. This arrangement supports coordinated motion across packaging lines, transfer systems, and other machines that use several controlled axes at once.

Communication with higher-level control occurs over the SERCOS optical ring, providing deterministic data exchange for drive parameters and cyclic motion commands. The power stage delivers 100 A continuously, so large servo motors can accelerate without exceeding thermal limits during sustained operation. A built-in air blower moves cabinet air across the heat sinks, removing heat without external fans or liquid cooling. Within the DIAX04 platform, the module uses the same backplane format as companion axes, which helps it fit standardized multi-axis assemblies. It is classified as an HDS Drive Controller for servo and main drive applications.

The device is part of Line 03, which identifies the third design line used for this model. It is released as Version 1. These identifiers distinguish the module revision and the parameter structure used by this controller. They also correspond to the diagnostic format and control behavior associated with this release. The revision information is useful when matching the controller with associated feedback and supply modules in the same platform.
