Product Description:

The HDS04.2-W200N-HT21-01-FW is an axis drive module from Bosch Rexroth Indramat. It is used in multi-axis industrial automation systems to supply regulated power to servo and main spindle motors while exchanging real-time motion commands with higher-level controls. In a machine cabinet, it serves as the power conversion stage between the supply section and the motor, helping the axis respond to speed and torque commands with stable control. This makes it suitable for coordinated motion tasks that require accurate response across several connected axes.

This controller communicates over SERCOS through a fiber-optic link, allowing command and diagnostic data to move between the drive, PLCs, and connected motors with consistent timing. It is part of the DIAX04 family, so it fits mechanically and electrically into DIAX04 racks without additional adapters. Thermal management is handled by a built-in air blower; the fan pulls air through the heat sink and directs it toward the rack exhaust path without external ducting. The power stage is rated for 200 A continuous output, which allows the module to support large-frame servo motors or smaller motors connected in parallel. The product is part of Line 04 in the platform, which identifies this design line within the series.

This unit is cataloged as Version 2, indicating a later revision of the control hardware for this model. It uses flash memory, which stores operating data in nonvolatile form and allows software updates when required. The controller remains compatible with existing rack infrastructure, so it can be installed in systems that already use related HDS modules. Its electrical interface and airflow path are matched to the surrounding drive assembly, which helps the module operate properly within cabinet-based motion systems.
