Product Description:

The HDS05.2-W300N-HS26-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat. It functions as the axis amplifier in multi-axis motion systems, converting command data from higher-level control hardware into regulated current for connected servo drives. Because the controller regulates current directly at the axis, it can respond to motion commands and load changes during operation. In an automation cell, it coordinates speed, torque, and position loops so that gantries, tooling stations, and transfer lines follow programmed trajectories with precision.

A key link to the supervisory control layer is the SERCOS optical interface, which carries deterministic cyclic telegrams and real-time motion commands. Optical communication also helps maintain stable data transfer in electrically active cabinets. The unit is part of the DIAX04 family, so it shares mechanical and electrical compatibility with companion supply and feedback modules and can operate on a common DC bus. The controller can deliver a continuous output of 300 A, which is the rated motor phase current available without derating. That current capacity suits large servo axes that require sustained torque under continuous production duty. Thermal management is handled by a built-in air blower, so external ducting is not required to remove switch-loss heat.

The unit is part of Line 05, which indicates the backplane size and connection geometry used in this generation. Its form factor matches related modules installed in the same rack, which keeps integration consistent across the drive system. It is released as Version 2. Classified as an HDS Drive Controller, it uses the same mounting pattern and bus rail arrangement as related modules in the series. The shared geometry supports synchronized operation across multi-axis systems and keeps the controller matched to surrounding hardware.
