Product Description:

The HDS05.2-W300N-HS27-01-FW is a modular digital drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It is installed in drive racks to provide closed-loop regulation and power conversion for synchronous and asynchronous servo axes. The unit acts as the power and control stage between the DC bus supply and the connected motors. In automated machining centers and material-handling stations, it converts incoming DC bus energy into controlled motor currents so that velocity, torque, and position stay within commanded limits during operation. That control approach helps the machine follow speed and position commands during acceleration, steady motion, and deceleration.

Communication with the higher-level PLC is handled through SERCOS, which allows deterministic exchange of setpoints, feedback, and diagnostic data. This supports synchronized command execution across multiple axes in the same machine section. As part of the DIAX04 platform, the controller fits multi-axis rack systems that use a shared DC bus and coordinated axis control. Thermal management is provided by a built-in air blower, which moves heat out through the front exhaust openings. The power section is rated for a continuous current of 300 A, supporting high-torque servo applications and sustained load demand across connected axes.

The drive is identified as Version 2. It uses rack position code 05, which provides the installation width required for this current class in the rack and leaves room for the corresponding busbar connection. This arrangement suits multi-axis systems that distribute power over a common DC link and coordinate several servo axes from one control architecture. Its layout also keeps electrical and cooling connections aligned with the surrounding rack modules used in the same system. The combination of rack placement and current capacity fits larger servo channels that need more space than lower-current modules.
