HDS05.2-W300N-HS93-01-FW
The HDS05.2-W300N-HS93-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Installed in a DIAX04 multiaxis rack, it serves as the power stage that converts digital motion commands into regulated three-phase output for servo motors. The controller manages position, speed, and torque loops so axes can follow coordinated motion profiles in machining centers, packaging equipment, and material-handling gantries. Regulated output current helps the connected motor respond predictably during acceleration, deceleration, and holding tasks. Its modular format also allows it to operate beside matching supply and control units in the same rack.
Its communication backbone is the SERCOS fiber-optic interface, which provides deterministic cycle times and electrical isolation between the motion master and the drive. The optical link also helps maintain reliable data exchange in cabinets where power electronics and motor cables operate nearby. The controller supplies up to 300 A of continuous output current, giving it the capacity needed for high-torque motor families and demanding axis loads. Thermal stability is maintained by a built-in air blower that forces air across the heat sink, so external ducting is not required. This cooling method supports steady operation when the unit is installed in tightly packed drive assemblies.
The unit belongs to Line 05, which sets the housing size and connector layout for this design. It is produced as Version 2, reflecting a later revision of the controller. The product is classified as an HDS Drive Controller, and its control interface follows the standard enable, fault, and status word structure used across the platform. The housing and connector placement allow the module to sit directly beside companion units without changing the basic rack arrangement. The cabinet can use a common ventilation path for adjacent modules, which helps keep the power section within its intended operating range.
