Product Description:

The HDS05.2-W300N-HS78-00-FW is an axis drive controller manufactured by Bosch Rexroth Indramat within the HDS Drive Controllers series. Used with a common supply unit, it modulates motor current and voltage so compatible servomotors follow velocity or position commands from a higher-level CNC or PLC. This supports precise torque control in metal-cutting equipment, packaging systems, and automated assembly lines where several axes must respond in a coordinated manner. Because regulation occurs at the axis level, the controller can react quickly to load changes and command updates during repetitive production cycles.

This drive communicates with motion processors through the SERCOS optical ring, allowing synchronous setpoint exchange and diagnostic feedback over fiber with deterministic timing. The optical link also returns status information without conventional copper signal wiring between modules. It belongs to the DIAX04 controller family, so it can share a DC bus and cabinet airflow arrangement with other modules installed in the same rack. Thermal control is handled by a built-in air blower that pulls cabinet air through the heat sink to limit semiconductor temperature during sustained load changes. The current loop supports applications that require up to 300 A of rated output, so the associated conductors, busbars, and protective devices must be sized for that continuous demand.

The product is part of Line 05 and uses the mechanical layout and connector style assigned to that line. The unit is Version 2. As an HDS Drive Controller, it closes the current, velocity, and position loops locally while the central control system supplies operating parameters and motion profiles. This arrangement lets the higher-level controller focus on axis coordination while the drive manages fast internal regulation on the machine. That division of control helps maintain stable response during rapid speed changes, contouring moves, and repeated start-stop cycles in automated equipment.
