Product Description:

The HDS04.2-W200N-HS26-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It coordinates torque and velocity loops for servo and main spindle drives, allowing a host CNC or PLC to manage axis motion over a fiber-optic control network. In machine installations, the unit works as the axis amplifier that converts high-level motion commands into regulated motor current. This operating role supports controlled acceleration, steady running speed, and repeatable response when the driven load changes during production. It can be used in automated handling systems, process lines, and spindle applications where the machine controller must coordinate several axes at once.

Communication relies on SERCOS, so position, velocity, and diagnostic data move through deterministic real-time optical communication. Optical transmission also reduces sensitivity to electrical noise around high-power equipment. The controller is part of the DIAX04 platform, which uses shared mechanical dimensions across related modules and supports consistent installation within multi-axis racks. Its continuous busbar supply can deliver up to 200 A of output current, allowing the module to drive large torque motors or high-inertia spindles without external current boosters. Thermal management is provided by a built-in air blower, which moves air across the heat sink to control semiconductor temperature during sustained load.

Configuration details place the module in Line 04, and the electronics are identified as Version 2. The controller is designed for systems with a common power supply section, so it serves as the dedicated axis unit in multi-axis drive assemblies. This arrangement separates shared power conversion from individual axis regulation, which is typical in DIAX04-based cabinets. It is suitable for machines that already use a central supply module and need a controller dedicated to one motor axis.
