HDS05.2-W300N-HA25-01-FW
The HDS05.2-W300N-HA25-01-FW drive controller is built by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Within an automated machine cell, this controller meters power to servo axes and executes velocity or position commands supplied by a higher-level control system. Its primary role is to close the current loop for Indramat motors, converting command signals into regulated three-phase output that moves mechanical loads with repeatable accuracy. This allows the drive to respond quickly to changing load conditions during synchronized machine motion. It fits into DIAX04 multi-axis racks, where it shares the same DC bus and communication backplane with neighboring modules.
The unit handles a continuous output of 300 A, so the power section can support high current demand on large servo axes. Incoming motion references arrive over an analog interface, enabling connection to legacy PLC or CNC hardware that transmits ±10 V speed or torque commands. Because the command input is analog, the unit can be integrated into systems that use conventional reference signals instead of digital motion commands. Thermal management is provided by a built-in air blower, which circulates cabinet air across the heat sink without external ducting. The controller follows the DIAX04 family architecture, so its parameter handling and diagnostic behavior remain consistent with other axes on the shared bus system.
The designation 05 identifies the controller line within the range and indicates the mechanical dimensions and connector pinouts used for this unit. The revision code is 2, showing that this is the second design version with component updates that do not alter field wiring. The unit is an HDS Drive Controller, intended for installation as the power and regulation stage in a cabinet-based multi-axis system. Its mounting arrangement and airflow path are matched to the housing so cabinet air can move through the module in the expected direction. This supports stable thermal operation when the controller is installed beside other drive modules in the same enclosure.
