Product Description:

The HDS04.2-W200N-HA32-01-FW drive controller is produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. As a servo amplifier module, it coordinates torque, speed, and position loops for AC servo motors in multi-axis systems used in machine tools and automated handling cells. It receives setpoint data from a higher-level motion control device and converts DC bus energy into precisely timed three-phase output patterns for the connected motor. The output stage regulates motor current to support commanded acceleration, steady-state speed, and controlled positioning on conveyors, gantries, and machining axes without external motor starters or contactors.

The unit delivers a maximum continuous output of 200 A, so the power section can drive large-torque motors without derating when the bus voltage is maintained at the rated level. Motion commands enter through the analog interface, meaning the controller expects differential voltage references rather than fieldbus telegrams, which suits legacy CNCs and simple PLC loops. It belongs to the DIAX04 controller family and installs on the shared DC link and communication backplane used by other axes in that platform. Thermal energy is removed by a built-in air blower that forces cooling air across the IGBT heat sinks. The unit is part of Line 04, which indicates the module layout used for this version.

The unit is identified as Version 2 and uses updated gate-drive electronics that match later supply infeed units released for the same platform. It is classified as an HDS Drive Controller, so it serves the power conversion role rather than supplying logic or regenerative functions. Connector coding and parameter structure remain consistent with other motion components in the same platform, which helps keep system integration orderly. This layout lets the controller operate beside companion axes on the same platform without requiring a separate standalone drive housing.
