Product Description:

The HDS04.1-W200N-HS70-01-FW is an AC drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. Installed in a DIAX04 rack as the power stage for servo motors, it converts commanded setpoints into regulated output current for the connected axis. This arrangement lets the controller manage acceleration, deceleration, and closed-loop motor response for machine sections that require coordinated motion. Because current regulation takes place inside the drive, the connected servo motor can follow speed and torque commands accurately during indexing, interpolation, and other repeated motion tasks. It is suitable for packaging, printing, and material-handling systems where axis response must remain stable through frequent load changes.

Command data reaches the controller over the SERCOS fiber-optic bus, allowing deterministic timing between the master and the drive during cyclic motion control. The unit can supply up to 200 A of continuous output current, which supports demanding servo axes without immediate thermal derating. Heat produced by switching losses is removed by a built-in air blower, so the heat sink can remain within its intended operating range during sustained use. The communication link also returns status information to the higher-level control, which helps the machine maintain synchronized motion across multiple axes. This self-contained cooling method supports installation in dense multi-axis cabinets where controlled internal airflow is important.

The device is identified as an AC drive controller used in modular motion systems with multiple coordinated axes. It is part of Line 04 and is built as Version 1, indicating the product generation for this model. The drive works as the rack-mounted current control stage between the motion command source and the connected motor, helping the axis respond accurately to changing process demands. Its modular format suits machine tools and transfer systems that group several axes in one control cabinet while keeping each motor channel on a dedicated power module. This layout also supports organized system expansion when additional axis modules are installed beside the controller.
