Product Description:

The HDS04.2-W200N-HS98-01-FW is a modular drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It supplies regulated power to servo axes in automated assembly, packaging, and material-handling equipment. Acting between the motion controller and the motor windings, it converts command data into controlled current so coordinated speed and torque profiles can be maintained across multi-axis machinery. This role gives the drive a fast electrical response during acceleration, deceleration, and load changes. It is suited to production systems that require synchronized axis movement and stable current regulation during continuous operation.

Data exchange takes place over the SERCOS fiber-optic interface, so cyclic position and velocity commands reach the drive with deterministic timing. As part of the DIAX04 family, it fits rack-based systems that use the same control platform across multiple axes. Thermal management is handled by a built-in air blower that moves cabinet air through the heat sink without separate ducting. Airflow across the heat sink removes switching losses from the power electronics during prolonged duty cycles. The power stage is rated for 200 A continuous output, which supports high-inertia starts and sustained torque demand. Deterministic communication also helps the controller follow synchronized motion commands without irregular update delays.

The unit is Version 2 in this product line. The designation 04  indicates the mechanical frame size and sets the mounting hole pattern and connector spacing. It operates as the power section in a two-component drive arrangement, where a separate command module handles higher-level control functions. The frame size also determines the physical envelope used in the cabinet. Separating the command stage from the power stage keeps control processing and power conversion in dedicated sections within the same drive system.
