HDS04.2-W200N-HS08-01-FW
The HDS04.2-W200N-HS08-01-FW is a modular drive unit in the HDS Drive Controllers series from Bosch Rexroth Indramat. It regulates servo axes in automated machinery by converting command data from a higher-level motion processor into controlled motor currents. The controller combines power electronics and digital control functions in one chassis, which helps reduce panel space in multi-axis cabinets. Digital logic inside the unit processes command and feedback information so axis motion remains stable during changing loads and repeated production cycles. It is intended for closed-loop velocity and position control in tooling centers, packaging stations, and assembly gantries.
Its communication layer uses the SERCOS fiber-optic bus, so velocity setpoints, diagnostic data, and parameter values are exchanged in real time with neighboring drives. The power section can supply a continuous output current of 200 A, which makes the unit suitable for high-torque axes without exceeding its continuous thermal capacity. The controller is part of the DIAX04 platform, which uses a common mechanical format and standardized connections across the rack. This shared platform keeps module dimensions and interface placement consistent in multi-axis installations. The unit is Version 2, indicating the second design iteration of this model.
Thermal management is handled by a built-in air blower. It channels cabinet air through the heat sink fins during continuous operation, so no external cooling ducts are required for the airflow path. The drive fits position 04 in the rack layout, matching the mechanical keying used for that slot. It is supplied as an HDS Drive Controller and is offered as a standalone axis card for a single controlled axis. That arrangement allows the module to serve one motor winding within a larger coordinated drive assembly.
