Product Description:

The HDS02.2-W040N-HA27-01-FW is a drive controller manufactured by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. The device serves as the power stage between motion-control electronics and servo motors, converting low-level command signals into regulated three-phase output for closed-loop positioning and speed regulation. Because it works as the intermediate power stage, it translates control demand into motor current with the response needed for synchronized axis motion. It is intended for multi-axis machinery where rapid response, coordinated braking, and accurate torque delivery are needed during repetitive production cycles in assembly lines, material-handling systems, and machine tools.

Control instructions reach the unit through its analog interface, so incoming voltages proportional to speed or torque are interpreted directly by the control section. This arrangement supports systems that use analog setpoints instead of a digital communication link. The power stage can deliver a continuous output of 40 A, which suits medium-frame servo motors used in grouped axis applications. Thermal management relies on a built-in air blower that moves cabinet air across the heat sink to control semiconductor temperature during sustained operation. The enclosure has an IP 10 rating, so the controller should be installed inside a clean cabinet rather than in an exposed location. For reliable operation, the permissible ambient temperature range is +5 to +45 °C, and higher surrounding temperatures require output derating.

At installation heights up to 1000 m above sea level, the controller maintains full current capability without extra cooling measures. Its insulation system meets class C under DIN VDE 0110, which supports the electrical isolation required in the drive section. Within the DIAX04 family, the unit is part of line 02 and version 2. If cabinet airflow is reduced or the load remains high, the controller may continue operating with reduced output once the heat sink reaches +55 °C. Storage and transport temperatures from -30 to +85 °C help protect the electronics during handling and shipment.
