Product Description:

The HDS03.1-W075N-HA27-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Positioned in the DIAX04 modular drive family, it links a higher-level motion processor with servo power stages. It provides coordinated current, velocity, and position regulation for automated assembly lines, printing presses, and material-handling stations. It is intended for closed-loop servo applications that require repeatable positioning and stable response under changing load conditions.

The unit exchanges setpoint and feedback data through an analog command interface, allowing straightforward pairing with legacy PLC cards as well as modern analog motion controllers. This interface is suited to systems that issue velocity or torque commands as analog reference signals. Thermal management relies on a built-in air blower that channels cabinet air across the heat sink, eliminating the need for external ductwork. A continuous output capability of 75 A supports medium-power servo axes such as gantry drives or spindle motors. The controller delivers full rated current in ambient temperatures from +5 to +45 °C. Its housing carries a rating of IP10 under DIN 40 050, so it must be mounted inside a protected electrical enclosure to reduce accidental contact and dust entry.

Mounting is permitted up to 1000 m above sea level before current derating is required. The power section uses a C insulation class scheme under DIN VDE 0110, allowing higher temperature tolerance than Class B systems during short overloads. During storage or shipment, components remain stable from -30 to +85 °C. A derated operating ceiling of +55 °C allows use in warmer facilities at reduced current, and the product is identified as Line 03 and Version 1. These limits cover installation, storage, and operation in enclosed industrial equipment.
