Product Description:

The HDS02.2-W040N-HS78-00-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Designed for multi-axis automation, it belongs to the DIAX04 controller family and converts SERCOS telegrams into regulated current for servo motors. Within an installation, the unit forms the central power and control element, coordinating motion sequences and monitoring feedback to maintain precise tool or conveyor speeds. It handles diagnostic reporting, parameter storage, and protective shutdowns during operation.

The controller exchanges real-time commands over the SERCOS optical ring, eliminating electrical noise between the drive cabinet and a CNC or PLC. Internal heat is removed by a built-in air blower, so no external ducting is required inside the enclosure. During operation, the power section can supply up to 40 A of continuous drive current, matching medium-frame synchronous or asynchronous motors. Protection against accidental contact is limited to IP 10 as defined in DIN 40 050, so the unit must be mounted in a closed control panel. Reliable operation is specified for ambient air between +5 ... +45 °C, allowing placement beside other warm equipment without derating.

At ambient temperatures up to +55 °C, drive output must be derated to stay within component limits. Installation is permitted up to 1000 m above sea level, after which cooling air density becomes too low for the blower. Windings and power semiconductors carry a Class C insulation rating in accordance with DIN VDE 0110, supporting elevated internal temperatures during repetitive braking energy. When stored or shipped, the components tolerate ambient values from −30 ... +85 °C. The device is part of Line 02 and is Version 2.
