Product Description:

The HDS02.2-W040N-HS70-01-FW is a drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. As a drive controller, it supplies regulated power to connected servo or spindle motors so they can follow motion commands from a higher-level automation system. In a multi-axis DIAX04 rack, it occupies one slot and closes the control loop for its axis, translating digital setpoints into motor current and feedback signals for coordinated machine operation. This arrangement supports synchronized motion in machine tools, packaging systems, and other automated production equipment.

This model communicates through the SERCOS fiber-optic interface, allowing deterministic telegram exchange with the motion CPU. Thermal management is handled by a built-in air blower, which draws cabinet air across the heat sink so full output is available without external ducting. The unit can deliver a continuous output of 40 A, a value used when selecting compatible motor cables and upstream protection. Its enclosure has a protection category of IP 10, so the controller must be mounted inside a cabinet to limit exposure to larger solid objects and accidental contact. Normal operation is specified for ambient temperatures from 5 to 45 °C, which helps the power section remain within its intended thermal range. Because cooling air is drawn from the cabinet interior, the enclosure needs enough free space for steady airflow around the heat sink area.

The controller can be installed at elevations up to 1000 m above sea level without current reduction. If the cabinet air rises above 55 °C, the output must be derated to protect the semiconductor components from excess heat. During shipping or storage, the unit tolerates temperatures from -30 to 85 °C, which helps prevent damage during seasonal transport and warehouse exposure. Internal clearances and insulating materials meet class C according to DIN VDE 0110. The insulation system supports the electrical spacing used inside the controller under normal industrial conditions. The unit uses DIAX04 backplane connectors shared across the HDS02 line, which supports the required mechanical fit in compatible racks.
