Product Description:

The HDS02.2-W040N-HS37-01-FW is a drive controller built by Bosch Rexroth Indramat for coordinated multi-axis automation. It belongs to the HDS Drive Controllers series and works within the DIAX04 modular platform to command servo axes through a fiber-optic motion bus. Inside a control cabinet, the unit converts bus commands into regulated current for connected motors, supporting precise velocity and position control on packaging, printing, and handling machinery. Because it is part of a modular drive system, it fits applications that require synchronized motion across several axes without relying on separate standalone controllers for each station.

Communication with higher-level PLCs occurs over the SERCOS interface, so deterministic position data and diagnostic messages travel on a single optical loop at selectable cycle times. The power stage is rated for a continuous output of 40 A, allowing it to energize medium-frame Indramat servo motors without overload. Thermal management is handled by a built-in air blower that draws cabinet air across the heat sink and removes the need for external fans. The housing meets IP 10 per DIN 40 050, which helps prevent accidental contact with live parts but still requires installation in an enclosed rack. During operation, the electronics must remain between +5 to +45 °C so current regulation and component behavior stay stable.

The controller uses insulation class C as per DIN VDE 0110, which supports the dielectric strength expected in this drive category. Proper operation is permitted up to 1000 m above sea level, where cooling air density and insulation margins remain within the intended range. With adequate cabinet airflow, the device can operate at a derated ambient temperature of +55 °C, which gives added flexibility in warmer plant rooms. For transport and storage, it tolerates temperatures from -30 to +85 °C, allowing the unit to be kept in non-climate-controlled spaces before installation. Cabinet ventilation must still be adequate when the controller operates near the upper ambient limit.
