Product Description:

The HDS02.1-W040N is a drive controller produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. This unit provides closed-loop regulation for associated servo power modules, receiving reference commands from a CNC or PLC and issuing precise control signals for motor torque, speed, and position. By managing these values in real time, the controller supports coordinated multi-axis motion in packaging equipment, material-handling cells, and light machining centers. Feedback processing within the controller helps the connected axis correct deviations during acceleration and steady operation.

Its thermal management relies on a built-in internal air blower, which moves heat away from the power electronics without requiring additional panel fans. The power stage is rated for 40 A of continuous output, which sets the current available to the downstream drive section during sustained operation. Reliable operation is permitted within an ambient range of +5 to +45 °C, and operation within this range helps avoid thermal derating. The housing has an IP 10 rating under DIN 40 050, so it protects against contact with large objects but still requires installation in an enclosed cabinet. Windings and internal wiring use Class C insulation per DIN VDE 0110, which supports higher thermal tolerance than lower insulation classes.

Continuous duty is permitted up to 1000 m above sea level, and installations above that height may require additional cooling or reduced load. If the ambient temperature briefly rises to +55 °C, the controller can still operate with load reduction. During transport or long-term storage, components can withstand temperatures from -30 to +85 °C without damage to the stored unit. The unit is part of Line 02, and it uses the connector layout and diagnostic interfaces common to that design line.
