Product Description:

The HDS02.1-W040N-HA03-01-FW is a drive controller manufactured by Bosch Rexroth Indramat within the HDS Drive Controllers series. As a member of the DIAX04 family, this Version 1 unit functions as the central power stage for servo axes in industrial automation. It converts incoming three-phase energy into regulated motor current so that connected axes can follow positioning and velocity commands with high precision. In a multi-axis cabinet, it serves as the link between the power supply and the servo motor while supporting stable torque and speed control during changing load conditions.

The controller delivers a rated output of 40 A, so its power section can continuously supply that current to matched motors without exceeding thermal limits. Command values are accepted through an analog interface, allowing integration with PLCs or motion cards that provide ±10 V signals. This arrangement suits systems that use analog command signals instead of a digital fiber-optic network. Internal heat is removed by a built-in internal air blower, which keeps component temperatures within range without requiring extra cabinet fans. The housing has a protection class of IP 10, so it must be installed in a closed electrical cabinet. Reliable operation is permitted at ambient temperatures from +5 to +45 °C, where the controller can maintain normal current output without derating.

Continuous operation is allowed up to an elevation of 1000 m above sea level before cooling performance must be reconsidered. If cabinet temperature rises above the normal operating range, the unit can still be used up to +55 °C when the load is reduced. For storage and transport, the electronics can withstand temperatures from -30 to +85 °C while the unit is not energized. The insulation system meets Class C per DIN VDE 0110, which supports higher internal temperature tolerance than lower insulation classes.
