Product Description:

The HDS02.1-W040N-HA44-01-FW is a drive controller manufactured by Bosch Rexroth Indramat within the HDS Drive Controllers series. It belongs to Line 02 and is released as Version 1 for use as the axis power and regulation module in DIAX04 multi-axis systems. In operation, it converts incoming DC bus energy into controlled AC output for servo motors, allowing automated machinery and material-handling axes to run with regulated speed and torque. The unit is intended for cabinet-based drive assemblies where one controller is assigned to a single axis and works with the shared system power structure.

This controller exchanges setpoint and feedback data through an analog command interface, which simplifies wiring and supports legacy motion cards that do not use digital network communication. Continuous load capability is limited by a rated current of 40 A, so upstream fusing and cabling must be matched to that value. Thermal management is provided by a built-in air blower that circulates cabinet air across the heat sink to control semiconductor temperature during sustained operation. Reliable operation is specified for ambient conditions from +5 to +45 °C, and the unit can continue to operate with derating up to +55 °C when cabinet airflow is adequate. The housing has an IP 10 protection rating per DIN 40 050, so it is finger-safe but has no protection against liquids and normally requires installation inside an enclosure.

Installation is permitted at altitudes up to 1000 m above sea level before altitude-related derating is needed, because reduced air density lowers cooling effectiveness. Internal components use insulation class C under DIN VDE 0110, which supports the thermal demands associated with cyclic drive duty. For storage and unpowered transport, the electronics tolerate temperatures from -30 to +85 °C. These limits help determine where the controller can be stored and operated without exposing the power stage or insulation system to unsuitable conditions.
