Product Description:
Bosch Rexroth Indramat produces the HDS02.1-W040N-HS91-01-FW as part of the HDS Drive Controllers series. Within multi-axis DIAX04 drive systems, this unit functions as the axis controller that converts digital motion commands into regulated current for the connected power section. It bridges motion profiles issued by a CNC or PLC to the analog demands of servo motors used in material-handling, packaging, and machining cells. Because the controller manages axis-level regulation, the connected motor can respond smoothly to changing speed and torque demands during automatic operation. This role makes it suitable for coordinated axes that must follow precise acceleration, deceleration, and positioning profiles across repeated machine cycles.
The communication backplane accepts the SERCOS fiber-optic ring, matching the controller to networked drives that require deterministic update cycles. Thermal management is handled by a built-in air blower, and the fan draws air vertically through internal channels so no external heat sink is needed. Protective design meets IP 10 per DIN 40 050, which guards against accidental contact while allowing the airflow needed by the cooling path. The current loop is sized for a continuous output of 40 A, enabling the module to drive medium-power servomotors without additional external amplifiers. The unit is part of Line 02. Insulation class C per DIN VDE 0110 applies to the internal insulation system and supports operation at elevated internal temperatures.
Installation is permitted up to 1000 m above sea level without performance derating. Normal operation is permitted within +5 to +45 °C, and the ambient limit rises to +55 °C when the output stage is reduced. During shutdown or shipping, the electronics tolerate ambient conditions from -30 to +85 °C, which helps protect the unit when it is stored in unpowered equipment. Altitude and ambient temperature both affect cooling air density and heat removal, so these limits should be observed during installation and operation.
