Product Description:

The HDS02.2-W040N-HT76-02-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within a DIAX04 multi-axis system, it supplies regulated DC power and motion commands to connected servo drives. This arrangement supports coordinated positioning and speed control on automated machinery and production lines where several axes must respond to synchronized commands. In this role, the controller serves as the interface between the higher-level motion system and the connected motor axis hardware.

This controller exchanges setpoint and status data through the SERCOS fiber-optic interface, which provides deterministic communication for real-time drive coordination. The optical link supports stable data transfer in systems where timing between axes is important for path accuracy and repeatable cycle movement. Its power stage is rated for 40 A continuous output, so servo axes drawing up to that current can operate without external boosters. Thermal management is handled by a built-in air blower, which pulls cabinet air through the heat sink to keep semiconductor temperatures within limits during sustained load. Installation is allowed up to 1000 m above sea level. The insulation system is classified as C under DIN VDE 0110, allowing the windings and bus bars to tolerate elevated operating temperatures during repeated duty cycles.

Continuous duty is permitted between +5 to +45 °C. Beyond that range, the unit remains functional but may require current derating until cabinet air reaches no more than +55 °C. During storage or shipment, the electronics can withstand -30 to +85 °C. The enclosure has a protection rating of IP 10, so the controller must be mounted in a closed electrical cabinet that limits accidental contact while still allowing the airflow required by the internal cooling system. Because of this housing style, the unit is intended for protected control-cabinet installation rather than direct exposure on the machine frame.
