Product Description:

The HDS03.2-W075N-HA06-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. This module is installed in DIAX04 multi-axis racks where it acts as the central power stage and axis interface. By modulating the current delivered to connected servomotors, it enables accurate position, velocity, and torque control in automated machining centers, transfer lines, and material-handling systems. Its design integrates command processing, power electronics, and protective monitoring to support continuous duty in production environments that require synchronized motion.

Belonging to the DIAX04 controller family, this model exchanges setpoint and feedback values through an ANALOG command interface. This permits direct summing or scaling of velocity and torque references from legacy PLC hardware without digital protocol conversion. A continuous output capability of 75 A is the maximum motor phase current it can regulate under rated ambient conditions, so peak demand must remain within this value. Thermal management relies on a built-in air blower, which circulates cabinet air across the heat sink and eliminates the need for external ducting. The designation line 03 places the unit in the 30 kW power bracket within the family’s standardized mechanical footprint.

Hardware revision 2 updates the internal layout to reduce switching losses while remaining compatible with earlier releases. The unit remains part of the HDS Drive Controllers platform and uses the standardized module format found across the Bosch Rexroth Indramat motion system. That common format supports installation in existing multi-axis racks without changing the basic cabinet arrangement. The suffix FW indicates that the operating functions depend on the installed software package, which governs parameter handling and drive behavior.
