Product Description:

The HDS03.2-W075N-H is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series within the DIAX04 family. It is an HDS drive controller intended for use in multi-axis racks, where it supplies the power stage and closed-loop control functions required by servo and spindle motors. In automated production cells, the unit regulates current, velocity, and position loops so connected axes can respond accurately to motion commands during conveying, packaging, and handling tasks. Because it operates as a rack-mounted drive module rather than a stand-alone unit, it works within a coordinated system that shares DC-bus power and command data across several axes.

This controller has a rated output of 75 A for normal operation. At a PWM switching frequency of 4 kHz, it can deliver 40 A continuously, and the permissible continuous output falls to 30 A when the switching frequency is raised to 8 kHz. Internal thermal losses at continuous current amount to 220 W, and an integrated air blower removes this heat without external ducting. Protection is rated IP 10 according to DIN 40 050, insulation is class C per DIN VDE 0110, and the control section uses 25 W of signal-processing power. In the DIAX04 family, the unit is Line 03 and Version 2.

Operation is permitted between +5 °C and +45 °C, and derating allows limited service up to +55 °C. For shipping or long-term storage, the unit tolerates temperatures from -30 °C to +85 °C, and full performance is maintained at installation heights up to 1,000 m above sea level. The controller weighs 11 kg, which should be considered when planning panel support and handling. Cabinet layout must also allow space for airflow from the built-in cooling system and for the depth of the mounted module in the rack.
