Product Description:

The HDS03.1-W075N-HS23-01-FW is an HDS Drive Controller manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Within an automation cell, it connects power modules to servo motors and executes motion commands transmitted through the DIAX04 control platform so that axes follow precise velocity and torque references. As a drive controller, it conditions DC bus energy, monitors feedback, and issues switching patterns that keep motor currents synchronized with the commanded trajectory.

Its continuous output capability reaches 75 A, providing enough phase current for medium-power servo motors without triggering thermal limits. Command data enter the unit over the SERCOS fiber-optic ring, which supports deterministic cycle times and simplifies daisy-chain wiring between drives. Heat is removed by a built-in air blower, eliminating the need for external cabinet ventilation while maintaining component temperatures within the operating range. The housing carries IP10 protection, meaning solid objects larger than 50 mm cannot contact live parts while ventilation openings remain available for airflow. Reliable operation is permitted between +5 to +45 °C, so enclosure climate control must keep ambient air within that range during continuous service.

Above the standard range, the controller can run with linear current derating up to +55 °C, allowing short seasonal peaks without shutdown. Installation is permissible at elevations of up to 1000 m above sea level, where reduced air density is still adequate for the blower cooling profile. When the unit is stored or transported, it can withstand temperatures from -30 to +85 °C as long as it is kept dry. Electrical insulation meets Class C requirements under DIN VDE 0110, and the unit is part of line 03 and version 1.
