Product Description:

The HDS03.2-W075N-HA13-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Designed for multi-axis automation, it works with a central motion processor to regulate servo or spindle motors by adjusting output current, voltage, and frequency in real time. In industrial systems, it converts high-level motion commands into regulated electrical power for coordinated positioning, speed control, and torque limiting in machinery such as machining centers and printing assemblies. This arrangement lets the controller respond quickly to changing load conditions while maintaining stable axis behavior during synchronized machine cycles. It is used where precise coordination between multiple axes is required for repeatable motion and controlled acceleration.

The controller is part of Line 03 and uses Version 2. As a member of the DIAX04 platform, it shares a common backplane bus and parameter structure with matching supply and auxiliary modules. The shared platform layout also keeps connector placement consistent with other modules in the same system. Motion references enter through an analog command interface, which accepts ±10 V speed or torque setpoints from a CNC or PLC. That input format suits systems that use conventional analog reference signals instead of a digital command channel. The power section can supply a continuous output of 75 A, giving the unit enough current capacity for demanding servo and spindle applications.

Cooling is handled by a built-in air blower that moves cabinet air across the finned power section and control electronics. The unit is classified as an HDS Drive Controller, and it is intended to operate with compatible modules in the same drive system. Clear space around the housing is still necessary so the blower can maintain unobstructed intake and exhaust airflow during sustained operation. This cooling method uses ambient cabinet air and does not require a separate external fan module.
