Product Description:

The HDS03.1-W100N-HA07-01-FW is a drive controller distributed by Bosch Rexroth Indramat under the HDS Drive Controllers series. Designed for integration inside DIAX04 multi-axis racks, the module functions as a regulated power stage that links motion processors to servo and spindle motors. Within an automated system it converts low-level velocity, torque, or position references into proportionate motor current, so it forms the electrical bridge between the CNC or PLC and the electromechanical load. This capability makes the unit suitable for machine tools, packaging lines, and handling equipment where precise axis regulation is mandatory.

The controller delivers a continuous output of 100 A, which defines the peak motor current the module can regulate without thermal derating. Command data reach the unit through an ANALOG channel, so velocity or torque references are transmitted as ±10 V or 0…20 mA signals instead of digital fieldbus words. Membership in the DIAX04 automation family ensures mechanical compatibility with shared backplane power supplies and diagnostic tools. Heat generated by the power electronics is removed through a built-in internal air blower, eliminating the need for cabinet fans and keeping component temperature within limits. Finally, its placement in Line 03 indicates the hardware design revision that pairs with matching firmware and option cards.

Firmware markings identify the unit as version 1, meaning the hardware is paired with the initial feature set for its release cycle, and the catalog lists no alternate versions, simplifying spare-part selection. Engineers link the amplifier to external motion cards through the dedicated command interface, so tuning resistors or scaling parameters must match the referenced signal range. Air pulled through the slots travels along an internal cooling path that directs flow across the IGBT modules before exiting the top of the housing, sustaining stable operation during high-duty positioning sequences.
