Product Description:

The HDS03.1-W100N-HA34-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It occupies one slot in a DIAX04 automation rack and converts line power into regulated DC for the associated servo amplifiers, enabling closed-loop speed, torque, and position control on multi-axis machines. By accepting differential analog speed commands and using an integral blower for heat removal, the unit provides dependable axis regulation without extensive external cooling hardware.

This controller belongs to the DIAX04 family and receives velocity or torque references through a dedicated ANALOG command interface, so motion cards or PLCs can modulate axis behavior with simple ±10 V signals. Thermal management relies on a Built-in Internal Air Blower; air is drawn across the heat sinks, keeping semiconductor temperatures within limits even under full electrical load. The power stage is rated for a continuous output of 100 A, which defines the maximum motor current the downstream amplifier can draw before the protective circuitry intervenes. Hardware identification places the device in Line 03, aligning it with matching supply and control modules that share the same mechanical keying and back-plane connections.

Hardware revision 1 is installed, meaning the board set and firmware socket correspond to the first production release and follow the initial diagnostic codes issued by Bosch Rexroth Indramat. The controller therefore fits directly into standardized DIAX04 racks where each axis channel demands the same current rating and cooling profile without requiring parameter adjustments across differing hardware variants.
