HDS03.1-W100N-HA18-01-FW Bosch Rexroth Indramat

Product Description:

The HDS03.1-W100N-HA18-01-FW is a digital drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. In a multi-axis DIAX04 rack, this module supplies regulated power and closed-loop control to synchronous and induction servomotors used in machine tools, handling systems, and assembly cells. By converting high-voltage DC from a shared supply into precisely modulated phase currents, the unit becomes a core element of coordinated industrial automation.

Its command interface is ANALOG, so the axis receives speed or torque references as ±10 V signals that can be generated by motion cards or PLC outputs. Membership in the DIAX04 controller family allows parameter compatibility and firmware loading with other DIAX04 devices, reducing commissioning time. Cooling is handled by a Built-in Internal Air Blower; this integral fan draws air through the heatsink, maintaining semiconductor temperatures without external ducting. The drive can deliver a continuous output of 100 A, enabling it to run medium-frame motors at their nominal torque while still retaining overload headroom. It is classified under Line 03, identifying the mechanical layout, connector orientation, and diagnostic LED scheme common to this hardware generation.

The hardware is released as Version 1, which establishes the baseline for service parts and firmware compatibility across subsequent revisions. Because it is manufactured by Bosch Rexroth Indramat, replacement components such as power sections, fan trays, and encoder cables follow the same part numbering convention found throughout the company’s automation catalog. Within the HDS Drive Controllers series the sizing envelope permits direct rack mounting beside identical units, aiding thermal balancing. The designation HDS Drive Controller also confirms that no separate amplifier is required.
