Product Description:

The HDS03.1-W100N-HA12-01-FW is a servo drive controller manufactured by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. It fits into DIAX04 modular racks and couples with supply units to energise multiple axes. Within production lines or machining centres, the module converts command signals into controlled drive currents, supervising motor speed and position so that automated equipment keeps cycle times and dimensional tolerances within specification while returning diagnostic data.

Most operational limits are set by its rated output of 100 A, allowing it to energise medium-power servo motors without saturation. Command data reach the controller through an ANALOG interface, which accepts ±10 V speed or torque references from a PLC or motion card. The unit belongs to the DIAX04 controller family, so parameter structure and firmware match the other drives in that rack. Thermal management relies on a built-in internal air blower; this fan pulls cabinet air through the heatsink so the module remains within permissible temperature rise at full current. Hardware “Line” code 03 identifies mechanical layout and connector position inside the housing.

Lifecycle attributes are fixed at version 1, and there are None alternative hardware variants for this order code, simplifying spare-part logistics. Service documentation and firmware files reference the original maker, Bosch Rexroth Indramat, and users can cross-match parameters across the entire HDS Drive Controllers portfolio when retrofitting or expanding an installation. These identifiers ensure that cabinet wiring, cooling airflow, and analog reference scaling remain identical from one implementation to the next, reducing commissioning time and limiting configuration errors.
