Product Description:

The HDD02.1-W040N-HA01-01-FW is a dual-axis drive controller manufactured by Bosch Rexroth Indramat for the HDD Drive Controllers series. Intended for installation in an enclosure, the module translates velocity, torque, or position references from a motion CPU into precisely regulated motor currents on two separate outputs. By combining control electronics, the power stage, and protective monitoring in a single housing, it streamlines cabinet layouts for automated printing presses, packaging equipment, and handling gantries. Internal diagnostics report operating status through the front display and fieldbus links so faults can be identified quickly.

An analog command interface accepts a differential reference range of DC ±10 V, allowing the drive to work with legacy PLC cards as well as modern motion controllers. The unit regulates 2 servo axes independently. At a 4 kHz current loop, it supplies a continuous 15 A per axis, while selecting the 8 kHz switching rate reduces the continuous channel capability to 10 A per axis. Short-term overloads are handled by a peak reserve of 40 A per axis, allowing rapid acceleration without tripping. The mechanical design meets the ventilation requirements of an IP10 enclosure, offering finger-safe protection while relying on forced cabinet airflow for heat removal.

Internal air cooling removes losses generated by the IGBT bridge, and at rated motor current the controller produces 95 W of heat on each channel, so unobstructed airflow is required. Logic circuits operate from a 24 V rail that provides 40 W of signal power for sensors, brake relays, and status LEDs. The drive maintains full performance up to 55 °C ambient temperature and installation heights of 1000 m without derating. Motor leads may extend to 75 m, allowing servo actuators to be placed across large production lines while keeping feedback quality within acceptable limits.
