Product Description:

The HDD02.2-W040N-HD01-01-FW is a dual-axis drive controller manufactured by Bosch Rexroth Indramat in the HDD Drive Controllers series. It regulates and safeguards two servo axes by coordinating current loops and motion commands between the power stage and plant control. Within automated packaging, printing, or material-handling cells, the unit supplies controlled three-phase power to matched motors while exchanging status data with supervisory control hardware. Its dual-axis layout is useful where paired motions must stay synchronized during repetitive production cycles.

The controller manages 2 independent motor channels, and position data arrives over the SERCOS fiber-optic interface so axis timing remains deterministic across the drive ring. At a switching frequency of 4 kHz, the unit can supply a continuous current of 15 A per axis. Increasing the switching frequency to 8 kHz lowers that capability to 10 A per axis because of additional switching loss. During rapid acceleration cycles, it tolerates transient surges up to 40 A per axis, permitting high dynamic torque before thermal protection intervenes. Sustained operation at these load points creates roughly 110 W per axis of internal power dissipation that must be removed by cabinet airflow or heat sinks. This operating profile suits applications that alternate between steady running and short bursts of acceleration.

The electronics have an enclosure rating of IP10, so the unit requires installation inside a filtered control cabinet that limits dust exposure while still allowing convection. The housing therefore depends on the surrounding enclosure for protection against contact and contamination. Continuous duty is supported at ambient temperatures up to +55 °C with derating, making ducted cooling advisable when several drives share the same cabinet space. Approved mounting is limited to elevations of 1000 m above sea level. Beyond this height, reduced air density impairs heat exchange and requires proportional reductions in permissible current output.
