Product Description:

The HDD02.2-W040N-HD32-01-FWA is an AC drive controller produced by Bosch Rexroth Indramat within the HDD Drive Controllers series. It converts regulated DC-bus energy into controlled three-phase outputs that drive servo motors, maintaining closed-loop velocity and position for automated machinery. Acting as the link between motion feedback and machine sequencing, it delivers the programmable current and voltage necessary for synchronized manufacturing tasks.

Electronically, the unit handles 2 axes, and each axis is commanded through the SERCOS interface for deterministic fiber-optic communication. Continuous output reaches 15 A per axis at a 4 kHz current loop, or 10 A when the switching frequency is raised to 8 kHz. Acceleration events permit surges to 40 A per axis, while the DC link operates safely between 530 V and 670 V to support a maximum phase-to-phase voltage of 500 V and output frequencies up to 1000 Hz. The controller draws 25 A of continuous input current and is rated for 40 A on the line side. Internally, it allocates 45 W for control supply power and 40 W at ±26 V for signal processing, ensuring that the 1 Vpp sinusoidal encoder inputs on each axis are digitized without distortion. Power loss at continuous current is 110 W per channel, and this heat is managed by the integrated cooling system.

A built-in air blower moves cooling air through the heat sink, and the housing dissipates losses while remaining within protection class IP10. The drive occupies a 50 mm width, 308 mm depth, and 498 mm height and weighs 7 kg, which supports dense cabinet layouts. Nominal performance is maintained up to 45 °C ambient, while reduced-load operation is allowed to 55 °C or to elevations of 1000 m above sea level. A short-circuit current rating of 42 kA RMS and a maximum installation bus voltage of 670 V set the protective limits for upstream fusing and cabinet design.
