Yaskawa - Model D1000 -Regenerative Converter Unit

The power regenerative converter unit
The D1000 regenerative converter unit complements the Yaskawa product range with a low harmonics Active Frontend Solution. Suitable for both regenerative individual drives and systems of AC drives, servo axis or robots, the D1000 feeds excess braking energy back into the power grid instead of dissipating it as heat.

Energy saving 4Q operation
D1000 saves energy by making excess braking energy available to other consumers in the same grid instead of wasting it as heat. By providing full braking power with 100 % duty cycle it allows for shorter machine cycles and can increase production efficiency.

Location independent machine performance
A controlled, boostable DC voltage guarantees the same level of DC voltage independent of the power supply voltage. Connected drives are always supplied with the same DC voltage, making machines invulnerable against locally different power supply conditions and assuring the same machine performance, no matter where it is used.

Clean power
The sinusodial input current with a total harmonic distortion of less than 5 % and a displacement power factor of ~1 minimize losses in grid components like generators and transformers. The higher power quality additionally reduces the potiential disturbance of other components.

Easy to handle package
D1000 comes in an easy to handle package. Only one material number for all components makes procurement simple and assures completeness and parts compatibility.

Cool operation
D1000 does away with braking choppers and resistors, thus saving valuable space and reducing the risk of fire. By not dissipating energy as heat the demand for ventilation is greatly reduced and maintenance, e.g. for resistor cleaning becomes needless.

Reduce costs
D1000 reduces the cost for energy and maintenance and quickly pays for itself.

Ready for global use
D1000 complies with major global standards such as UL, CE, RoHS and others.
