More than 100 years committed to technical progress has made us the leading manufacturer in the fields of variable AC drives, servo drives, control technology and robotics.
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.
Save energy with power regeneration
D1000 is open for various configurations. Usable in one-on-one or multiple unit connection the D1000 provides the flexibility needed to satisfy a broad range of energy efficient and low harmonics applications.
One-on-one system
Typical one-on-one applications like escalators, elevators, pumps or presses have one AC drive connected to a D1000.
Using the D1000 they take great benefit from:
- Energy cost reduction of complete installation
- Less space and heat by removed braking resistors
- Low input current harmonics
Multiple-unit connnection
Multiple unit systems like winders, transport systems, packaging systems or hoists with AC drives, servo systems or robots have an interconnected DC bus that is supplied by a single D1000. Energy is shared already in the DC bus, leading to reduced take up from the power grid.
In addition to the benefit of one-on-one systems such applications take advantages from:
- DC bus energy sharing
- Reduced space compared to multiple drives with built-in active frontend
- Single point of supply
For a wide range of applications
Using the D1000 regenerative converter unit saves energy and thereby money within a broad range of applications. This includes applications with large-inertia loads, 4-quadrant loads, long-term energy feedback and quick braking.
