The Yaskawa D1000 regenerative converter unit saves energy and space. Suitable for both regenerative individual drives and systems of AC drives, servo axes or robots, the D1000 feeds excess braking energy back into the grid instead of converting it into heat. This not only reduces energy consumption and cost but also contributes to the protection of our environment.
- Low energy consumption due to common DC bus systems – the braking energy of one drive is consumed by other drives in the system
- Sinusoidal input current reduces the strain on the power supply system (lines, transformers)
- Less installation space as braking transistors and resistors are not required
- Lowers the total operating costs of the system
Energy efficient four-quadrant
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 sinusoidal 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 potential disturbance of other components.
- Sinusoidal input current reduces the strain on the power supply system (lines, transformers)
- Less installation space as braking transistors and resistors are not required
- Lowers the total operating costs of the system
Multiple-unit connnection
Multiple unit systems like winders, transport systems, packaging systems or hoists with inverter 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
