Yaskawa frequency inverters U1000 compact series

Yaskawa U1000 series – The Drive for Maximum Efficiency

The U1000 is a highly efficient inverter drive based on latest Matrix converter technology. With full power regeneration capability it offers great energy saving potential while sinusoidal input currents and a power factor close to one reduce stress on grid components like transformers and power lines. With an ultra-compact shape the U1000 is the first choice for innovative, energy-efficient drive solutions with or without power regeneration.

- Innovative matrix technology
The U1000 comes without a DC bus and provides highly efficient direct conversion of power from AC to AC up to a maximum output frequency of 400Hz. With this and the capability to run induction as well as permanent magnet motors with and without encoder feedback U1000 is the perfect match for a variety of applications and machinery.

- Energy saving 4Q operation
Thanks to Matrix technology U1000 can operate fully regenerative, means braking energy is fed back to the grid an made available for other consumers. By that not only energy cost are reduced but also braking resistors and their cooling become obsolete and the risk of fire is reduced.

- Functional safety built in
U1000 has a SIL3 STO function built in and so offers a simple solution for improving machine safety.

- Reduce costs
In addition to a reduction of energy consumption U1000 provides cost saving benefits by a simplified installation, smaller space requirements and smaller panels, less cooling requirement and less need for maintenance.

- 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. This, at the same time, greatly reduces the potential of disturbance of other devices and improves the reliability of a machine or installation.

- Time saving installation
As no external components are required, connecting a U1000 drive becomes a matter of minutes. 3 wires in, 3 wires out, done. It cannot be easier to build up a low harmonic regenerative solution.

- Up to 50% smaller
U1000 does not need any external components like AC chokes or harmonic filters. Even an EMC filter is built in.* Nevertheless the required installation space is up to 50% smaller than other regenerative or low-harmonic drive solutions.

Power Renegeration to Maximize Efficiency

Rising energy cost and polluted power supply systems continuously drive the need for low harmonics and power regeneration. The U1000 offers both without the complexity of traditional solutions. On first sight it looks like a new Inverter Drive. But it contains all you need to get a system architecture with maximum efficiency at a minimum footprint.

Yaskawa frequency inverter U1000 series has a built In Power Regeneration

The U1000 has power regeneration built in. Braking energy that is typically wasted in resistors can be used by other consumers in the same grid, saving energy and cost.
- Saves energy 
- Less heat generation, reduced need for ventilation
- Greatly reduced risk of fire 
- Less maintenance 
- Less parts

Yaskawa frequency inverter U1000 series is Compact and Easy

The all-integrated design of the U1000 reduces the required installation space for more than 50%. Traditional regenerative and low harmonic solutions often use external transformers, reactors, and filter circuits. Not so the U1000. EMC and current filter components are built in and external components are not neccessary.

The U1000 needs only a minumum of space and is easily installed in shortest time. 
- Smaller panels 
- Less components to handle 
- Simple installation in short time 
- Perfectly fits in existing installations - easy retro fit

Clean Power

With the U1000, typical field problems caused by current harmonics, such as excessive heating of power grid devices or malfunction of peripheral electronics, are history. The U1000 matrix converter provides clean power with a total harmonic current distortion of less than 5%. 
- No over-dimensioning of transformers, generators or cables 
- Less watt loss on power grid components 
- Sinusoidal input current with cosɸ ~0.98 
- Easy installation by all-integrated design 
- Reduced lifecycle cost

The Yaskawa drive U1000 series has a built in bypass function

Whenever an application is running at the frequency and voltage of the power grid, U1000 can stop modulating the output and switch the motor directly to the grid.

- No external components needed 
- Minimum watt loss on drive 
- Silent motor operation

Smaller Transformers and Generators

The U1000 provides a power factor close to One. By that it reduces losses in generators, transformers and cables, allowing a size down of these components for new installations or the possibility to add more drives to an existing installation without increasing transformer power.

Yaskawa vfd U1000 series comes with a built in functional safety

The U1000 comes with a built in dual-channel safe torque off (STO) function that meets the requirements of SIL3/Ple and offers an easy way to improve machine safety without the need for complex external wiring.

- Simple wiring 
- Less components and higher reliability
