U1000 - Low Harmonics Regenerative Matrix Converter


Do You Have Problems with AC Drives?
Yaskawa's development of the world's first application of matrix converter technology in 2006 made it possible to solve AC drive problems. Further evolution of this technology has resulted in the U1000.
This sophisticated series of motor drives available only from Yaskawa eliminates the problems of standard AC drives.
The U1000 tops the performance of general-purpose AC drives to further improve the performance of your facilities.


Regenerative Energy

When a motor rotates, it consumes energy. When a motor is rotated, it generates energy.
You can save energy by using regenerative energy instead of wasting it.


Efficient Energy Usage

Braking resistor results in discarding energy as heat,but you can return this regenerative energy to the power supply to save energy.


You Can Save This Much!

Example of the Effectiveness of Regenerative Energy Savings


Visualizing Savings in Electricity

Use analog outputs or communications networks to monitor all sorts of data with easy operations. You'll instantly see the energy that you've saved.


Without peripheral devices, the input current waveform becomes sinusoidal, similar to that of a commercial power supply, so the harmonic pollution of the power supply is minimized for the protection of surrounding machinery. The available power system capacity can be increased, and the regulations on harmonics easily met.

When an AC drive converts power, the input current is distorted, which results in harmonics.
These harmonics can interfere with other electric devices, such as by causing overheating or damage to power supply facilities and malfunction and noise in precision devices.


Reduce Power Supply Capacity

The power factor is high, so you can use a lower power supply capacity.
You can also downsize wires and generator capacity, and may qualify for price benefits from your power company.

Harmonic countermeasures not necessary

Harmonic countermeasures that were previously required to connect a converter, such as input AC reactors, harmonic filter reactors, and capacitors, are not necessary, which helps you save wiring, space, and energy costs.

Drives Synchronous Motors

When a motor rotates, it consumes energy. When a motor is rotated, it generates energy. You can save energy by using regenerative energy instead of wasting it.

All types of motors can be controlled, including induction motors and IPM/SPM synchronous motors, without using sensors.


Wide Product Lineup

We've increased the number of 200-V-class models from 4 to 10 and the number of 400-V-class models from 7 to 23.


Improved Power Factor

The high power factor allows you to reduce the power supply capacity.


Compliance with SIL3 Safety Standard

SIL3 compliance eliminates the need for magnetic contactors (MCs).


High-speed Operation!

Output frequencies are supported up to 400 Hz.


Solve Noise Problems!

Models are available with built-in EMC noise filters to reduce noise generated by AC drives.∗

∗ Be sure to use a stand-alone EMC filter for models 

   CIMR-U*4*0477 to 4*0930.


Commercial Power Switching

Switching to and from commercial power is possible without phase detectors, contactors, and other such peripheral devices.
Note   V/f control without a PG must be used.


Maintenance Even during Power Interruptions!

A built-in 24-V power supply unit lets you check parameters even when the main circuit power supply is OFF.


Precise Operation!

A speed response of 250 Hz∗ enables rapid following of AC drive frequency references.

∗ Closed-loop vector control, Closed-loop vector control for PM


Cutting-Edge Torque Characteristics

•    Powerful torque at 0 Hz even without the use of a motor encoder.
Powerful torque at 0 Hz even without the use of a motor encoder. Achieve even more powerful starting torque at zero speed with an IPM motor.
∗   No speed sensors or pole sensors required.

∗1   Achieving this torque output requires a larger capacity models.
∗2   Contact your Yaskawa or nearest agent when using PM motors except SSR1 series or SST4 series motors manufactured by Yaskawa Motor Co., Ltd

•    High-performance current vector control achieves powerful starting torque with an induction motor.


Environmental Features

•    Protective Design
A variety of protective designs are available to reinforce the drive against moisture, dust, oil mist, vibration, corrosive sulfur gas, conductive particles, and other harsh environments.
•    RoHS
All standard products are fully compliant with the EU’s RoHS directive.


Models with built-in EMC filters are available

Be sure to use a stand-alone EMC filter for models
CIMR-U*4*0477 to 4*0930.


Models with built-in 24-V power supply units are available




•    Safety Regulations
The products comply with ISO/EN13849-1 Cat.3 Ple and IEC/EN61508 SIL3 (two safety inputs and one EDM output).
An External Device Monitor (EDM) function has also been added to monitor the safety status of the drive.
Compliance with SIL3 decreases the malfunction rates and creates a safety system.
When compliant with EN81, the number of required magnetic contactors, which has conventionally been two, can be reduced using the safety function.
