Yaskawa GA700 Inverter

Performance that is superior to the A1000 and with many exciting new features.

Improved motor control and improved (up to 6%) efficiency.

Available ratings, 0.55 to 630kW in 400v series. We are taking orders now for inverters up to 132kW. Inverters from 160kW to 315kW will be available from February 2017 and the largest inverers will be released at the end of 2017.

The GA700 is also available in three phase 200v input, ratings from 0.55 to 110kW.

Reduced panel space required. Drives can be mounted side by side without gap and up to 75kW can be mounted horizontally. Reduced size compared to A1000, up to 50% on some models. EMC filters are built –in, braking transistors built-in up to 75kW, DC reactors built-in over 22kW. Included features such as SIL3 STO and DriveWorks EZ can also reduce component count.

All major networks supported, EtherNet/IP, Modbus, EtherCAT, Ethernet Powerlink, ProfiNet, ProfiBus, CAN Open, DeviceNet, CC-Link, Mechatrolink and Memobus. Up to 5 drives can be controlled through one network option card.

What is an “inverter”?

AC Inverters are devices for controlling motor speed by converting a DC voltage generated from your connected power supply to a varying frequency AC voltage which can control the speed of the connected motor. The development of semiconductor technology and the processing power of modern microprocessors have enhanced AC inverter drive performance significantly. When applied to industrial and environmental applications, they have improved productivity, reduced energy needs and made a huge contribution to the development of the motor control industry. They  have also brought about a substantial change to our lives. For example, airflow from air-conditioners, speed of elevators, pumps and fans can all be regulated by changing motor speed.  By regulating the speed, energy consumption is reduced which contributes to energy conservation.

Not sure that it is an Inverter you need? Inverters are called by different names and so it can be confusing, but essentially if you are looking for electronics to control the speed of an AC motor then it is likely that you are looking for an Inverter which can also be known as a Variable Frequency Drive (VFD), Variable Speed Drive (VSD), AC Drive, AC inverter drive, Frequency Converter or AC motor speed controller.
