Compact inverters for demanding environments

The GA500 frequency inverter from Yaskawa works reliably even at an altitude of 4,000 m and at ambient temperatures of up to 60 °C.

The most important functions of the GA500 compact inverter from Yaskawa include an integrated EMC filter, the two-channel safety function STO with SIL3/PLe, the control of up to five inverters via a fieldbus card and intuitive setup and monitoring via smartphone apps. The inverters are designed so that they can be operated at altitudes of up to 4,000 m and in hot environments up to 60°C. The circuit boards are coated as standard and therefore protected against dust and moisture. The temperature-controlled cooling fans only run when required, minimizing soiling and extending maintenance intervals. An LED display and tactile keypad ensure simple and intuitive navigation through the menus.

According to the company, the embedded DriveWorksEZ programming environment makes it easy to implement specific processes and functions and allows external controllers to be dispensed with if necessary. The GA500 series devices can be programmed with a PC or smartphone via a USB connection, even when switched off and without a mains supply. The easily accessible power terminals allow mains and motor cables to be connected without having to remove the housing covers. Screwless terminals for the control cables also ensure reliable connections. The internal 24 V (DC) power supply provides an additional 150 mA for connecting external sensors in addition to supplying the I/Os. Due to the design of the frequency inverter, a motor of the next size up can also be operated with normal power for applications with variable torque.
