GA500 Frequency Microvariators set new performance standards, helping users simplify complex technologies by combining exceptional reliability, ease of use, power and adaptability. From the choice of dimmer, through design, installation, commissioning or troubleshooting, the specifications of the GA500 microvariator have been clearly focused on simplifying things. YASKAWA’s know-how is unmatched in product development that combines high technology and ease of use, and the latest result of this evolution is the new GA500. Compact and incredibly flexible in terms of connectivity, the GA500 is designed to work on virtually any application and can drive all types of motors from 0.2 to 30 kW.

Key features and benefits included: integrated EMC filters, integrated dual-channel security (STO SIL3/PLe), an optional fieldbus board to connect up to 5 sub-invertersnetwork, the ability to meet all global standards while meeting security standards, as well as simple configuration and monitoring, with applications for all mobile devices. There are also other features such as the robust design allowing the drives to operate up to 4000 m altitude and in hot environments up to 60ºC. In addition, tropicalized circuit boards protect against dust and moisture, while integrated temperature-controlled start-up fans only work when needed, so that any risk of contamination is minimized and the intervals between maintenance cycles can be extended.

The GA500’s bright LED display and touchscreen keyboard ensure easy and intuitive navigation, while the common menus and settings are organized and named as in all other YASKAWA dimmers, greatly reducing the need for further training.

In addition, the built-in programming environment for customizing the functions of the dimmer offers scalability and the ability to remove external controllers. The USB port allows easy connection to a PC or mobile device for programming, monitoring or troubleshooting, while the power terminals are easy to access and ensure a quick and convenient connection of the mains and motor cables without having to remove any protection on the inverter. Spring-loaded control terminals also allow reliable and durable connections without the need for resetting campaigns.

The internal 24 V DC power supply provides an additional 150 mA for use with external sensors, eliminating the addition of an external power supply. In addition, because the dimmer has an optimal normal load rate, this allows users to operate a larger engine in variable torque applications.

In conclusion, the GA500 microvariators, in addition to a compact and robust design, offer simple system integration, combining network support, application-based features and exceptional customization, fast installation and configuration, eliminating the need for additional peripherals, excellent machine performance thanks to the latest in-house motor control technology and safe and secure operation.
