GA500 Drive is a general-purpose drive for industrial use. Applications range from simple motor control of pumps or fans up to more demanding compressors, transport
systems, positioning tasks etc. Key attributes are ease of use, flexibility and sustainability. Loaded with valuable features and functions GA500 drives greatly simplifies system designs and maximize system and machine performance while reducing the effort for installation and setup to a minimum.
GA500 drives must be selected according to power supply voltage, motor rated current, load profile of the application, and ambient condition of the area they are operated in. GA500 drives offer two separate performance ratings: Heavy Duty and Normal Duty. In Heavy Duty the GA500 can run applications with constant torque and heavy overload of up to 150% for 1 minute, such as hoist, conveyors, presses, certain types of compressors, etc. Normal Duty is intended to drive applications with variable torque characteristics and low overload demand of not more than 110% for 1 minute, such as fans, blowers, pumps, etc. Normal Duty allows the drive to operate a one size larger motor than in Heavy Duty rating. GA500 drives are designed to be wall mounted upright and in clean environmental condition. In case of special mounting methods (heatsink external, horizontal, etc.), high ambient temperature (>50 C), high altitude (above 1000 m), use of high carrier frequency, and so forth, an output current derating must be considered when selecting the drive. Finless drives must be mounted on an external heatsink or cooler. The selection of a heatsink is described in
