Thecurvemakes itpossible toestablishmaximumworktime(T)accordingtousefrequency(F).WithreferencetoIEC34-1Standard,the740gearmotorwithanS3duty,canope-rateatausefrequencyof100%.Toensureefficientoperation,itisneces-sarytooperateintheworkrangebelowthecurve.

Important: The curve is obtained at atemperature of 20°C. Exposure tothedirect sun rayscan reduceusefrequencydownto20%.

CalculationofusefrequencyUse frequency is the percentage ofeffectiveworktime(opening+closing)comparedtototaltimeofcycle(opening+closing+pausetimes).Calculationformula:

Ta+Tc %F= X100 Ta+Tc+Tp+Tiwhere: Ta=openingtimeTc=closingtimeTp=pausetimeTi=timeofintervalbetweentwocompletecycles
