No. Menu8 Start timeParameterInitial Value Setting Value00.2 12.0sExplanation of functionWhen setting the inverse characteristic "In", be aware that it operates in Coldcharacteristic from the starting of the motor until the current becomes lower than OCsetting, and then operates in Hot characteristic after that.The relay does not output within the time setting, so as to not operate when the motorstarts. When inverse characteristic "In" is set, it operates in Hot characteristic after Starttime.0.2 5.0s Set continuous overloading time of the overcurrent setting.9Over currentShock time1 30Select the operation characteristic when inverse characteristic "th", "In" are set. (Refer toThermal and inverse characteristic charts)1011Under currentthresholdUnder currentShock timeoFFSee the rightSet current value when detecting undercurrent.This cannot be set higher than the overcurrent value. Relay output for undercurrent is asfollows:Alarm ALo is set to "except uc": outputs at OC terminalAlarm ALo is set to "uc": outputs at AL/UC/TO terminals0.2 5.0s Set continuous under-loading time of under-current setting.12 Phase lossoFFonSet to "on" in the case that phase loss is detected.13Phase losstime0.5 5sSet operation time in the case that phase loss is detected.When phase loss detection is set to oFF, it does not display.1415ImbalancethresholdImbalancedurationoFF10 50%1 10sSet to 10~50% in case imbalance is detected.Imbalance ratio (%) = (Max.Current-Min.Current) ×100Max.CurrentSet operation time in the case that an imbalance is detected. When imbalance detectionis set to oFF, this does not display.16 Stall threshold17 Jam thresholdoFF2 8 timesoFF1.5 8 timesSet the ratio against overcurrent setting in the case of detecting the lock when starting.Setting range; Sc setting value ×OC 250A. This parameter is not displayed when thestart time is set to 0s.Set the ratio against overcurrent setting in the case of detecting the lock when running.Setting range; JA setting value ×OC 250A.18 Jam fault duration 0.2 5sSet the operating time in the case of detecting the lock when running. When lock JA is setto oFF, it does not display.19Analog OutputrangeSee the rightSet the current value as analog current output scale for 20mA output. Refer to page 87Current setting chart for setting range.oFFSet when disabling analog current output.noSet when disabling alarm output.AFSet when enabling alarm output. Refer to the table on page 89.20 AlertHtoucoFF50 100%Set to trigger an output when the running hour is set.Set in the case of detecting under-load.Set the ratio against the OC current when alarm outputting.88
