53POWER LOSS START MODE (Parameter P48)CAUTION:Depending on the start mode function setting, if the run signal is ON and the power is turnedON or the power is restored after a power failure, the unit may start (restart) suddenly.(Design the machine so that personal safety can be ensured even if the unit starts suddenly.)Failure to do so could lead to injury.Depending on the start mode function setting, if the fault trip is reset with the run signalpresent, the unit may restart suddenly.(Reset the trip after ensuring personal safety.)Failure to do so could lead to injury.This parameter sets the starting operation for when an externally set run signal is input whenthe power is turned ON.∗ The factory setting is "1" (OP stop).∗ When set to "0" : Operation starts immediately when the power is turned ON.∗ When set to "2" : Operation starts after the wait time has elapsed after the power isturned ON.Data settingvalueOutlineoperation Details of operation0 Run Operation starts immediately when the power is turned ON and the lowvoltage level (LU level) is exceeded.1 "OP" stopThe inverter OP trips when the power is turned ON and the low voltagelevel (LU level) is exceeded.Turn the start input signal OFF once, reset the inverter and then turn therun signal ON again to resume operation.2 Operate afterwait timeThe inverter starts when the power is turned ON, the low voltage level(LU level) is exceeded and the wait time is passed.(The wait time is set with parameter P50.)3 "OP" stopThe inverter OP trips when the power is turned ON and the low voltagelevel (LU level) is exceeded.Turn the run signal OFF once, reset the inverter and then turn the runsignal ON again to resume operation.(This setting will function in the same manner as data "1" if the runsignal is ON when the power is turned ON. However, starting after thewait time has elapsed is possible during normal startup.)
