E6582175Q-14172) Motor 150%-overload detection time f607f607f607f607Parameter f607 is used to set the time elapsed before the motor trips under a load of 150% (overload trip 2)within a range of 10 to 2400 seconds.3) Inverter overload detection method f631f631f631f631As this function is set to protect the inverter unit, this function cannot be turned off by parameter setting.The inverter overload detection method can be selected using parameter f631 (Inverter overload detection method).If the inverter overload trip function (ol1) is activated frequently, this can be improved by adjusting the stall operationlevel f601 downward or increasing the acceleration time acc or deceleration time dec. = (150%-60s)Protection is given uniformly regardless of temperature by the 150%-60 sec overload curve. = (Temperature estimation)This parameter adjusts automatically overload protection, predicting the inverter internal temperature rise.4) Electronic thermal memory f632f632f632f632When the power is OFF, it is possible to reset or maintain the overload totaling level.This parameter's settings are applied both to the motor's electronic thermal memory and the electronic thermal memoryfor inverter protection.5) Overload alarm level f657f657f657f657When the motor overload level reaches to f657 setting value (%) of overload trip (ol2) level, “l” will be displayedon the left side digit and the “l” and output frequency monitor will be blinking alternately on overload alarm status.Overload alarm signal can be output from output terminal.
