Refer to parameter descriptions formore detail.Warning alarm outputs and displays the trip message whenovercurrent above the threshold value keeps on.Set the output current level at which the output freq will beadjusted to prevent the motor from stoping due to overcurrentetc. it activates during accel/ constant speed/ decelto prevent the motor stall.Parameter Name Code DescriptionAccel/Decel patternStopping methodStarting DC InjectionBraking Voltage/ TimeFrequency Limit selectionDynamic brakingFU1-05FU1-06FU1-07FU1-12FU1-13FU1-23FU1-24FU1-25FU2-75FU2-765 types of Accel/ Decel pattern: ‘Linear’, ‘S-curve’, ’Ucurve’,’Minimum’, ‘Optimum’ settable according toappplication and load characteristic. If ‘S-curve’ is selected,the desired value of [FU2-17], [FU2-18] is settable.3 types of stopping method ‘Decel’, ‘DC-brake’, ‘Free-run’selectable. If ‘DC-brake’ is selected, the desired value of[FU1-8]~ [FU1-11] is settable.The motor accelerates after the preset [FU1-12] for thepreset [FU1-13] is applied. Starting DC injection braking isinactive when the value is set to 0 in control mode otherthan V/F and Slip compensation.Limits the active frequency. Inverter operates at the freqrange between upper freq limit [FU1-25] and bottom freqlimit [FU1-24] and higher/ lower freq value is entered, it isautomatically replaced by limit value. Setting range: [FU1-20] Maximum freq to [FU1-21] Base freq.Select the DB resistor mode when the regenerative load. Isconnected. Refer to DBU manual for more details.43
