Chapter 6 - Parameter Description [FU2]☞ Note: When the reference frequency is set inside the jumpfrequency, the output frequency goes to the frequencymarked by “n” symbol.☞ Note: If one frequency jump range is required, set allranges to the same range.FU2-19: Input/Output Phase Loss Protection (BitSet)FU2► Trip select19 001900Factory Default: 00 00FU2-17: Start Curve for S-Curve Accel/DecelPatternFU2-18: End Curve for S-Curve Accel/DecelPatternFU2► Start Curve17 40 %40Factory Default: 40% 40FU2► End Curve18 40 %171840This function is used to cut the inverter output off in caseof phase loss in either input power or inverter output.FU2-19 [Phase Loss Protection Select]Setting RangeFU2-192 nd bit 1 st bitDescription0 0 00 Phase loss protection does not work0 1 01 Protect inverter from output phase loss1 0 10 Protect inverter from input phase loss1 1 11Protect inverter from input and outputphase lossRelated Functions:FU2-22 to FU2-25 [Speed Search]Factory Default: 40% 40This parameter is used to adjust the Accel and Decelpattern when ‘S-Curve’ is selected in FU1-05 and FU1-06 respectively. To use this function, the ReferenceFrequency for Accel and Decel set in FU2-70 should beset to ‘Delta freq’.FU2-20: Power ON Start SelectionFU2►Power-on run20 --- No ---20Factory Default: No 00Output FrequencyMax. Freq./2If FUN-20 is set to ‘No’, restart the inverter by cycling theFX or RX terminal to CM terminal after power has beenrestored.If FUN-20 is set to ‘Yes’, the inverter will restart afterpower is restored. If the motor is rotating by inertia at thetime power is restored, the inverter may trip. To avoidthis trip, use ‘Speed Search’ function by setting FU2-22to ‘1xxx’.FU2-17 FU2-18 FU2-17 FU2-18LinearLinearTime[S-Curve Adjustment]Actual Accel Time = DRV-01 + (DRV-01 * FU2-17)/2 +(DRV-01*FU2-18)/2Actual Decel Time = DRV-02 + (DRV-02 * FU2-17)/2 +(DRV-02*FU2-18)/2Ex) If DRV-10: 1 sec, FU2-17: 40%, FU2-18: 20%,Actual Accel Time = 1 sec + (1sec*0.4)/2 + (1sec*0.2)/2= 1.3 sec101
