B.2 Parameter Table396 YASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07)◆ n: Advanced Performance Set UpThe n parameters are used to adjust more advanced performance characteristicssuch as hunting prevention, speed feedback detection, high-slip braking and R1online tuning.<1> Default setting value is dependent on parameter A1-02, Control Method Selection. The value shown is forA1-02 = 2-OLV control.<2> Default setting value is dependent on parameter A1-02, Control Method Selection. The value shown is forA1-02 = 0-V/f Control.<7> Default setting value is dependent on parameters C6-01, Drive Duty Selection, and L8-38, Carrier FrequencyReduction.<9> Default setting value is dependent on parameter E1-01, Input Voltage Setting.<12> Default setting value is dependent on parameter o2-04, Drive/kVA Selection.<14> Default setting value is dependent on parameter o2-09, Initialization Spec. Selection.<15> Default setting value is dependent on parameter A1-02, Control Method Selection. The value shown is forA1-02 = 5-PM OLV Control.<24> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.<29> Setting value 2 is not available A1-02 = 5-PM OLV Control. When enabled, the drive stops accelerating when itexceeds the value of L3-02, Stall Prevention Level. The drive decelerates after 100 ms and begins acceleratingagain after restoring the current level.<31> Use caution when working with regenerative loads as motor speed can exceed the frequency reference duringovervoltage suppression function operation. Set to "Disable" when motor speed needs to accurately match thefrequency reference, and also when using a braking resistor. An OV fault may still occur even when this functionis enabled if there is a sudden increase in the regenerative load.No. Name Description Range Def.ControlModeAddr.HexPg.V/fOLVPMn1: Hunting PreventionUse n1 parameters to configure hunting prevention operation.n1-01 Hunting PreventionSelectionIf the motor vibrates while lightly loaded,Hunting Prevention may reduce the vibration.0: Disabled1: EnabledUsed in V/f Control only.When quick response is needed disableHunting Prevention.0,1 1 A − − 580 —
