B.2 Parameter Table362 YASKAWA ELECTRIC TOEP C710606 09B YASKAWA AC Drive V1000 Installation & Start-Up Manual◆ n: Advanced Performance Set-UpThe n parameters are used to adjust more advanced performance characteristics such ashunting prevention, speed feedback detection, high-slip braking and R1 tuning.<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 for A1-02= 5-PM OLV Control.<24> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.<25> Parameter setting value is not reset to the default value during drive initialization, A1-03 = 1110, 2220, 3330.<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.<50> The setting range depends on the control mode set in A1-02. For PM OLV Control the setting range is 0 to 2.<51> Parameter value is changed if E2-11 is manually changed or changed by Auto-Tuning.<56> The default value is 0 for all 200 V Single-Phase drives.<57> Default setting value is dependent on parameter o2-04, Drive/kVA Selection and C6-01, Drive Duty Selection.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: EnabledWhen quick response is needed disableHunting Prevention.0,1 1 A − − 580 —n1-02 Hunting PreventionGain SettingSets the gain for the Hunting PreventionFunction.If the motor vibrates while lightly loaded andn1-01 = 1, increase the gain by 0.1 untilvibration ceases.If the motor stalls while n1-01 = 1, decreasethe gain by 0.1 until the stalling ceases.0.00 to2.50 1.00 A − − 581 —n1-03 Hunting PreventionTime ConstantSets the time constant used for huntingprevention. 0 to 500 <12> A − − 582 —n1-05 Hunting PreventionGain while in ReverseSets the gain used for Hunting Prevention.When set to 0, the gain n1-02 is used foroperation in reverse direction.0.00 to2.50 0.00 A − − 530 —
