Advanced Performance Set-Up; N1: Hunting Prevention - YASKAWA V1000 Series Installation & Start-Up Manual

B.2 Parameter Table
<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 it
exceeds the value of L3-02, Stall Prevention Level. The drive decelerates after 100 ms and begins accelerating
again after restoring the current level.
<31> Use caution when working with regenerative loads as motor speed can exceed the frequency reference during
overvoltage suppression function operation. Set to "Disable" when motor speed needs to accurately match the
frequency reference, and also when using a braking resistor. An OV fault may still occur even when this function
is 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.

n1: Hunting Prevention

Use n1 parameters to configure hunting prevention operation.
If the motor vibrates while lightly loaded,
Hunting Prevention may reduce the vibration.
0: Disabled
1: Enabled
When quick response is needed disable
Hunting Prevention.
Sets the gain for the Hunting Prevention
Function.
If the motor vibrates while lightly loaded and
n1-01 = 1, increase the gain by 0.1 until
vibration ceases.
If the motor stalls while n1-01 = 1, decrease
the gain by 0.1 until the stalling ceases.
Sets the time constant used for hunting
prevention.
Sets the gain used for Hunting Prevention.
When set to 0, the gain n1-02 is used for
operation in reverse direction.
