◆
n1: HUNTING PREVENTION
The Hunting Prevention function will not let low inertia or operation with a light load cause hunting. Hunting
frequently occurs when you have a high carrier frequency and an output frequency less than 30 Hz.

HuntPrev Selection
Sets the function to prevent hunting.
0
( 0 to 2 )
Note:
When you replace a V1000-series drive with a Q2V drive, set
n1-01 = 1 [HuntPrev Selection = Enabled]
.
When drive response is more important than the decrease of motor vibration, disable this function.
0 : Disabled
1 : Enabled
2 : Enabled (High Carrier)

HuntPrev Gain Setting
Sets the performance of the hunting prevention function. Usually it is not necessary to change this
parameter.
1.00
(0.00 - 2.50)
Adjust this parameter in these conditions:
•
When
n1-01 = 1, 2 [HuntPrev Selection = Enabled, Enabled (High Carrier)]
, if oscillation occurs when you
operate a motor with a light load, increase the setting value in 0.1-unit increments.
•
When
n1-01 = 1, 2
, if the motor stalls, decrease the setting value in 0.1-unit increments.

HuntPrev Time Constant
Sets the primary delay time constant of the hunting prevention function. Usually it is not
necessary to change this parameter.
Determined by o2-04
(0 - 500 ms)
Adjust this parameter in these conditions:
•
Load inertia is large: Increase the setting value. If the setting value is too high, response will be slower. Also,
there will be oscillation when the frequency is low.
•
Oscillation occurs at low frequencies: Decrease the setting value.

HuntPrev Gain Reverse
Mode
Sets the performance of the hunting prevention function. This parameter adjusts Reverse run.
Usually it is not necessary to change this parameter.
0.00
(0.00 - 2.50)
Note:
When you set
n1-05 = 0
, the value set in
n1-02 [HuntPrev Gain Setting]
is effective when the motor rotates in reverse.
