SIEPCYEUOQ2V01A Q2V Technical Manual
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.

DCBus Stab.Control
Sets the oscillation suppression function for the DC bus voltage.
0
(0, 1)
0 : Disabled
1 : Enabled
Note:
If the DC bus voltage does not become stable with light loads and the drive detects
ov [Overvoltage]
, set this parameter to 1.

DCBus Stab Time
Adjusts the responsiveness of the oscillation suppression function for the DC bus voltage. Set
n1-
13 = 1 [DCBus Stab.Control = Enabled]
to enable this parameter.
100.0 ms
(50.0 - 500.0 ms)
Note:
Adjust this parameter in 100 ms increments.
◆
n2: AFR - AUTO FREQ REGULATION
The speed feedback detection reduction function (or AFR: Automatic Frequency Regulator) helps the speed
become stable when you suddenly apply or remove a load.
Note:
Before you change
n2-xx parameters
, do one of these procedures:
•
Set the motor parameters and V/f pattern correctly.
•
Do Rotational Auto-Tuning.
■
n2-01: AFR Gain
No.
(Hex.)
Name
Description
Default
(Range)
n2-01
(0584)
AFR Gain
Sets the gain of the AFR function as a magnification value. Usually it is not necessary to change
this setting.
1.00
(0.00 - 10.00)
Adjust this parameter in these conditions:
•
If hunting or oscillation occurs with light loads, increase the setting value in 0.05-unit increments and examine
the response.
•
When torque is not sufficient with heavy loads or to make the torque or speed response better, decrease the
setting value in 0.05-unit increments and examine the response.
■
n2-02: AFR Time 1
No.
(Hex.)
Name
Description
Default
(Range)
n2-02
(0585)
AFR Time 1
Sets the time constant that sets the rate of change for the AFR function. Usually it is not necessary
to change this setting.
50 ms
(0 - 2000 ms)
Adjust this parameter in these conditions:
•
If there is hunting or oscillation with a light load, increase the setting value in 50 ms increments and examine
the response. If the load inertia is large, increase the setting value in 50 ms increments and examine the
response.
