Possible Solutions
Default
Recommended
Setting
•
Unsatisfactory motor torque and speed
response
•
Hunting or oscillation at mid-range
speeds (10 Hz to 40 Hz)
n2-01 [AFR Gain]
•
To increase the speed of torque or speed response, decrease
the setting value in increments of 0.05.
•
If hunting or oscillation occur, decrease the setting value in
increments of 0.05.
1.00
0.50 - 2.00
n2-02 [AFR Time 1]
•
To increase the speed of torque or speed response, decrease
the setting value in increments of 10 ms and examine the
response.
•
If hunting or oscillation occur or if the load inertia is too
much, increase the setting value in increments of 50 ms and
examine the response.
Note:
Make sure that this parameter setting is:
n2-02 ≤ n2-03 [AFR
Time 2]
holds true.
When you adjust
n2-02
, you must also increase the
C4-02
[Trq Comp Delay Time]
value by the same ratio.
50 ms
50 ms to 2000 ms
ov [overvoltage]
occurs when the drive
stops accelerating, starts to decelerate, or
when there are large changes in the load.
n2-03 [AFR Time 2]
•
If
ov
occurs, increase the setting value in increments of 50 ms
and examine the response.
•
If the response is not sufficient, decrease the setting value in
increments of 10 ms and examine the response.
Note:
Make sure that this parameter setting is:
n2-02 [AFR Time 1]
≤ n2-03
. When you adjust
n2-03
, you must also increase the
C4-06 [M2 Trq Comp Delay Time]
value by the same ratio.
750 ms
750 ms to 2000 ms
C4-06 [M2 Trq
Comp Delay Time]
•
If
ov
occurs, increase the setting value in increments of 10 ms
and examine the response.
•
If the response is not sufficient, decrease the setting value in
increments of 2 ms and examine the response.
Note:
Make sure that this parameter setting is:
C4-02 [Trq Comp
Delay Time] ≤ C4-06
.
When you adjust
C4-06
, you must also increase the
n2-03
[AFR Time 2]
value by the same ratio.
150 ms
150 ms to 750 ms
•
Unsatisfactory motor torque and speed
response
•
Hunting or oscillation
C4-02 [Trq Comp
Delay Time]
•
If torque or speed response are slow, decrease the setting
value in increments of 2 ms.
•
If hunting or oscillation occur, increase the setting value in
increments of 10 ms.
Note:
Make sure that this parameter setting is:
C4-02 ≤ C4-06 [M2
Trq Comp Delay Time]
.
When you adjust
C4-02
, you must also increase the
n2-02
[AFR Time 1]
value by the same ratio.
20 ms
20 ms - 100 ms
•
Speed response is slow.
•
Speed is not stable.
C3-02 [Slip Comp
Delay Time]
•
If speed response is slow, decrease the setting value in
increments of 10 ms.
•
If speed is not stable, increase the value in increments of 10
ms.
200 ms
100 ms to 500 ms
Speed precision is unsatisfactory.
C3-01 [Slip Comp
Gain]
•
If speed is too slow, increase the setting value in increments of
0.1.
•
If speed is too fast, decrease the setting value in increments of
0.1.
1.0
0.5 - 1.5
•
The volume of the motor excitation
sound is too high.
•
Hunting or oscillation at low speeds (10
Hz or lower)
C6-02 [Carrier
Frequency
Selection]
•
If the volume of the motor excitation sound is too high,
increase the carrier frequency.
•
If hunting or oscillation occur at low speeds, decrease the
carrier frequency.
7(Swing PWM1)
0 to upper limit
value
•
Torque at low speeds (10 Hz or lower)
is not sufficient. speed response is slow.
•
Speed response is slow.
•
Large initial vibration at start up.
•
E1-08 [Mid A
Voltage]
•
E1-10 [Min
Output Voltage]
•
If torque or speed response are slow, increase the setting
value.
•
If there is large initial vibration at start up, decrease the setting
value
Note:
If you set the value too high, the drive can output a large
torque reference although the load is light.
•
E1-08: 12.0 V
•
E1-10: 2.5 V
Default s/- 2
V
*1
The default setting changes when the settings for
A1-02 [Control Method]
and
o2-04 [Drive KVA Selection]
change.
*2
The default setting changes when the settings for
A1-02 [Control Method]
and
E1-03 [V/f Pattern Selection]
