Ref.
S1-01
(3200)
Dynamic Noise Control Sets the function that decreases the output voltage in variable torque applications to
decrease audible noise.
0 : Disabled
1 : Enabled

S1-02
(3201)
Voltage Reduction Rate Sets the rate at which the drive will decrease the output voltage as a percentage of the V/f
pattern when operating with no load.
50.0%
(50.0 - 100.0%)
376
S1-03
(3202)
Voltage Restoration Level Sets the level at which the drive will start to restore the voltage as a percentage of the drive
rated torque.
20.0%
(0.0 - 90.0%)
376
S1-04
(3203)
Voltage Restoration Off
Level
Sets the level at which voltage restoration for the V/f pattern is complete as a percentage of
the drive rated torque. If the output is more than S1-04, the drive will control the voltage as
specified by the V/f pattern setting.
Note:
The lower limit of this parameter is the value of S1-03 [Voltage Restoration Level] +
10.0%.
50.0%
(10.0 - 100.0%)

Volt Restore Sensitivity
Time K
Sets the level of sensitivity of the output torque and LPF time constant for the voltage
reduction rate. You can adjust the level of sensitivity with the load response.
1.000 s
(0.000 - 3.000 s)
376
S1-06

Volt Restore Impact Load
Time K
Sets the voltage restoration time constant when you add an impact load. 0.050 s
(0.000 - 1.000 s)
376
S1-07
(324C)
Output Phase Loss Level Decreases the output phase loss level when Dynamic Noise control is active. 100.0%
(10.0 - 100.0%)
