S1-02
(3201)
Voltage Reduction Rate
Sets the rate at which the output voltage will be reduced as a percentage of the
V/f pattern when operating with no load.
Default: 50.0%
Min.: 50.0
Max.: 100.0
274
S1-03
(3202)
Voltage Restoration Level
Sets the level when the drive should start restoring the voltage as a percentage
of the drive rated torque.
Default: 20.0%
Min.: 0.0

274
S1-04
(3203)
Voltage Restoration
Complete 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 torque rises above the value
of S1-04, then the voltage will be controlled in a manner specified by the V/f
pattern setting.
