n
n8-87: Output Voltage Limit Selection
Note: Parameter available in drive software versions PRG: 1018 and later.
Determines the method of the output voltage limit.
Use the feed-forward method if oscillation occurs in the constant output
range. There is normally no need to change this parameter from its default value.
No. Name Setting Range Default
n8-87 Output Voltage Limit Selection 0 or 1 0
Setting 0: Feedback Method
Setting 1: Feed-Forward Method
n
n8-88: Output Voltage Limit Switching Current Level
Note: Parameter available in drive software versions PRG: 1018 and later.
Sets the current level to switch the output voltage limit sequence. Set as a percentage of the motor rated current (E5-03).
There is normally no need to change this parameter from its default value.
No. Name Setting Range Default
n8-88 Output Voltage Limit Switching Current Level 0 to 400% 400%
n
n8-89: Output Voltage Limit Switching Current Hysteresis Width
Note: Parameter available in drive software versions PRG: 1018 and later.
Determines the hysteresis of the current level to
switch the output voltage limit sequence. Set as a percentage of the motor
rated current (E5-03).
No. Name Setting Range Default
n8-89 Output Voltage Limit Switching Current Hysteresis Width 0 to [n8-88] 3%
n
n8-90: Output Voltage Limit Switching Speed
Note: Parameter available in drive software versions PRG: 1018 and later.
Sets the speed level to switch the output voltage limit sequence. Set as a percentage of the maximum output frequency
(E1-04).
No. Name Setting Range Default
n8-90 Output Voltage Limit Switching Speed 0 to 200% 200%
n
n8-91: Id Limit for Output Voltage Limit Control
Note: Parameter available in drive software versions PRG: 1018 and later.
Sets the amount of pull-in current that flows through the motor while operating at constant speed. Set as a percentage of
the motor rated current (E5-03). Increase this setting if hunting occurs at constant speed.
No. Name Setting Range Default
n8-91 Id Limit for Output Voltage Limit Control -200 to 0% -50%
