■ n8-88: Vout Limit Switching Level
No.
(Hex.)
Name Description
Default
(Range)
n8-88
(02BD)
Vout Limit Switching Level
Sets the current level at which output voltage limit sequence selection occurs as a percentage
where the motor rated current is 100%. Normally there is no need to change this setting.
400%
(0 - 400%)
■ n8-89: Vout Limit Switching Hysteresis
No.
(Hex.)
Name Description
Default
(Range)
n8-89
(02BE)
Vout Limit Switching
Hysteresis
Sets the hysteresis width of the current level at which output voltage limit sequence selection
occurs as a percentage where the motor rated current is 100%. Normally there is no need to
change this setting.
3%
(0 - 400%)
■ n8-90: Vout Limit Switching Speed
No.
(Hex.)
Name Description
Default
(Range)
n8-90
(02BF)
Vout Limit Switching Speed
Sets the speed level at which output voltage limit sequence selection occurs as a percentage where
the maximum output frequency is 100%. Usually it is not necessary to change this setting.
200%
(0 - 200%)
■ n8-91: Id Limit at Voltage Saturation
No.
(Hex.)
Name Description
Default
(Range)
n8-91
(02F7)
Id Limit at Voltage
Saturation
Sets the limit value of feedback output voltage limit Id operation. Enabled when n8-87 = 0
[Output Voltage Control Selection = Speed Feedback Form]. Usually it is not necessary to change
this setting.
-50%
(-200 - 0%)
■ n8-94: Flux Position Estimation Method
No.
(Hex.)
Name Description
Default
(Range)
n8-94
(012D)
Expert
Flux Position Estimation
Method
Sets the criteria that the drive uses to find changes in speed or load. Usually it is not necessary to
change this setting.
1
(0, 1)
0 : Softstarter
1 : Speed Feedback
Set n8-57 = 1 [HFI Overlap Selection = Enabled] to enable this parameter. Increases the stability when the speed
or load suddenly change, for example with rapid acceleration/deceleration or impact loads.
■ n8-95: Flux Position Est Filter Time
No.
(Hex.)
Name Description
Default
(Range)
n8-95
(012E)
Expert
Flux Position Est Filter
Time
Sets the time constant of the filter used for the recognition criteria value for speed and load
changes. Usually it is not necessary to change this setting.
30 ms
(0 - 100 ms)
Note:
Enabled when n8-94 = 1 [Flux Position Estimation Method = Speed Feedback].
◆ nA: PM Motor Control Tuning
nA parameters make adjustments for controlling PM motors.
