n n8-63/n8-68: Output Voltage Limit Gain 1/2
n8-63 sets the gain for the output voltage limit in 0.01 units. n8-68 sets the voltage detection level adjustment gain. There is
normally no need to change these parameters from their default values.
No.
n8-63
n8-68
n n8-65: Speed Feedback Detection Control Gain during ov Suppression (for PM OLV)
Sets the gain for internal speed feedback detection control when overvoltage suppression is active. Although this setting rarely
needs to be changed, adjustment may be necessary under the following conditions:
• Increase this setting if motor oscillation or hunting occurs when ov suppression is active.
• Decrease this setting in increments of 0.05 to decrease the drive responsiveness during ov suppression.
No.
n8-65
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.
n8-87
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.
n8-88 Output Voltage Limit Switching Current Level
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.
n8-89 Output Voltage Limit Switching Current Hysteresis Width
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.
