Pull-in Current @
Deceleration
Sets the pull-in current that can flow during deceleration as a percentage of the E5-03
[PM Motor Rated Current (FLA)] .
Note:
When n8-79 = 0 , the drive will use the value set in n8-51 [Pull-in Current @
Acceleration] .

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.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the motor
rated current.
• A1-02 = 5, 6 [OLV/PM, AOLV/PM]: E5-03 [PM Motor Rated Current (FLA)]
• A1-02 = 8[EZOLV]: E9-06 [PM Motor Rated Current (FLA)]

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.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the motor
rated current.
•
A1-02 = 5, 6 [OLV/PM, AOLV/PM]: E5-03 [PM Motor Rated Current (FLA)]

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.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the
maximum output frequency.
• A1-02 = 5, 6 [OLV/PM, AOLV/PM]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Motor Max Revolutions]
