Medium Load Id Current
Sets the level of the pull-in current as a percentage, where E5-03 [PM Motor Rated
Current (FLA)] = 100% .

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] .

Output Voltage Limit
Method
Sets the method of output voltage limit. If there is vibration in the constant output range,
set Feedforward Method. Usually it is not necessary to change this setting.

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]
