Fan Cooling Control
Factory Setting: 3
Settings 0: Fan always ON
1: Fan will be OFF after the AC motor drive stops 1 minute
2: 2: When the AC motor drive runs, the fan is ON. When the AC motor drive
stops, the fan is OFF
3: Fan turns ON when the temperature attain around 60
o
C
 This parameter is used for controlling the fan.
 Setting 0: Fan will run immediately when the power of drive is turned ON.
 Setting 1: AC motor drive runs and fan will run.1 minute after AC motor drive stops, fan will be
OFF
 Setting 2: AC motor drive runs and fan will run. AC motor drive stops and fan will stop
immediately
 Setting 3: When temperature of IGBT is higher than 60 degrees, fan will run. When temperature
of IGBT is lower than 40 degrees, fan will stop.

 When the multi-function input terminal is set to EF (10) or forced stop (18) and the terminal
contact is ON, the drive will stop according to the setting of this parameter.

Auto Voltage Regulation (AVR) Function
Factory Setting: 0
Settings 0: Enable AVR
1: Disable AVR
2: Disable AVR during deceleration
 The rated voltage of the motor is usually AC 220V / 200 V, 60 Hz / 50 Hz, and the input voltage
of the AC motor drive may vary from AC 180 V to 264V, 50 Hz / 60 Hz. Therefore, when the AC
motor drive is used without AVR function, the output voltage will be the same as the input
voltage. When the motor runs at the voltage exceeding 12 % ~ 20 % of rated voltage, it will
cause higher temperature, damaged insulation and unstable torque output, which will result in
losses due to shorter lifetime of motor.
 AVR function automatically regulates the output voltage of AC motor drive to the motor rated
voltage. For example, if V/F curve is set at AC 200V / 50 Hz and the input voltage is at AC 200V
to 264V, then output voltage to the motor will automatically be reduced to a maximum of AC
200V / 50 Hz. If the input voltage is at AC 180V to 200V, the output voltage to motor and input
power will be in direct proportion.
