Input AC Supply Voltage
Sets the drive input voltage.
NOTICE: Damage to Equipment. Set E1-01 [Input AC Supply
Voltage] to align with the drive input voltage (not motor
voltage). If this parameter is incorrect, the protective functions
of the drive will not operate correctly and it can cause damage
to the drive.

V/f Pattern Selection
Sets the V/f pattern for the drive and motor. You can use one of the preset patterns or
you can make a custom pattern.

E : High Freq, 60Hz base, 180Hz max
F : Custom
Note:
• When A1-02 = 2 [Control Method Selection = OLV], settings 0 to E are not
available.
• Set the correct V/f pattern for the application and operation area. An incorrect V/f
pattern can decrease motor torque and increase current from overexcitation.
