Input AC Supply Voltage
Sets the drive input voltage.
NOTICE: Set parameter E1-01 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.
0 : Const Trq, 50Hz base, 50Hz max
1 : Const Trq, 60Hz base, 60Hz max
2 : Const Trq, 50Hz base, 60Hz max
3 : Const Trq, 60 Hz base, 72 Hz max
4 : VT, 50Hz, 65% Vmid reduction
5 : VT, 50Hz, 50% Vmid reduction
6 : VT, 60 Hz, 65% Vmid reduction
7 : VT, 60 Hz, 50% Vmid reduction
8 : High Trq, 50Hz, 25% Vmin Boost
9 : High Trq, 50Hz, 65% Vmin Boost
A : High Trq, 60 Hz, 25% Vmin Boost
B : High Trq, 60 Hz, 65% Vmin Boost
C : Const Trq, 60 Hz base, 90 Hz max
D : Const Trq, 60 Hz base, 120 Hz max
E : Const Trq, 60 Hz base, 180 Hz max
F : V/f Pattern Selection
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.
