Input AC Supply
Voltage
Sets the drive input voltage.
NOTICE: Set this parameter to align with the drive input
voltage (not motor voltage). The protective features of the
drive will not function if this parameter is incorrect. Failure to
obey will cause incorrect drive operation.

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, 60Hz base, 72Hz max
4 : VT, 50Hz, 65% Vmid reduction
5 : VT, 50Hz, 50% Vmid reduction
6 : VT, 60Hz, 65% Vmid reduction
7 : VT, 60Hz, 50% Vmid reduction
8 : High Trq, 50Hz, 25% Vmin boost
9 : High Trq, 50Hz, 65% Vmin boost
A : High Trq, 60Hz, 25% Vmin boost
B : High Trq, 60Hz, 65% Vmin boost
C : High Freq, 60Hz base, 90Hz max
D : High Freq, 60Hz base, 120Hz max
E : High Freq, 60Hz base, 180Hz max
F : Custom
Note:
• When A1-02 = 2 [Control Method Selection = Open Loop
Vector], settings 0 through 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.
