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.
200 V Class: 240 V,
400 V Class: 480 V
(200 V Class: 155 to 255 V,

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.

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.
