V/F Pattern Selection
0 to 9, A to F <1>
F <2>
<1> This will not be reset by A1-03 (Reset).
<2> In Vector Control, d1-01 =F.
□ Preset V/F Pattern Selection (Setting Value 0 to E)
The preset V/F patterns are listed in Table 6.13. Select the appropriate V/F pattern and set to
this parameter. d1-02 to d1-11 cannot be edited.
Note:
1. An improper V/F could cause motor undertorque or increased current because of overexcitation.
2. d1-01 will not be reset by A1-03 (Reset).

7
60 Hz, square of derate
8
50 Hz, mid starting torque
High Starting
Torque
· Long wiring between the drive and motor
(more than 150 m)
· Large starting torque is required such as
elevators.
· AC reactor is installed on the drive output
side

50 Hz, high starting torque
A
60 Hz, mid starting torque
B
60 Hz, high starting torque
C
90 Hz (with 60 Hz base)
Fixed Output
Constant output voltage when running at
60 Hz and above.
D
120 Hz (with 60 Hz base)
E
180 Hz (with 60 Hz base)
The characteristics of the V/F patterns are illustrated in the following table. The table shows the
V/F patterns for 200V. The voltage will be doubled for 400V.
