<1> The braking transistor operation level.
■ V/F Pattern Setting( d1-01)
The set V/F pattern determines the output voltage according to the frequency command.
There are 15 different preset V/F patterns (setting 0 to E: only the maximum voltage and base
voltage can be changed) and user-defined V/F patterns d1-02 to d1-11 (setting F).
d1- 01 V/F Pattern Selection
Selects 1 V/F pattern from the preset 15 ones or sets the user-defined V/F pattern.
<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).

For general purpose applications such as
conveyors. The torque remains constant
regardless of the speed.
For applications such as fans, pumps and
other derated loads.
50 Hz, mid starting torque
· Long wiring between the drive and motor
(more than 150 m)
50 Hz, high starting torque
