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.
F
(Determined by A1-02)
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.
• Parameter A1-03 [Initialize Parameters] will not reset the value of E1-03.
0 : Const Trq, 50Hz base, 50Hz max
Use this constant torque pattern for general applications. This pattern is used when the load torque is constant without
any rotation speed such as that used for linear conveyor systems.
Note:
The voltage values in the figures are for 200 V class drives. Multiply the values by 2 for 400 V class drives.
