 Setting the V/f Pattern
Using the E1- parameters the Inverter input voltage and the V/f pattern can be set as needed. It is not rec-
ommended to change the settings when the motor is used in open loop vector control mode.

Setting Inverter Input Voltage
Set the Inverter input voltage correctly in E1-01 so that it matches the power supply voltage. The set value
becomes a reference value for the stall prevention during deceleration and the overvoltage level according to
the table below.
Setting V/f Pattern
The V/f pattern can be selected using parameter E1-03. There are two methods of setting the V/f pattern:
Select one of the 15 preset pattern types (set value: 0 to E), or set a user-defined V/f pattern (set value: F).
The factory setting for E1-03 is F.
To select one of the existing patterns, refer to the following table.
