V/f Control

With V/f control, the user must set the Inverter's input voltage, motor selection, rated
current, and V/f pattern.

5-3-1 Setting the Motor Parameters

H Inverter Input Voltage Setting (E1-01)
Set the Inverter's input voltage (E1-01) to match the power supply voltage; it cannot be changed during
operation. This setting is used as the reference value for functions such as the protection functions.

E1-01 Input Voltage
Note The voltage settings shown in parentheses are the values for the 400-V class.
H Motor Selection and Rated Current Setting (E1-02 and E2-01)
Set the type of motor being used with the motor selection parameter (E1-02). This setting is a reference
for the protection functions. This parameter cannot be changed during operation.
