5-3 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.
