VOLTAGE/FREQUENCY (V/F) CHARACTERISTIC SETTING
V/F (base frequency) @ Base frequency voltage (13 (91
Base frequency (frequency at the rated motor torque) can be set in accordance
with the motor rating within the range’ from 50Hz to 360Hz.
In the case of 2200 series, output voltage at the base frequency can be also
set. When set putout voltage is below the power supply voltage, the maximum
output reference of inverter is equal to output voltage set by user.
