NOTE 1: The initial value of carrier frequency
varies with the inverter capacity.
When VP1 to VP3 is selected,carrier
frequency is automatically changed to
VT.
Set the frequency commands (voltage frequency command (O-L terminal signal), current frequency
command (OI-L terminal signal), and the number of samplings.
FUNC

Set the output frequency of each multispeed speed. When setting four or more speeds, refer to the
item of output frequency setting.
