In a noisy environment, it is advantageous to use negative bias to provide a noise margin. It is
recommended NOT to use less than 1V to set the operation frequency.

Parameters 03-03 to 03-11 are used when the source of frequency command is the analog
voltage/current signal.

Settings
There are two AVI analog inputs can be used when this parameter is set to 1 and the SW2 on
the control board is set to AVI2. At this moment, ACI is for voltage input.
