6.2.5 Preset Speed Main Frequency Setting
NVF5 can realize 15 preset frequency at most，assigns 4 digital inputs used to select
as frequency reference.Also can be selected less than 4 DI to configure preset speed，For
missing bits, state 0 is calculated.
When the main frequency reference is preset speed, the function selection of DI
terminal should be set to the value of 24-27, that is, the input terminal of preset speed
should be specified.The Multi-Preset Frequency can be set in parameter group FA，see
below parameter setting：

The scale of preset speed is the percentage of Max. frequency F0.07. The positive
and negative parameters determine the direction of operation. If the value is negative, it
means the inverter runs in the opposite direction.
Assigns 4 digital inputs as preset frequency input channel - K1～K4，and compose 4
binary digits：Among them, 1 means effective, and 0 means ineffective.
The state can be combined into 15 states. These 15 states correspond to 15 setting
values.See below figure:
