Understanding Preset Frequencies
Preset frequency mode (P3.3.10)
You can use the preset frequency parameters to define certain frequency references in advance. These references
are then applied by activating/deactivating the digital inputs connected to parameters Preset frequency selection 0
(P3.5.1.15), Preset frequency selection 1 (P3.5.1.16) and Preset frequency selection 2 (P3.5.1.17). Two different
logics can be selected:

Binary coded
Combine activated inputs according to the table below to choose
the Preset frequency needed.

Number (of inputs
used)
You can apply the
Preset frequencies 1 to 3, depending on how
many of the inputs assigned for
Preset frequency selections are
active.
