EFERENCE
Maximum frequency reference.

Preset Freqs
You can use the preset frequency parameters to define certain frequency references in advance.
These references are then applied by activating/inactivating digital inputs connected to parameters
P3.3.3.10, P3.3.3.11 and P3.3.3.12 (
Preset Freq Sel0, Preset Freq Sel1
and
). Two
different logics can be selected:

Value ‘0’ selected for parameter P3.3.3.1:
Preset frequency 0 can be chosen as reference by selecting value 1 for parameter P3.3.1.5.
Other preset frequencies 1 to 7 are selected as reference by dedicating digital inputs for parame-
ters P3.3.3.10, P3.3.3.11 and/or P3.3.3.12. Combinations of active digital inputs determine the used
preset frequency according to Table 141 below.
The values of the preset frequencies are automatically limited between the minimum and maxi-
mum frequencies (P3.3.1.1 and P3.3.1.2). See table below.
Preset frequencies 1 to 7:
