Basic parameters
Input/indication of reference frequency
PNU F01
indicates the current reference frequency or the current fixed
frequency. You can change the frequencies with the arrow keys
and save the settings as defined with PNU A01 and the fixed
frequency stages CF1 to CF4 (digital inputs) (a section “Fixed
frequencies”, page 97).
With PNU F01, you can change the reference value even when
parameter protection has been set with PNU b31.
If you have not activated any fixed frequencies, PNU F01 indicates
the set reference frequency.
If you specify the setpoint frequency with PNU A020, you can
enter a new value under PNU F001, which is saved automatically
in PNU A020:
X Change the current value with the arrow keys.
X Save the modified value with the ENTER key.
The saved value is automatically written to PNU A020.

The reference value can be defined using various methods:
• With PNU F001 or A020: Enter the value 02 under PNU A001.
• With the potentiometer on the keypad: Enter the value 00 under
PNU A01.
• With a 0 to 10 V voltage signal or a 4 to 20 mA current signal at
analog input O or OI: Enter the value 01 under PNU A01.
• With the digital inputs configured as CF1 to CF4. After selection of
the required fixed frequency stage using CF1 to CF4, the frequency
for the respective stage can be entered.
The display of the reference value is independent of which method was
used to set the reference value.
