Basic functions
Input/display frequency value
PNU F01
indicates the current setpoint frequency or the current fixed
frequency. You can change the frequencies with the arrow keys
and save them according to the setting in PNU A001 and the
frequency stages FF1 to FF4 (digital inputs) (
a
section “Fixed
frequency selection (FF1 to FF4)”, page 68).
With PNU F001, you can modify parameters, even when
parameter protection (PNU b031) has been set (
a
page 81).
Input/indication of frequency setpoint value
If you have not activated any fixed frequencies, PNU F001
indicates the setpoint frequency.
The setpoint frequency can be assigned in one of three ways,
depending on the setting under PNU A001:
• through the installed potentiometer on the keypad,
PNU A001 = 00;
• through analog inputs, PNU A01 = 01 (default):
– O (0 to 10 V),
– O2 (–10 V to +10 V) or
– OI (4 to 20 mA),
• through PNU F001 or PNU A020, PNU A001 = 02.
If you specify the setpoint frequency with PNU A020,
(
a
page 107), you can enter a new value under PNU F001,
which is saved automatically in PNU A020:
X
To change the value, use the UP and DOWN arrow keys.
X
Save the modified value with the ENTER key.
The saved value is automatically written to PNU A020.
Displaying/entering fixed frequencies
If you have activated the fixed frequencies with functions FF1 to
FF4 of the digital inputs, PNU F001 displays the selected fixed
frequency.
For details about changing the fixed frequencies, see
section “Entering the fixed frequencies in PNU F001”, page 68.
Acceleration time 1
Acceleration time 1 defines the time in which the motor reaches its
end frequency after a start signal is issued.

The setpoint can be defined using various methods:
• With PNU F001 or A020: Enter the value 02 under
PNU A001.
• Using the potentiometer on the keypad: Enter the value
00 under PNU A001.
• With a 0 to 10 V or a –10 to +10 V voltage signal or a 4 to
20 mA current signal at input terminals O or OI: Enter the
value 01 under PNU A001.
• With the digital inputs configured as FF1 to FF4. After
selection of the required fixed frequency stage using FF1
to FF4, the frequency for the respective stage can be
entered.
The display of the setpoint value is independent of which
method was used to set the setpoint value.
