Basic functions
Input/display frequency value
PNU F001 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
fixed frequency steps FF1 to FF4 (digital inputs) (
a
Section
“Fixed frequency selection (FF1 to FF4)“, Page 69).
With PNU F001, you can modify parameters even though the para-
meter protection PNU b031 is set (
a
Page 83).
Display/input frequency setpoint value
If you have not activated any fixed frequencies, PNU F001 displays
the frequency setpoint value.
The frequency setpoint value can be assigned in one of three ways,
dependent on 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 123), you can enter a new value under PNU F001,
which is automatically saved to PNU A020:
X
Change the present value with the 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 through functions FF1
to FF4 of the digital inputs, PNU F001 indicates the selected fixed
frequency.
For details about changing the fixed frequencies,

Section
“Entering the fixed frequencies in PNU F001”, Page 71.
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.
• With 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.
