Examples for changing parameters
Changing the acceleration time 1: PNU F002
The frequency inverter is in display mode: LED POWER is lit and the
display shows 0.0 Hz a.
X Press the PRG key.
The display changes to d001.
X Press the Down key seven times until F002 appears on the
display.
X Press the PRG key.
The PRG LED lights up.
The set acceleration time 1 in seconds appears on the display
(default value: 10.00).
X With the Up and Down arrow keys change the set values, for
example to 5.00.
Hold the Down key to change the display value at logarithmically
increasing step widths.
There are now two possibilities:
X Press the ENTER key to save the displayed value.
Press the PRG key to save the displayed value to non-retentive
memory. When the power supply is switched off (LED POWER off),
the value is lost.
F002 appears in the display and the PRG LED goes out.
X Press the UP button seven times until d0001 appears.
X Press the PRG key.
The value 0.0 appears again in the display and the Hz LED lights
up. You have reduced the acceleration time from 10 s to 5 s.
You can also change the parameter values of groups B and C and
H as described in the example.
Changing the maximum frequency: PNU A004
X Press the PRG key.
X Press the Down key until the main menu A--- shows in the
display.
X Press the PRG key.
The display shows A001.
X Press the Up key until A004 shows in the display.
X Press the PRG key.
The PRG LED lights up.The value set under PNU A004 appears in
the display (default value: 50).
X With the Up and Down arrow keys change the set values, for
example to 60 Hz.
As this is a limited operating parameter, you must press the
ENTER key to accept it. If you press the PRG key, the new value is
discarded.
The display shows A004.
X Press the PRG key until A--- shows in the display.
X Press the Up key until d001 shows in the display.
X Press the PRG key.
The frequency inverter changes to 0.0 Hz. You have changed the
maximum frequency to 60 Hz, i.e. the previous reference value of
0 to 50 Hz now corresponds with 0 to 60 Hz.At 50 Hz (PNU A003)
the maximum output voltage is reached. Between 50 Hz and
60 Hz only the output frequency, and therefore the motor speed,
changes.
