The following voltage limits can be changed:
n
Upper disconnection value 1)
n
Lower disconnection value 1) (Fig. left)
1)
The disconnection value relates to the peak value of the voltage.
The following frequency limits can be changed:
n
Upper disconnection value
n
Lower disconnection value (Fig. left)
n
Derating switch-on threshold (because frequency is too high)
n
Frequency threshold when switching on again
The following voltage limits can be changed:
n
Upper disconnection value
1)
(Fig. left)
n
Lower disconnection value 1)
1) The disconnection value relates to the average value of the voltage.
Overview:
The reactive power characteristic curve must be set during 1st commis‐
sioning if this is prescribed for the previously selected country. The fol‐
lowing applies:
n
3 characteristic curves are available for selection (Fig. left):
–
Default. char. curve
(pre-defined)
–
Enter char. curve
(manually adjustable)
–
Char. curve cos φ = 1
(pre-defined)
n
After configuration, the characteristic curve is displayed as a graph
(example in Fig. left).
①
x-axis, output power P in %
②
y-axis, phase shift cos φ
③
Nodes (in example: 4 nodes)
④
Arrow symbol
Overexcitation
⑤
Arrow symbol
Underexcitation
