Voltage limits ø (average value)
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.
Reactive power characteristic curve
Overview:
The reactive power characteristic curve must be set during 1st commissioning if this is prescribed for
the previously selected country. The following 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
Technical details
n Each characteristic curve is defined by 2 to 8 nodes.
n A node is defined by the output power P of the inverter (x-axis) and the associated phase shift
(y-axis).
