Parameter
Meaning
QUX1
Start of the first section of the Q(U) characteristic on
the voltage axis. The parameter is entered in V.
Example: The characteristic begins at 190 V
the
value of QUX1 is 190.
QUY1
Power factor at the start of the Q(U) characteristic. If
the grid voltage falls below the value defined by QUX1,
the characteristic is limited to the value set in QUY1.
The setting is to be found in Table 10.
QUX2
End of the first section of the Q(U) characteristic on the
voltage axis. The parameter is entered in V. Example:
The first section of the characteristic ends at 220 V
the value of QUX2 is 220.
QUY2
Power factor at the end of the first section of the Q(U)
characteristic. If the grid voltage increases beyond the
value defined by QUX2, the characteristic is limited to
the value set in QUY2. The setting is to be found in
Table 10. Normally the parameter is set to 0, i.e. no
reactive power is produced.
QUX3
Start of the second section of the Q(U) characteristic
on the voltage axis. The parameter is entered in V.
Example: The characteristic begins at 235 V
the
value of QUX3 is 235.
QUY3
Power factor at the start of the Q(U) characteristic. If
the grid voltage falls below the value defined by QUX3,
the characteristic is limited to the value set in QUY3.
The setting is to be found in Table 10. Normally, the
parameter is set to 0, i.e. no reactive power is
produced.
QUX4
End of the second section of the Q(U) characteristic on
the voltage axis. The parameter is entered in V.
Example: The second section of the characteristic ends
at 240 V
the value of QUX4 is 240.
QUY4
Power factor at the end of the first section of the Q(U)
characteristic. If the grid voltage increases beyond the
value defined by QUX4, the characteristic is limited to
the value set in QUY4. The setting is to be found in
Table 10.
