[10] Setup level for control of the grid voltage increasing
This is a function to prevent increasing of the grid voltage by controlling the output current when the grid voltage
increases. This function can control the voltage of the inverter terminal before reaching OV level.
Setup level for control of the grid voltage increasing can decide the level of the grid voltage that controls the
output current. The level for control of the grid voltage increasing is a level which decreases Setup level from the
OV level.
[11] Setup of Output Signal 1
The output mode of "External output signal 1 (AUX_OUT1)" is set.
Set the output mode of signal according to the occurring error.
Refer to " Appendix -1 Error list " for the error that occurs when each MODE is set.
[12] Setup of Output Signal 2
The output mode of "External output signal 2 (AUX_OUT2) is set. Refer to the following table.

The voltage of
the inverter terminal : Vo
The grid voltage : Vgrid
The grid impedance : Z
The output current : Io
Vo = Vgrid + Z x Io
Vo is higher than Vgrid
Time
The voltage of the inverter
OV level
Setup level for control
of grid voltage increasing
If the voltage of the inverter is higher than threshold, the
inverter control the voltage by reducing output current
[An example]
The voltage level for control of grid voltage increasing becomes
251V when the OV level is 253V, and Setup level for control of
grid voltage increasing is -2.0V.
