188.21 Connect underfrequency
limit
Sets limit that is used only on connecting to the
grid. When the inverter is connected, this limit is
disabled. See parameter 188.20 Connect
underfrequency type.

188.22 Connect overfrequency
type
Selects connection type for overfrequency
protection.
Disabled
Disabled Limit is disabled. 0
Disconnected Limit is enabled when the inverter is disconnected
from the grid.
1
Reconnection Limit is enabled when inverter trips to
overfrequency.
2
188.23 Connect overfrequency
limit
Sets limit that is used only on connecting to the
grid. When the inverter is connected, this limit is
disabled. See parameter 188.22 Connect
overfrequency type.

188.24 Connect undervoltage type Defines how 188.25 Connect undervoltage limit
behaves.
• When enabled, grid connection is allowed only
when grid voltage is above the limit.
• When disabled, limit is not checked.

188.25 Connect undervoltage limit Sets the limit that is used only when the inverter is
not connected. The limit is disabled when the
inverter is connected. The purpose is to allow
different connect and disconnect limits. See
parameter 188.24 Connect undervoltage type.

188.26 Connect overvoltage type Defines how 188.27 Connect overvoltage limit
behaves.
• When enabled, grid connection is allowed only
when grid voltage is above the limit.
• When disabled, limit is not checked.

188.27 Connect overvoltage limit Sets the limit used only when the inverter is not
connected. The limit is disabled when the inverter
is connected. The purpose is to allow different
connect and disconnect limits. See parameter
188.26 Connect overvoltage type.
