FbEq Description
1 The maximum increase rate of active power is defined by
parameter 42.18 MPPT P RAMP
Defines the maximum increase rate for active power in the MPPT
mode.
1 = 1%/ Maximum increase rate for active power in the MPPT mode.
min
Defines the stopping ramp rate for active and reactive power in a
controlled stop. A controlled stop means that the inverter is
stopped without a fault.
Both active and reactive power are ramped down to zero using this
ramp rate before the inverter is totally stopped.
100 = Ramp rate. 100%/s equals parameter 04.06 NOMINAL POWER in
1%/s one second.
Parameters related to internal grid monitoring.
Note: Group 44 is write-protected. It can be write-enabled by
giving a password with parameter 16.03 PASS CODE.
Selects the input for grid voltage monitoring.
0 Grid monitoring for undervoltage and overvoltage is based on the
positive sequence component of the grid voltage.
1 Undervoltage detection is based on the minimum RMS value and
overvoltage detection on the maximum RMS value of the grid
voltage.
The selection between phase-to-neutral and phase-to-phase
voltages is done with parameter 40.24 RMS VOLTAGE CALC.
Parameters for active power limitation during a grid
underfrequency situation.
Enables or disables active power limitation during a grid
underfrequency situation.
0 Active power limitation during a grid underfrequency situation is
disabled.
1 Active power limit increases according to the grid underfrequency
characteristic curve, but decreases only when the grid frequency
has been greater than
46.02 UF PLIM RET
done with a ramp rate defined by parameter
RAMP.
Defines the return delay for a grid underfrequency situation. The
grid frequency has to be greater than
for the duration of this delay before return ramping can be started.
20 = 1 s Return delay
Defines the ramp rate for decreasing the active power limit after a
grid underfrequency situation.
20 = 1 s Ramping time from zero to 04.06 NOM AC POWER
Defines the return frequency for a grid underfrequency situation.
