Definition of Over-
frequency Response Parameters
Description
The Start frequency value for over-frequency response.
The Stop frequency value for over-frequency response.
Fstop 51.50Hz <<
Fstr 50.50Hz
This series inverter provides “over-frequency response” func�on.
Long pressing the “OFD Mode” to enter the “over-frequency response”
se�ng menu.
For example, StrtPT: 50.5Hz, StopPT:
51.5Hz, RecPT: 50.1Hz, when the grid
frequency increases beyond Start: 50.5Hz,
the inverter will linearly reduce the power
output with a gradient of 100% Pmax/Hz
un�l it reaches StopPT: 51.5Hz .
Rate of Power recovery(Percentage of active power)
In hysteresis mode, power is restored only when
it is below this frequency
