Maximum Frequency
In the third step, the inverter tests the maximum frequency.
During the test sequence, the frequency limit applied is
shown in the display of the inverter.
The frequency limit is reduced successively until the shut-
down threshold is achieved and the inverter disconnects
from the grid.
Once the inverter has disconnected from the grid, the display successively shows the following values
one after the other:
• Disconnection value,
• Calibration value,
• Reaction time,
• Present grid frequency.
