Minimum Frequency
After the maximum frequency test, the minimum frequency
test takes place and the inverter shows the adjacent
display message for 5 seconds.
During the test sequence, the frequency limit applied is
shown in the display of the inverter. The frequency limit is
increased successively until the shutdown threshold is
reached and the inverter disconnects from the grid.
Once the inverter has disconnected from the grid, the display successively shows the following values,
each for 10 seconds:
• Disconnection value,
• Calibration value,
• Reaction time.
The change between the first and second display takes places every 2.5 seconds.
6.1.3 Interruption of the Self-Test
If, during the self-test, an unexpected disconnection requirement occurs, the self-test is interrupted. The
same applies if the DC voltage is so low that the feed-in can not be continued.
• The inverter then shows the adjacent display
message for 10 seconds.
• Restart the self-test as described in the following section 6.1.4 ”Restarting the Self-Test”
(page 57).
