1: Frequency arrival signal (FAR)
Refer to the function description of F6.18.
2: Frequency level detection signal (FDT1)
Refer to the function description of F6.14~F6.15.
3: Frequency level detection signal (FDT2)
Refer to the function description of F6.16~F6.17.
4: Overload detection signal (OL)
If the output current of the drive exceeds FA.12 overload detection level, and the time
is longer than FA.13 overload detection time, it will output an indication signal. Usually used
for overload pre-alarm. See the description of Figure 6-55 in group FA.
5: Undervoltage lockout stopping (LU)
When the DC bus voltage is lower than the undervoltage limit level, an indication
signal is output, and the LED displays “P.oFF”.
6: External fault stop (EXT)
When the drive has an external fault trip alarm (E015), it outputs an indication signal.
7: Frequency upper limit (FHL)
When the set frequency ≥ the upper limit frequency and the operation frequency
reaches the upper limit, an indication signal is output.
8: Frequency lower limit (FLL): When the set frequency ≤ the lower limit frequency and
the operation frequency reaches the lower limit, an indication signal is output.
