◆If collectors are selected as PLC running steps output or fault output, D0, Y1, Y2 must
be selected as the same function (26, or 27) to make the combination effective.
◆Fault type and running steps refer to Table 5-3-4.

Setting Function Description
0 NULL None
1 RUN
The inverter is in running state, the output of terminal is
valid.
2
FAR Frequency
arriving
Refer to description of parameters P3.18 (Frequency
arriving signal (FAR)).
3
FDT Frequency
detection
Refer to description of parameters P3.19 (FDT
level) ,P3.20 (FDT lag).
4
FDTH Frequency
upper limit
arriving
When the reference frequency is higher than upper
limit of frequency, if the operating frequency reaches
the frequency upper limit and delays, the output of
terminal is valid.
5
FDTL Frequency
lower limit
arriving
If the reference frequency is below the lower limit of
frequency and the operating frequency reaches the
lower limit of frequency, the output of terminal is valid.
6
Upper and lower
limits of wobble
frequency
If wobble frequency operating function is selected and
the wobble frequency is higher than upper limit of
frequency (P0.08) or lower than the lower limit of
frequency (P0.09). The output of terminal is valid.
7
Zero-speed
running
If the output frequency is 0 and the inverter is in
running state, the output of terminal is valid.
