P15.20, the system reports the underload
fault with a delay specified by P15.19.
Otherwise, the system runs properly. In the
non-continuous situation, the delay counter
is automatically cleared.
0.0–1000.0s
Underload reset delay.
In underload state, the counting on the
underload run time and that on the
underload
synchronously. Generally, the value needs
to be greater than P15.19 so that the
system can report the underload alarm
when the underload run time is reached and
then reset can be performed when the time
P15.21–P15.19 elapsed. If the value of
P15.21 is the same as that of P15.19, auto
reset is performed at the same time as the
underload alarm is reported.

used to determine the underload run
condition. Currents are compared only
when the absolute value of target frequency
minus ramp frequency is continuously less
than or equal to this parameter.
0.0–3600.0s
Time setting on weak-light delay.
When the output frequency is less than or
equal to the PI output frequency lower limit
and the delay counting is started, which
reaches the weak-light delay time, the
delay system reports the weak-light alarm (A-LS)
and then sleeps. In the non-continuous
situation, the delay counter is automatically
cleared.
