valid for digital empty-water signal.)
0.0–1000.0s
Duration in which the water pump runs in
run time in underload state. In continuous underload
condition, the underload alarm (A-LL) is
reported when the run time is reached.
0.0%: Automatic detection on underload
0.1–100.0%
The value 0.0% indicates it is determined
by the underload detection mechanism of
the inverter.
A value rather than 0.0% indicates it is
determined by P15.20. 100.0%
corresponds to the motor rated current.
Current
When the absolute value of target
frequency minus ramp frequency is less
than or equal to
running
threshold): If the actual current value at
the actual frequency is continuously less
than 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

0.0–1000.0s
Underload reset delay.
Underload
In underload state, the counting on the
reset delay
underload run time and that on the
underload reset delay are performed
