0–10000s
Time setting on empty-water level
wake-up delay. (This parameter is still
valid for digital empty-water signal.)
0.0–1000.0s
Duration in which the water pump runs 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.
When the absolute value of target
frequency minus ramp frequency is less
than or equal to P15.22 (lag frequency
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 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 reset delay are performed
