Goodrive170-PV Series Solar Pump Inverter Function parameter list
-41-
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 (lagging 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
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.

0.00–200.00Hz
P15.22 is the lagging frequency threshold,
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.
