Goodrive100-PV Series Solar Pumping VFD Function parameters

Detailed illustration of parameters
underload detection of the pumping
VFD.
If it is not 0.0%, it is determined by
P15.20. 100.0% corresponds to the
rated current of the motor.
If the target frequency and the absolute
value of the ramp frequency is less than
or equal to P15.22, and the current is
less than P15.20, after the time set by
P15.19, underload fault is reported.
Otherwise, it will be operated normally.
If the state is not continuous, the delay
counting will be cleared automatically.
0.0–1000.0s
This parameter is used to set the
underload reset delay.
The operation time and reset time are
counted at the same time during
underload, and it is generally bigger
than P15.19 so as to ensure underload
prealarm is reported after underload
delay operation time is reached. After
the time set by P15.21-P15.19, it is
reset. If the value is the same as
P15.19, it is automatically reset when
underload prealarm is reported.
0.00–200.00Hz
P15.22 is the lag frequency threshold
