y0.16
Clean up the delay time of
overtank pre-warning
0
～
10000s
Default: 600s
y0.17
Reservoir full of water control
0.0
～
100.0
Default: 25.0%
y0.18
Dormancy delay time of
reservoir full of water
pre-warning
0
～
10000s
Default: 60s
When the detected water level control analog signal is lesser than water level threshold (y0.17),
and this state is continued over the delay time of y0.18, the pre-warning of water-full (Arn34) is
reported and system enters dormant state.
In water-full pre-warning, when the detected water level control analog signal is larger than y0.17,
delay time begins, and this state is continued till the delay time of y0.16. The full-water pre-warning is
cleared and normal operation is restored.
Attention: If any terminal function is set as 52 and the terminal input state is valid, overtank
or dry run function will be active.
When this terminal is valid, this state is continued over the delay time of y0.18, the pre-warning of
water-full (Arn34) is reported and system enters dormant state.
When this terminal is invalid, this state is continued till the delay time of y0.16. The full-water
pre-warning is cleared and normal operation is restored.
y0.19
Detection of reservoir
hydraulic probe
0.0
～
100.0
Default: 0.0%
0.0% means Null.
When entered value is not 0.0% and when the detected water level control analog signal is larger
than y0.19 hydraulic probe damaged point, hydraulic probe fault (Err32) will be reported and drive will
stop.
y0.20
Current level of pump
under-load pre-warning.
0.0
～
100.0% 0.0: Null
Default: 0.0%
y0.21
Delay time of pump
under-load pre-warning.
0.0
～
1000.0s
Default: 60.0s
y0.22
Delay time of pump
under-load resetting.
0.0
～
1000.0s
Default: 60.0s
0.0%: Automatic detection of under-load, decided by under-load detection of inverter.
For non-zero value, it is decided by y0.20 parameter setting, 100% corresponds to rated current
of motor.
When absolute value of the difference between target frequency and slop frequency is less than
or equal to y0.23 lag frequency threshold and if the current value continues to be less than y0.20 set
value, over the y0.21 pump under-load delay time, under-load pre-warning(Arn25) is reported.
After y0.22 under-load reset time, under-load pre-warning is restored.
y0.23
Lag frequency threshold
0.00
～
200.00Hz
Default :0.30Hz
It is used for adjusting the condition of under-load operation. When absolute value of the
difference between target frequency and slop frequency continues to be less than or equal to lag
frequency threshold, current comparison is done.
