0~10000S 

During the full-water warning, if the detected 
full-water signal is cleared

，

the delay 

counts

，

after the time set by P15.14,the 

warning is cleared.

0.0~1000.0S 

Set the operation time of Dry-run operation. 
Under the continuous  Dry- run operation

，

the inverter will stop run

，

if the operation 

time is reached.

100% corresponds to the rated motor 
current. 

If the target frequency and the absolute 
value of the ramp frequency is less than or 

equal P15.19,and the current corresponding 
to the current frequency is less than P15.17, 
after the time set by P15.16, the inverter will 
stop run

；

otherwise,it will operate 

normally.If the state is not continuous,the 
delay counting will be cleared automatically.

P15.19 

Lag frequency 

threshold 

0.00~200.00H

z 

P15.19 is the lag frequency for the analysis 

of Dry-run operation. If the target frequency 
and the absolute value of the ramp 
frequency is less than or equal P15.19

，

the 

current will be compared.

Delay Time of 

Weak Light 

0.0~3600.0S 

If the output frequency is less than or equal 

to the lower limit of PI output frequency and 
the state lasts for the set value by P15.20, 

the inverter will stop run.If the state is not 
continuous

，

the delay counting will be 

cleared automatically. 
NOTE:If the PV voltage is lower than 
software undervoltage point

，

it will stop run 

and no need to wait for the set time. 
If P15.29=0,the system will 

switch

to the AC 

input when the light is weak.
