The bigger the value is, the stronger the effect and 
faster the adjustment is. 
0.00–100.00 
The proportion coefficient 2 of the target frequency 
The bigger the value is, the stronger the effect and 
faster the adjustment is. 
0.00–100.00 
The integral coefficient 2 of the target frequency 
The bigger the value is, the stronger the effect and 
faster the adjustment is. 
0.0–6553.5V DC 
If  the  absolute  value  of  bus  voltage  minus  the 
reference value is bigger than P15.10, it will switch 
to P15.08 and P15.09; otherwise it is P15.06 and 
P15.07. 
0: Digital input of the water-level control   
If the function  code  is  0, the water-level signal is 
controlled  by  the  digital  input.  See  45  and  46 
functions of  S terminal  for  detailed information.  If 
the full-water signal is valid, the system will report 
the  warning  (A-tF)  and  sleep  after  the  time  of 
P15.13. During the warning, the full-water signal is 
invalid and the system will clear the warning after 
the  time  of  P15.14.  If  the  empty-water  signal  is 
valid, the system will report the warning (A-tL) and 
sleep after the time of P15.32. During the warning, 
the empty -water signal  is invalid and the system 
will clear the warning after the time of P15.33.(the 
function codes of P15.13, P15.14, P15.32, P15.33 
are related to the water-level control)
