I have voltronic inverter 3k fan  stops with code 01 its mean fan need a replacement  
old fan in  pic-01 its use [us62 ic][1]  so i order new fan pic-02 and its not working 
first reason the cables reversed gnd and signal and pulse are normally measured by connecting the signal and gnd on old fan but on the new one it's not 
it can measure only by  conneст  signal and vcc
 also signal is reversed  its use  [LB11967V][2] driver on RD pin 

my question how can to reverse the signal and measure it with signal and gnd
