    Hi, 
    
 
    I was going through the sample c code provided for motor control (Isoinv_VF).
    
 
    In the scalarControl.c file, gain factors Current_sincOffGainFactor and Current_sincGainFactor have been used. Current_sincGainFactor formula is given in AD7403 application note. But Current_sincOffGainFactor  formula is not there.
    
 
    Can anyone tell from where it has been derived?
    
 
    How can i validate if the current as measured by AD7403 is correct or not?
    
 
    regards
