(Note) If this value is 0, internally this value is worked as (32 – No.2528).
Dynamic characteristic compensation Gx is composed from three parameters No.2526, No.2527, No.2528,
and No.2529, which symbols are GODMX, GODMN, GCOEF, and EXGXK2 respectively.
Usually you should set the followings value. GCOEF = 64, EXGXK2 = -32
• In case of HRV2, GODMX = 12, GODMN = 0.
• In case of HRV2 and No.2017#7 = 1, GODMX = 10, GODMN = 0.
• In case of HRV3 and No.2017#7 = 1, GODMX = 8, GODMN = 0.
Gx improves the characteristic of controlled object. GODMX and GODMN improve the phase characteristics
of controlled object. The greater both values are, the more advance value of phase it have. GCOEF is the
compensation parameter to improve the gain characteristics of controlled object. As the values are greater,
the value of gain gets greater. There is a predetermined parameter set fit to each properties of the motor such
as velocity gain and position gain. If there is not a parameter set you want to use, please consult to Kyushu
branch office, Servo Laboratory through the charged person of your nearest FANUC or GEFanuc office.
