This gives a pretty good explanation of its use. Thespeed loop proprotional gain (k_P) will transition fromone low speed settingto another high speed setting. Similar effects can be had with the integral gain,T_N. The transition is more-or-less linear across the transition range. Once set there is no need to makeadjustments via Profibus DP. It is automatically taken care of for you. When using a 1PH7 motor with S120 drives, the speed controller adaption is automatically set for you. You may find that the gain settings (i.e., p1460 and p1461) may need to be adjusted slightly in some applications. Typically the speed loop gain settings for 1PH7 applications are not that critical unless you're trying to use the motor in a positioning application. Hope this helps...
