Gains/Limits
Gains are used to adjust both the velocity and position loop performance. The velocity loop gains
should be set up first, and then the position loop gains can be set. Change gains with care as excessive
settings on any gain can result in motor instability.
After changing any Gain values, choose OK to store the new values and close the dialog box, choose
Update to store the new values, but still leave the Gains/Limits dialog box displayed or choose Cancel
to leave the dialog box without saving changes. The new values are not active until OK or Update is
selected.
