Friction Compensation Selection
Use the following user constant to enable or disable friction compensation to determine whether
or not the friction of the servo system is to be taken into consideration for the calculation of load
inertia.
If this compensation function is enabled, select small or large friction compensation according
to the extent of friction in order to ensure highly precise load inertia calculation.
