The screen view can only be used to configure P386[0] - CON_SCON_TFric. In
order to access all the friction torque compensation parameters, please switch to the
list view by using the “CTRL + L” key combination.
Fig. 7.31: Friction torque compensation for position control
The friction torque compensation is derived from the forward-fed speed nref_FF. It
has five basic functions, each having the Torque and Speed parameters. The basic
function runs proportionally up to the point (Speed, Torque), the function value
remains constant at higher speeds.
