[3080.6]
A speed setpoint (e.g. r0060) is recommended as input variable of the friction characteristic if the speed actual
value can always track the speed setpoint.
When starting/reversing, in the range around standstill, the friction torque establishes itself as a function of the
speed. The rate at which the friction torque establishes itself can be scaled using p3849.
