9.3.8 Friction characteristic curve
Description
The friction characteristic is used to compensate for the frictional torque of the motor and
driven load. A friction characteristic allows the speed controller to be pre-controlled and
improves the control response..
10 points along the characteristic are used for the friction characteristic. The coordinates of
every point along the characteristic are defined by a speed parameter (p382x) and a torque
parameter (p383x) (point 1 = p3820 and p3830).
Features
● There are 10 points along the characteristic to represent the friction characteristic.
● An automatic function supports the friction characteristic plot.
● A connector output (r3841) can be interconnected as friction torque (p1569).
● The friction characteristic can be activated and de-activated (p3842).
