Exemplary presentation of the parameterizable friction torque-compensation characteristic
3.7.1.5.2
Reduction of the friction torque at 0 speed
If 0 speed is approached at motors with a high friction torque then in a lot of cases the
current is not reduced and remains at the torque current, which is required to overcome
the sliding friction. The friction torque reduction is switched on at speed 0 by bit 11 of
. The friction torque is reduced till such time as the current reaches 0. By the
waiting time
can be set how long is waited after recognizing speed 0, until the
friction torque reduction is initiated.
