Description:
Display and connector output for the torque of the friction characteristic dependent on the speed.
Dependency:
Refer to: p1569, p3842
Description:
Setting to activate and deactivate the friction characteristic.
Value:
0:
Friction characteristic deactivated
1:
Friction characteristic activated
Dependency:
Refer to: p1569, r3841, p3845
Description:
Sets the smoothing time constant (PT1) for the friction torque difference.
Smoothing is activated when switching over from status bit r3840.9.
Dependency:
Refer to: p3844
Description:
Selects the upper changeover point of the friction characteristic for the frictional torque input controlled by the motor
model of the induction motor.
The speed of this changeover point is pre-assigned when automatically calculating with the changeover speed
p1752. The changeover point located below is pre-assigned with the changeover speed p1752 * (1 - p1753).
Example:
p3844 = 3 means that the speed value for the change to the monitor model (p3823 = p1752) is entered into p3823
(friction characteristic value n3).
Depending on the display of r3840.9, the frictional torque is calculated from the friction characteristic values, which
are associated with these changeover points. For the changeover of the motor model, with hysteresis, the frictional
torque smoothed with p3843 changes between these two states.
Dependency:
As part of the automatic calculation (p0340), p3844 is only activated for closed loop control (p1300 = 21, 23) of
induction motors with encoder.
