cos φ as per rating plate.
Feedback from the observer of the asynchronous machine. Affects the
accuracy of the speed approximation of the control mode 3:ASM - Sensorless
vector control. For values that are too large or too high, the stationary
difference between the reference and actual speed increases.
Proportional gain of speed approximation. Affects the dynamic properties of the
motor (especially the stability and overshoot behavior of the speed)
Notes on settings
The correct setting can be checked by means of the speed curve. If an encoder
is present during commissioning, E15 should be considered as the actual
speed, otherwise E91. B47 should not be less than 1% of B48. If values are too
small the drive may become instable and the resulting vibration will oscillate at
a mechanical frequency. By increasing B47, overshoots in the speed can be
dampened. Values that are too large lead to vibrations in the current and
speed.
Integral gain of speed approximation. Affects the dynamic properties of the
motor. The larger B48 is, the faster the motor model can follow the actual
speed.
Notes on settings
The correct setting can be checked by means of the speed curve. If an encoder
is present during commissioning, E15 n-motor encoder should be considered,
otherwise E91. If the motor can not follow the set speed ramp despite
sufficiently large torque limits, B48 must be increased. Values that are too large
lead to a fault 56:Overspeed
B19 cos(phi) version 0
B46 observer feedback version 0
Information
The amount of feedback is an option for reporting to the ASM
observer how exact the machine constants B54 leakage factor, B52
stator inductance and B53 stator winding resistance were
determined. The smaller the feedback selected, the more the ASM
observer depends on these constants.
