Ratio of the tilting moment of the motor to the nominal torque.
Control modes B20 = 2:ASM - vector control and 3:ASM - sensorless vector
control have an efficiency controller. It attempts to operate the motor at its
energetically optimal point. The output variable of this controller is the
reference flux, which is controlled by the current in direction d (E92: Id). The
parameter B69 Minimum magnetization part load is the lower limit for the
nominal magnetization in the part-load range. In the field-weakening range,
smaller fluxes can also occur than those set in B69.
Information
The larger B69 is set, the larger is the possible dynamics. 100% means
maximum dynamics and minimum efficiency.
With small values for B69 it may be necessary to adjust C31 proportional gain
n-control as the motor otherwise tends to vibrate.
Entry point into field weakening.
The set value affects the dynamic properties of the drive.
Setting instructions:
• The smaller the value the better the dynamic properties.
• The larger the value the lower the power consumption at a given working
point.
You can use this parameter to adjust the derating of the speed controller field
weakening range.
DC link connection (peak value).
Motor voltage (chained RMS value).
Frequency of the voltage applied to the motor.
Current motor encoder speed.
The speed determined from the motor encoder specified in B26 and filtered
with the motor encoder speed low pass C34.
Information
The default value is adequate for most motors and applications.
Adjustments are only necessary in some circumstances when
connecting a third-party motor. In these cases the value can be
autotuned with action B41 autotuning. However, this adjustment
should not be performed until you have consulted with STOBER.
