Clock frequency of the drive controller power board.
Increasing the clock frequency improves the control dynamics and reduces the
amount of noise produced, but also leads to increased losses (derating of the
power stage R04, R26).
In some operating states the clock frequency is changed by the drive controller
itself. The currently active clock frequency is displayed in E151.
Large motors may be subject to resonant vibrations at idle. Increasing
parameter B31 has the effect of dampening these vibrations if B20 = 1:ASM -
V/f-slip compensated. Values in the range of 60 ... 100 % are suitable for
problematic drives.
The reaction rate of the control mode 1:ASM - V/f slip compensated to changes
in load can be adjusted with B32. The smaller B32 is, the greater the dynamics
of the drive.
Stator resistance R
U-V
of the motor winding in ohms. Processing with this
parameter is only possible for third-party motors. The value can be autotuned
with action B41 autotuning.
Ratio of the tilting moment of the motor to the nominal torque.
Frequency of the voltage applied to the motor.
Display of the current speed reference value (RV) in user units based on the
profile generator and the v-RV low pass. The total of the position controller
output and speedFeedFwd (=speed controller reference value) is displayed in
Position operating mode. E06 shows the same value in reference to the motor
shaft.
B24 switching frequency version 2
Information
The factory setting of this parameter depends on B20. If a
synchronous servo motor or synchronous linear motor is used, the
value 8:8kHz is entered in B24. If an asynchronous machine is
used, B24 has a value of 4:4kHz.
