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.

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
.
