Parameters
11.2 Parameter list
Parameter Specifications
Description: Sets the filter type for VIBSUP. Depending on the selected filter type, the VIBSUP filter
results in motion sequences that take somewhat longer.
0: The rugged VIBSUP filter has a lower sensitivity to frequency offsets compared with the sensitive
•
filter type, but results in a higher delay of the motion sequence. The total motion sequence is ex-
tended by the time period T
1: The sensitive VIBSUP filter has a higher sensitivity to frequency offsets compared with the rug-
•
ged filter type, but results in a lower delay of the motion sequence. The total motion sequence is ex-
tended by half the time period T
p31585 VIBSUP filter frequency f
Min: 0.5
Data type: Float
Description: Sets the frequency of the damped natural vibration of the mechanical system. This fre-
quency can be determined by making the appropriate measurements.
Note: The maximum frequency that can be set depends on the filter sampling time.
p31586 VIBSUP filter damping
Min: 0
Data type: Float
Description: Sets the value for the damping of the natural mechanical vibration to be filtered. Typically,
the damping value is about 0.03, and can be optimized by performing the appropriate positioning tests.
Read-only parameters
Parameter Name
r0020 Speed setpoint smoothed
Description: Displays the currently smoothed speed setpoint at the input of the speed controller or U/f
characteristic (after the interpolator).
Note: Smoothing time constant = 100 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
The speed setpoint is available smoothed (r0020) and unsmoothed.
r0021 Actual speed smoothed
Description: Displays the smoothed actual value of the motor speed.
Note: Smoothing time constant = 100 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
The speed actual value is available smoothed (r0021) and unsmoothed.
r0026 DC link voltage smoothed
Description: Displays the smoothed actual value of the DC link voltage.
Note: Smoothing time constant = 100 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
The DC link voltage is available smoothed.
r0027 Absolute actual current smoothed
Description: Displays the smoothed absolute actual current value.
Notice: This smoothed signal is not suitable for diagnostics or evaluation of dynamic operations. In this
case, the unsmoothed value should be used.
