Parameters
10.2 Parameter list
Par. No. Name
p31585 VIBSUP: Filter frequency
f
d
Description: Sets the frequency of the damped natural vibration of the mechanical system. This frequency 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
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
Par. No. Name
r0020 Speed setpoint smoothed
Description: Displays the currently smoothed speed setpoint at the input of the speed controller or U/f charac-
teristic (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.
Notice: When measuring a DC link voltage < 200 V, for the Power Module (e.g. PM340) a valid measured
value is not supplied. In this case, when an external 24 V power supply is connected, a value of approx. 24 V
is displayed in the display parameter.
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 (r0026) and unsmoothed.
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.
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 absolute current actual value is available smoothed (r0027) and unsmoothed.
r0029 Current actual value field-generating smoothed
Description: Displays the smoothed field-generating actual current.
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 field-generating current actual value is available smoothed (r0029) and unsmoothed.
