Description: Displays the smoothed actual value of the input voltage.
Index: [0] = Voltage at the input terminals of the power unit
[1] = Voltage at the VSM and at the input terminals of the line filter
[2] = Voltage of the voltage source from the line supply model
[3] = Smoothed voltage of the voltage source from line supply model
Dependency: Refer to: r0072
Note: Smoothing time constant = 300 ms
The signals are not suitable as process quantity and may only be used as display quantities.
The input voltages are available smoothed (r0025) and unsmoothed (r0072).
r0025[0]: Pulsed voltage at the line supply input terminals of the power unit. The value is calculated from the modu-
lation depth r0074 and is therefore only correct in the closed-loop controlled mode and when the pulses are
enabled.
r0025[1]: Absolute voltage at the input terminals of the line filter or the connection point of a VSM. The value is cal-
culated from the VSM measured values r3661 and r3662 and is therefore equal to 0 if a VSM is not connected.
r0025[2]: Estimated value for the voltage of the voltage source that is calculated in the voltage model of the line
supply PLL.
r0025[3]: Smoothed display value of the filtered source voltage from r0072[3].
Description: Displays the smoothed output voltage of the power unit.
Dependency: Refer to: r0072
Note: Smoothing time constant = 100 ms
The signal is not suitable as process quantity and may only be used as display quantity.
The output voltage is available smoothed (r0025) and unsmoothed (r0072).
Description: Displays the smoothed actual value of the DC link voltage.
Dependency: Refer to: r0070
Notice: This smoothed signal is not suitable for diagnostics or evaluation of dynamic operations. In this case, the
unsmoothed value should be used.
Note: A_INF, B_INF, S_INF: smoothing time constant = 300 ms
