p1806[0...n] Filter time constant Vdc correction / T_filt Vdc_corr
VECTOR Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
0.0 [ms]
Description: Sets the filter time constant of the DC link voltage used to calculate the modulation depth.
r1807 Actual DC-link voltage to calculate the modulation depth / VdcActValMod_depth
VECTOR Can be changed: -
Data type: Floating Point
P-Group: Displays, signals
Min
- [V]
Description: DC link voltage that is used to convert the setpoint voltage into an equivalent modulation depth.
Note: P1737 can be used for filtering.
r1808 DC link voltage actual value for V_max calculation / Vdc act val U_max
VECTOR Can be changed: -
Data type: Floating Point
P-Group: Displays, signals
Min
- [V]
Description: DC link voltage used to determine the maximum possible output voltage.
r1809 Modulator mode actual / Modulator mode act
VECTOR Can be changed: -
Data type: Integer16
P-Group: Modulation
Min
-
Description: Displays the effective modulator mode.
Values: 1:
2:
3:
4:

p1817 Minimum ratio, pulse frequency to the output frequency / Min f_puls / f_max
VECTOR Can be changed: C2
Data type: Floating Point
P-Group: Drive converter
Min
8.3
Description: Sets the minimum ratio between the pulse frequency and the output frequency.
Notice: If the ratio between the pulse frequency and the output frequency is reduced, then oscillations can occur in the out-
put current that can result in significant levels of current ripple with the appropriate negative effects.
