p1806[0...n] Filter time constant Vdc correction / T_filt Vdc_corr
Access level: 4
Can be changed: U, T
Units group: -
Min
0.0 [ms]
Description: Sets the filter time constant of the DC link voltage used to calculate the modulation depth.
r1808 DC link voltage actual value for U_max calculation / Vdc act val U_max
Access level: 4
Can be changed: -
Units group: 5_2
Min
- [V]
Description: DC link voltage used to determine the maximum possible output voltage.
r1809 CO: Modulator mode actual / Modulator mode act
Access level: 4
Can be changed: -
Units group: -
Min
1
Description: Displays the effective modulator mode.
Value: 1:

p1810 Modulator configuration / Modulator config
Access level: 3
Can be changed: U, T
Units group: -
Min
-
Description: Sets the configuration for the modulator.
Bit field: Bit Signal name
00 Avg value filter for U_lim (only for
Vdc_comp. in modulator)
01 DC link voltage compensation in the current
control
14 Deactivate maximum angular difference
adaptation
Notice: Bit 1 = 1 can only be set under a pulse inhibit and for r0192.14 = 1.
Note: Re bit 00 = 0:
Voltage limitation from the minimum of the DC link voltage (lower ripple in the output current, reduced output volt-
age).
Re bit 00 = 1:
Voltage limitation from averaged DC link voltage (higher output voltage with increased ripple in the output current).
The selection is only valid if the DC link compensation is not performed in the Control Unit (bit 1 = 0).
Re bit 01 = 0:
DC link voltage compensation in the modulator.
Re bit 01 = 1:
DC link voltage compensation in the current control.
