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.

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
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.
p1820[0...n] Reverse the output phase sequence / Outp_ph_seq rev
Access level: 2
Can be changed: C(2), T
Units group: -
Min
0
Description: Sets the phase sequence reversal for the motor without setpoint change.
If the motor does not rotate in the required direction, then the output phase sequence can be reversed using this
parameter. This means that the direction of the motor is reversed without the setpoint being changed.
