Note
For bit 00 = 1:
The parameter for activation/duration has been set (p3380 > 0) - however, forming has still not been started (p0840 =
0 signal).
For bit 01 = 1:
The parameter for activation/duration has been set (p3380 > 0) - however, forming has still not been started (p0840 =
0/1 signal).
This status is displayed through alarm A07391.
The procedure can be interrupted via binector input p0840, p0844, p0848 (r3382.1 = 0) - and reactivated again using
p0840.
For bit 03 = 1:
Forming was not able to be successfully performed within the set duration.
This status is displayed using fault F07390.

DC quantity controller configuration / Rect_ctrl config
Access level: 3
Can be changed: T, U
Unit group: -
Min:
-
Description:
Sets the configuration for the DC quantity controller in the overmodulation range.
There is no DC quantity control for power units that can also be connected through 1 phase to the line supply (r0204.15
= 1).
Bit field:
Bit

Dependency:
The modulator mode p1802 must enable operation in the overmodulation range. In addition, the overmodulation limit
p1803 must be greater than 103 %.
Set the modulator mode p1802 = 10, if the DC quantity control is deactivated and overmodulation is to be prevented.
