Parameters 6x44 dα SYNC α2> α1 and 6x45 dα SYNC α2< α1 confine the operating range for synchro-
nous switching. These two parameters allow an asymmetrical switching range to be configured (see
Figure 2-132).
Moreover, the release time delay T SYNC-DELAY (address 6x46) can be set during which all synchronous
conditions must at least be fulfilled for the closing command to be generated after expiration of this time.

Address 6x50 dV SYNCHK V2>V1 and 6x50 dV SYNCHK V2>V1 can be used to configure the permitted
voltage difference also asymmetrically. The availability of two parameters enables an asymmetrical release
range to be set.
Parameters 6x52 df SYNCHK f2>f1 and 6x53 df SYNCHK f2<f1 determine the permissible frequency
differences. The availability of two parameters enables an asymmetrical release to be set.
