Address 6x50dV SYNCHK V2>V1 and 6x51dV 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 6x53df SYNCHK f2<f1 determine the permissible frequency dif-
ferences. The availability of two parameters enables an asymmetrical release to be set.
Parameters 6x54 dα SYNCHK α2>α1 and 6x55 dα SYNCHK α2<α1 confine the operating range for synchro-
nous switching. The availability of two parameters enables an asymmetrical release to be set.
Settings and Information
The following tables only list the settings and messages for function group 1. The settings and messages of
function groups 2 to 4 are the same type.
