Voltage Difference
The parameters 6150 dV SYNCHK V2>V1 and 6151 dV SYNCHK V2<V1 can be set to adjust the permissible
voltage differences asymmetrically. The availability of two parameters enables an asymmetrical release to be
set.
Frequency Difference
The parameters 6152 df SYNCHK f2>f1 and 6153 df SYNCHK f2<f1 determine the permissible
frequency differences. The availability of two parameters enables an asymmetrical release to be set.
Operating Range
The parameters 6154 dα SYNCHK α2>α1 and 6155 dα SYNCHK α2<α1 delimit the operating range for
switching under synchronous system conditions. The availability of two parameters enables an asymmetrical
release range to be set.
