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.
Settings
Addresses which have an appended “A” can only be changed with DIGSI, under “Additional Settings”.
