Figure 2-109 Operating range under synchronous and asynchronous conditions for voltage
(V) and frequency (f)
Address 6x50dV SYNCHK V2>V1 and 6x51dV SYNCHK V2<V1 can be used to con-
figure the permitted voltage difference also asymmetrically. The availability of two pa-
rameters enables an asymmetrical release range to be set.
Address 6x52df SYNCHK f2>f1 and 6x53df SYNCHK f2<f1 determine the per-
missible frequency differences. The availability of two parameters enables an asym-
metrical release range to be set.
Addresses 6x54dα SYNCHK α2>α1 and 6x55dα SYNCHK α2<α1 confine the oper-
ating range for synchronous switching. The availability of two parameters enables an
asymmetrical release range to be set.
The following tables only list settings and messages for function group 1. The settings
and messages of function groups 2 to 4 are the same type.
