4.4.2.3.1 Synchronization CBA
ID Parameter CL Setting range
[Default]
Description
5730 Synchronization CBA 2 [Slip frequency] The LS-5 instructs the frequency
controller (e.g. easYgen) to adjust the
frequency in a way, that the
frequency of the variable system is
marginally greater than the target.
When the synchronizing conditions are
reached, a close command will be
issued. The slipping frequency is
positive to avoid reverse power.
Phase matching The LS-5 instructs the frequency
controller (e.g. easYgen) to adjust the
phase angle of the variable system to
that of the target, in view of turning
the phase di󰈠erence to zero.

frequency separate o󰈠set
(easYgen-3400XT/3500XT version
1.13 and higher, parameter 6676).
[O󰆞 ] The easYgen(s) take the slip
frequency o󰈠set (easYgen parameter
5502) of the GCBs.
Notes
This parameter is only visible if the
LS-5 'Synchronization CBA' (parameter
5730) is set to 'Slip frequency'.
This parameter is only valid if the
easYgen is in application mode
GCB/LS5
A02
and if the LS-5
'Synchronization CBA' (parameter
5730) is set to 'Slip frequency'.
The parameter 6676 is only
implemented in easYgen-3400XT/
3500XT version 1.13 and higher. In
combination with other devices the
parameter described here
5709 has
no impact.

The prerequisite for a connect
command being issued for the CBA is
that the di󰈠erential frequency is below
the con󰈡gured di󰈠erential frequency.

system (i.e. generator), this
