Frequency sync gain determines how fast the synchronizer re-
sponds to an error in speed or phase. Adjust gain to provide sta-
ble control during synchronizing. Lower value to slow response.
Frequency sync integral gain compensates for delay in the syn-
chronizer control loop. Prevents low frequency hunting and damp-
ing (overshoot or undershoot). Lower value to slow response.
The Phase matching gain increases or decreases the influence of
the phase angle deviation to the frequency control. Prevents fre-
quency hunting and damping (overshoot or undershoot) when the
synchronizer is enabled with phase matching function.
Phase matching is started if the frequency difference between the
systems to be synchronized is below the configured value.

2 0 to 60.0 s 0.5 s Dwell Time: This is the minimum time that the generator voltage,
frequency and phase angle must be within the configured limits
before the breaker will be closed. Set to lower time for quicker
breaker closure commands.
