- Page 9 M‑5625 Digital Synchronizing System Minimum Frequency Difference The guaranteed minimum frequency difference for Auto-Sync operation is 0.0005 Hz. However, typical units consistently operate with frequency difference of 0.0001 Hz. Zero Phase Prediction Figure 4 illustrates the average closing phase error as a function of frequency difference for 80 ms, 100 ms, 200 ms, 400 ms and 800 ms breaker closing times.
