Figure 9-15 Typical circuit diagram for bypass with synchronizer with degree of overlapping
The synchronized bypass with overlap (p1260 = 1) function can only be activated using a
control signal. It cannot be activated using a speed threshold.
Once the bypass with synchronizer with degree of overlapping (p1260 = 1) function has
been activated, the following parameters must be set:
Table 9- 7 Parameter settings for bypass function with synchronizer with degree of overlapping
Signal "Command switch motor - power unit"
Signal "Command switch motor - line supply"
p1266 = Control signal setting
Signal source for contactor K1 feedback
Signal source for contactor K2 feedback
Synchronization is activated
Synchronizer activation is triggered by the bypass function.
