Figure 9-23 Example circuit for bypass with synchronizer without degree of overlapping
Activation
The synchronized bypass without overlap (p1260 = 2) function can only be activated using a
control signal. It cannot be activated using a speed threshold.
Parameterization
Once the synchronized bypass without overlap (p1260 = 2) function has been activated, the
following parameters must be set.

Parameter Description
r1261.0 Signal "Command switch motor - power unit" (contactor K1)
r1261.1 Signal "Command switch motor - line" (contactor K2)
p1266 = Control signal setting
p1269[0] = Signal source for contactor K1 feedback
p1269[1] = Signal source for contactor K2 feedback
p3800 = 1 Synchronization is activated
p3802 = r1261.2 Synchronization activation is triggered by the bypass function
p3809 =
Setting the phase setpoint for synchronizing the drive to the line supply
