Figure 9-11 Example circuit for bypass with synchronizer without degree of overlapping
Activation
The bypass with synchronizer without degree of overlapping (p1260 = 2) function can only
be activated using a control signal. It cannot be activated using a speed threshold or a fault.
Parameterization
Once the bypass with synchronizer without degree of overlapping (p1260 = 2) function has
been activated, the following parameters must be set:
Table 9-7 Parameter settings for bypass function with synchronizer without degree of overlapping
Parameters Description
p1266 = Control signal setting when p1267.0 = 1
p1267.0 = 1
p1267.1 = 0
Bypass function is initiated by the control signal
p1269[0] = Signal source for contactor K1 feedback
p1269[1] = Signal source for contactor K2 feedback
p3800 = 1 The internal voltages are used for synchronization.
p3802 = r1261.2 Synchronizer activation is triggered by the bypass function.
p1200 = 1 The "flying restart" function is always active.
