Activation
The synchronized bypass with overlap (p1260 = 1) function can only be activated using a
control signal. It cannot be activated using a speed threshold.
Parameterization
Once the bypass with synchronizer with degree of overlapping (p1260 = 1) function has
been activated, the following parameters must be set:
Table 9- 10 Parameter settings for bypass function with synchronizer with degree of overlapping
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 Synchronizer activation is triggered by the bypass function.
