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:
