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.
