Activation
The bypass function with synchronization with overlap (p1260 = 1) can only be
activated using a control signal (p1267.0 = 1, p1267.1 = 0, p1267.2 = 0); it is not
possible to activate this function using a speed threshold or a fault.
Example
The following parameters must be set after the bypass function with synchroniza-
tion with overlap (p1260 = 1) has been activated.
