Parameterization
Once the bypass with synchronizer with degree of overlapping (p1260 = 1) function has
been activated, the following parameters must be set:

Transfer process
Figure 9-16 Signal diagram, bypass with synchronization with overlap
Transfer of motor to the line supply
( contactors K1 and K2 are activated by the converter):
● The initial state is as follows: Contactor K1 is closed, contactor K2 is open and the motor
is fed from the converter.
● The control bit "bypass command" (p1266) is set (e.g. by the higher-level automation).
● The bypass function sets the control word bit "synchronizing" (r1261.2).
