If synchronous PDO's have been created on the system bus, the master must send the
SYNC telegram cyclically. If a frequency inverter has been defined as a system bus
master, the latter must generate the SYNC telegram. The interval for the SYNC tele-
gram of a frequency inverter defined as the system bus master is adjustable. The
SYNC telegram is a telegram without data.
The default identifier = 128 according to the Predefined Connection Set.
If a PC or PLC is used as a master, the identifier of the SYNC telegrams can be
adapted by parameterization on the frequency inverter.
The identifier of the SYNC telegram must be set identically in all nodes on the system
bus.
The setting of the identifier of the SYNC telegram is done via the parameter
