4.8.2 SYNC telegram, generation

If synchronous PDO’s have been created on the system bus, the master must send the

SYNC telegram cyclically. If an frequency inverter has been defined as a system bus

master, the latter must generate the SYNC telegram. The interval for the SYNC tele-

ram of an frequency inverter defined as the system bus master is ad

ustable. 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 tele

rams can be

adapted by parameterization on the frequency inverter.

The identifier of the SYNC tele

ram must be set identically in all subscribers on the

system bus.

The setting of the identifier of the SYNC telegram is done via the parameter

SYNC-

Identifier

918.

to the Predefined Connection

Set.

Attention! The identifier range 129...191 may not be used as the emergency tele-

grams can be found there.

The temporal cycle for the SYNC is set on an frequency inverter defined as a system

bus master via the parameter

SYNC-Time 919.

Note:

A setting of 0 ms for the parameter

SYNC-Time 919 means "no SYNC

telegram”.
