4.9.2 Process SYNC telegram

If synchronous PDO’s have been created in an frequency inverter, their processin

synchronized with the SYNC tele

ram. The SYNC tele

ram is

enerated by the system

bus master and is a telegram without data.

The identifier is 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 nodes on the system bus.

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

grams can be found there.

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

The data of the Rx-PDO’s are forwarded to the application after the arrival of the SYNC

telegram. At the same time, the transmission of the Tx-PDO’s with the currently avail-

able data from the application is triggered.
