Axis synchronisation via system bus (CAN)
The system bus (CAN) transmits the sync telegram and the process signals.
Application examples:
•
Selection of cyclic, synchronised position setpoint information for multi-axis positioning via the
system bus (CAN).

Fig. 7-221 Example for linking the FB SYNC1
Axis synchronisation via terminal control (X5/ E5)
The transmission paths for the sync signal and the process signals are separated.
•
The process signals are connected via a freely selectable input channel (e. g. AIF interface, DF
input).
•
The sync signal is injected via terminal X5/E5.
Application examples:
•
Selection of cyclic, synchronised position setpoint information for multi-axis positioning via
other bus systems (e. g. Interbus).
•
Synchronisation of the internal processing cycles of the FB to higher-level process controls.
