Operating mode
Code Value Function
C1120
0 FB without function.
Switches the data at the inputs directly to the outputs.
1 CAN Sync active
Synchronizes the controllers to the sync telegram of the system bus.
2 Terminal Sync active
Synchronizes the controllers to the sync signal of terminal X5/E5.
Synchronization time
After the mains connection and the initialization time of the controller, the FB SYNC1 also requires
a synchronization time.
The synchronization time depends on
l
the baud rate of the system bus (CAN-SYNC),
l
the start time (input of the first SYNC telegram/signal),
l
the time between the SYNC telegrams,
l
the SYNC correction factor (C0363),
l
the operating mode of the FB SYNC1
Axis synchronization via system bus (CAN)
The system bus (CAN)transmits the sync telegram as well as the process signals.
Application examples:
l
Input of cyclic, synchronized position setpoint information, e.g. multi-axis control via the
system bus (CAN).
