Sync signal:
• 9300 Ser vo PL C: X5/E5
• Drive PLC: X3/I1
Synchronisation time
After power-on and the initialisation time of the PLC, additional time is needed for synchronisation.
The synchronisation time depends on
• the baud rate of the system bus
• the starting time (input of the first Sync telegram/signal)
• the time between the Sync telegrams/signals
• the Sync correction factor (C0363)
• the control mode (C1120)
Axis synchronisation via system bus (CAN)
The system bus transmits both the Sync telegram and the process signals.
Application examples:
• Input of cyclic, synchronised position setpoint information for multi-axis applications via the
system bus.
Axis synchronisation via terminal
The Sync signal and the process signals have different transmission paths.
• The process signals are connected via a selectable input channel (e.g. AIF interface, DF
input).
• The Sync signal is launched via the terminal:
PLC Terminal for Sync sig nal
9300 Servo PLC X5/E5
Drive PLC X3/I1
Application examples:
• Input of cyclic, synchronised position setpoint information for multi-axis applications via other
bus systems (e.g. INTERBUS).
• Synchronisation of internal processing cycles on higher-level process controls.
