System bus (CAN) for Lenze PLC devices

Axis synchronisation via terminal
The transmission paths for the sync signal and the process signals are separated.
· The process signals are applied via a freely selectable input channel (e. g. AIF interface, DF
input).
· The sync signal is injected via terminal:
PLC Terminal for sync signal
9300 Servo PLC X5/E5
Drive PLC X3/I1
ECSxA X6/DI1
Note!
For the synchronisation via terminal, in addition to the SB CAN_Synchronization the SB
DIGITAL_IO has to be included in the control configuration of the Drive PLC Developer Studio.
Examples for applications:
· Specification of cyclic, synchronised position setpoint information for multi−axis applications
via other bus systems (e. g. INTERBUS).
· Synchronisation of the internal process cycles to higher−level process controls.
Synchronisation time
After mains power−up and the initialisation time of the PLC, an additional period is required for
synchronisation.
The synchronisation time depends on
· the baud rate of the system bus
· the starting time (arrival of the first sync telegram/signal)
· the interval of the sync telegrams/signals
· the sync correction factor (C0363)
· the operating mode (C1120)
