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)
