Synchronisation of the internal time base of the controller
4.4 Synchronisation of the internal time base of the controller
In a drive system, synchronising the internal time bases of all controllers involved makes
sense because cyclic process data should be processed synchronously in all drives.
 One of the following signal sources can be used for automatic synchronisation of the
internal time base of the controller:
– CAN on board (sync telegram)
– Digital input
– Sync signal of a plugged-in communication module
(EtherCAT, PROFINET, or Powerlink)
Short overview of the parameters for the synchronisation of the internal time base:
Sync signal source
The synchronisation signal source can be selected in C01120
. As a general rule, only one
source can be used to synchronise the internal time base.
Sync cycle time setpoint
Time after which the internal phase-locking loop (PLL) anticipates the synchronisation
signals. The time must be set in C01121
according to the cycle of the synchronisation
source selected in C01120
.
Example: For the system bus, 2 ms has been selected as interval between two
synchronisation signals. If the system bus is to be used as synchronisation source, a sync
cycle time setpoint of 2000 μs must be selected in C01121
.
Sync phase position
The phase position determines the zero time of the application referred to the
synchronisation signal (bus cycle). Since PDO processing is an integral part of the system
part of the application, a change of the phase position also changes the acceptance time of
the PDO.
 If "0" is set, the application will start at the same time as the synchronisation signal.
