Synchronisation of PDOs via sync telegram
8.4.1 Parameter setting
Short overview: Parameters for synchronisation via sync telegram
Sync source
C01120
is used to select the source of the synchronisation signals. Basically, only one
source can synchronise the node.
Sync cycle time
Time with which the internal phase-locking loop (PLL) expects the synchronisation signals.
The time must be set in C01121
in accordance with the cycle of the synchronisation source
selected in C01120
.
Example: For the system bus (CANopen), the interval between two synchronisation signals
has been set to 2 ms. If the system bus (CANopen) is to be used as synchronisation source,
a sync cycle time of 2000 μs must be set in C01121
.
