Parameter setting
Short overview: Parameters for synchronisation via sync telegram
Sync source
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
in accordance with the cycle of the synchronisation source
selected in
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
μ
