Asynchronous

The motor drive currently supports only Free Run mode (Asynchronous)
Free Run Mode (Asynchronous)
The master and slave stations run asynchronously. Each station has an individual clock that
calculates the time. In other words, the clocks of the master and slave are not synchronized.
The command and feedback transmissions between the master and slave are based on a
sequential order instead of a precise time synchronization. For example, the master sends a
PDO at time T1, and the slave receives the PDO at T2 after the SM2 event.
