2.8. Example of SCAN time
Below table is the recommended scan time depend on the number of the drive and the baud rate.
1 unit : Tx 8byte(4word) / Rx 8byte(4word) ･･･ total 129bit (include stub 5 bits)
Delay : 3.5ms

Ex. 1Mbps, 1TPDO, 1RPDO, 80%, 3.5ms delay
Time = 129bit x 64unit x 2PDO / (1e6) / (80%/100) +3.5ms+@
= 25ms
