Cause

The cause varies according to the value of <code>:

•the drive is in "operation enabled" and the sync message (SM mode or DC mode) does not arrive after 1.3 periods of the "communication cycle period," and is therefore considered as "missing Sync message"

•no data is received from the CU, or the CU does not read the data correctly

•no data exchange with Sinamics. Possible causes:

othe EtherCAT watchdog has expired while the ESM is in Op mode

othe maximum variation of the Sync PLL is more than 10% of the Sync base time

othe error of the Sync PLL is beyond an acceptable value

oCurrent Sync mode is in FreeFun
