EtherCAT SM-Watchdog:
This PDO monitoring function (PDO = Process Data Object) should be activated so that the inverter
does not continue with the last received reference values after a failure of the EtherCAT network or
the master.
If the value 65534 was set in another parameter A258 EtherCAT PDO-Timeout, the timeout can be
set in the EtherCAT master (TwinCAT software). The result is then indicated in this parameter:
Element 0 contains the resulting watchdog time in 1 milliseconds.

EtherCAT SM-Watchdog:
This PDO monitoring function (PDO = Process Data Object) should be activated so that the inverter
does not continue with the last received reference values after a failure of the EtherCAT network or
the master.
If the value 65534 was set in another parameter A258 EtherCAT PDO-Timeout, the timeout can be
set in the EtherCAT master (TwinCAT software). The result is then indicated in this parameter:
Element 1 contains whether the watchdog was just triggered (1) or not (0).
When the watchdog is triggered and the function is activated (see value 65534 in parameter A258),
the fault 52:communication is triggered on the inverter with cause of fault 6:EtherCAT PDO.

EtherCAT synchronization mode: Activation of EtherCAT synchronization mode on the
inverter. The inverter offers the option of monitoring the synchronization between master and
inverter via Distributed Clock. A check is made to determine whether the time difference between
the arrival of the EtherCAT Frame at the inverter and the point in time of the SYNC0 signal on the
inverter is within a tolerable time range.
When monitoring is activated, Sync errors are counted with an error counter and indicated in
parameter A261.2.
Synchronization mode is deactivated and activated by entering the following values:
0: Synchronization deactivated
1: Synchronization active
Other values are not defined and are therefore not permitted.
CAUTION
When the PLC cycle time is not the SYNC0 cycle time, all synchronization errors can no longer be
detected.
CAUTION
Activation of synchronization mode requires different amounts of run time depending on the cycle
time of the PLC and the inverter. With high-performance applications are being run on the inverter,
activation of synchronization mode may cause the error "runtime load."
