10.2 Sync frame failure detection

During the Synchronisation with "Distributed Clocks" (DC) ( 37), this monitoring checks whether an

EtherCAT PDO telegram (Sync Manager 2 Event) has arrived between two signals.

For this purpose, the communication module comes with an internal EtherCAT telegram failure

error counter. The telegram failure error counter is incremented by the value '3' in case of a telegram

failure. For each PDO received correctly, the counter is decremented by ’1’. If the internal telegram

failure error counter reaches a threshold adjustable in CoE object 0x10F1.2, a change to "Safe-

Operational" takes place and the "Sync telegram failure [0x01bc8700]

" error message is output.

In the standard setting, monitoring is deactivated (0x10F1.2 = 0). A sensible setting is a value > ’5’

in order that an error will only be triggered in the inverter when a second telegram fails.

An error response can be set via code C13880/2

("0: No response" is preset here).

10.3 Interruption of internal communication

The response to a communication error between the communication module and the standard

device can be set in the standard device code C01501

(module in the MCI slot).

An externally supplied communication module reports a connection abort to the standard device

via an emergency telegram to the master and changes to the "Safe-operational" state.

The error message "Lost connection to 8400 [0x01bc3100]

" ( 93) is output.
