10 Restarting the EtherCAT fieldbus

During operation it may be required to restart the EtherCAT fieldbus. This can for instance be

necessary after fatal faults like a cable break.

 How to restart the EtherCAT fieldbus:

1. Activate the controller inhibit for the inverters.

2. Request restart of the EtherCAT master.

In the function block L_IODrvEtherCAT (FB)

( 140) from the Function library

L_IODrvEtherCAT.lib ( 110), set the input xRestart = TRUE:

Ethercat_Master.xRestart := TRUE;

The following steps are only required for Motion devices:

3. Execute the SMC3_ReInitDrive function block from the SM3_Basic.lib function library:

bExecute input:= TRUE;

4. Execute the MC_Reset function block from the SM3_Basic.lib function library:

bExecute input:= TRUE;

 Note!

When the EtherCAT bus is restarted, the control mode of the Motion drives is set to the

"CyclicSyncPosition" mode. If a different control mode was active before the restart,

change the control mode by means of the SMC_SetControllerMode function block.
