I think that it would be preferable to stop the drive without 
breaking/modifying the EtherCAT communication, so that you can continue 
to monitor the drive when it is stopping.

Which servo drive do you have ?

If you have a Kollmorgen AKD,

- You can configure DRV.DISMODE to trigger a controlled stop when the 
drive is disabled. In this case you can stop the motion by disabling the 
drive with the ControlWorld Object (0x6040:0x0),

- You can also trigger a MACRO with a digital input. In this case it 
opens many other possibilities.
