[Etherlab-users] dynamic PDO unmapping

[BUSSIERES Vincent]

Dear All,

Thanks a lot for your help. I placed servo drive slave into its own domain. Obviously I needed to desactivate heartbeat.
It may not be the best solution but it works....

Hi,

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.
